Why Skype maybe right about killing its Extras developer program and being careful with APIs

So Skype kills its Extras developer program and everyone in VoIP and his dog is up in arms. I am not to happy either, but I think I understand the VoIP market leader: Skype has to be very careful because Skypeout is by far not the cheapest solution for internet phone calls. Competitors like Sipgate or Betamax always stress this point in their press releases. E. g. on August 5th, 2009, I got this email from the Betamax company Voipbuster:

As it is now becoming more and more clear that Skype’s services will not be available much longer because their software license will expire, it is now the time to switch to VoipBuster. [...] To make sure everyone can still use Voice Over IP at even cheaper rates than Skype, Voipbuster has lowered loads of destinations.

Sipgate basically said the same with its lates press release on August 19th, 2009. Everyone wants to eat from Skype's lunch.

If Skype allows developers to treat the call function as a service inside of other applications, it can only loose. When people can make their Skype calls on Facebook, Outlook, normal phones or wherever, they will use Skype only for inbound calls and for the free Skype to Skype calls. Outbound calls to phone networks (PSTN) will be channeled over Skype competitors who offer cheaper prices for their SIP services.

With some VoIP tinkering, I have already achieved most of this: I receive Skype calls on my normal phone, which is connected to a small PBX device (Fritz!Box), outbound calls to the PSTN go over cheaper competitors. So Skype never gets money from me. The only thing that is still missing are Skype to Skype calls from my Fritz!Box. They would be possible if Skype was more open, they way I already make and receive Gizmo5 calls on this box (which, BTW, doesn't earn money from me either).

If Skype allows that too - they will never see me again, although I would be a daily freerider on their network. I would not pay for Skypeout (as I already don't do) and I wouldn't even open their software on my PC, which they could at least use as a screen for visual advertising.

I repeat my concerns: If Skype opens too much, they can become the dumbest pipe of all. Other companies and services would channel their calls for free over Skype's gratis P2P network. Gizmo5 already does it with their OpenSky service: It let's you "call Skype or receive Skype calls" on SIP devices (at least they say so). Gizmo5 thus piggybacks its service on Skype's network and charges its users $20 per year for OpenSky. Skype gets nothing, that's the disadvantage of not having an own phone network but APIs. Truphone, Nimbuzz and Fring offer similar Skype services for mobiles.

I guess the new Skype owners have already considered this.

Finally Fring reveals how it wants to make money

Many people were wondering during the last two years how the Israeli mobile VoIP company Fringland Ltd. wants to make any money. Their versatile software works on virtually every platform and supports more than 1.000 mobile handsets. I heard that 200.000 new users sign up every month to Fring, as well as 80 companies which want to become a SIP affiliate. More than 500 SIP companies are already using the Israeli software as an easy to deploy solution for mobile VoIP, by sending a preconfigured Fring to their users' handsets or telling their customers how to use it. Fring invested heavily in software development and has to channel the other 500 companies' traffic over its own servers. Every voice connection goes first from the cellphone to Fring's servers, no matter if it's on Skype, SIP or Google Talk. Fring could take its share from the other companies' earnings, but hey do it for free. Also there is no paid version of Fring. All these business ideas are still in the cloud.

So how does Fring want to make money?

The cell phone multi messenger, which also serves perfectly for nearly free VoIP calls over 3G, should soon be sponsored by advertising. At the OSiM World conference in Berlin I saw an unreleased software version with banner ads for McDonald's in Fring's chat window. In a former occassion I could already see advertising by Gillette. The Israeli company with $20 million in venture capital seems to finally care now for revenue streams. Although CEO Avi Shechter had told me in February in an interview at Barcelona's Mobile World Congress that the entire year of 2008 would be dedicated exclusively to software development and revenues would be irrelevant. "The McDonald's banner ads are just a demonstration", said Fring's cofounder Boaz Zilberman when we met in Berlin. So until now Fring makes no money from advertising but is proving the concept.

One problem is, says Boaz, that mobile advertising is not very common yet. The advertisers still don't understand it and therefore employ only small budgets. But these small budgets would be eaten up immediately on the millions of daily Fring messages. That's why the company is going for bigger clients and advertising networks like Doubleclick or others. Context sensitive advertising like at Google Mail is not on the agenda. "We would have to read every chat message", says Boaz. "But we don't want that because it would hurt our users' trust." The business model of another Israeli born company seems creepy: Pudding Media is even eavesdropping their users' conversations to deliver targeted advertising at the computer screen during the phone calls.

Fring is now developing from a sole software for messaging and VoIP to an universal contact solution, which even keeps track of your buddies' location by GPS. The latest version 3.36.6, which you can only download from Fring's developer website, has already joined the menus for messengers and social networks. The boundaries between these categories are every time more blurry, because for instance Facebook is also an instant messenger now. In future software versions, every person should appear only once in Fring's contact list. Until now some people appear twofold, threefold or even more times - because they are connected to Skype, MSN, ICQ or other services at the same time. One click at the buddy's icon will start a chat, no matter which messenger to other person is using, which can always be escalated into a Fring phone call via VoIP.

Why Truphone and Gizmo5 applaud that Nokia turns it's back on mobile VoIP

Om Malik has asked "Is Nokia Turning Its Back on MobileVoIP?", pinpointing to the fact that the new Nseries devices N78 and N96 lack an own SIP client, while Nokia before embraced mobile VoIP on it's Nseries and Eseries devices. Charlie Schick of Nokia Conversations says the report of the death of VoIP has been "grossly exaggerated" and people like Phoneboy, Gizmo5's Michael Robertson or the company Truphone are buying that argumentation, although it has its flaws. Truphone, Gizmo5 and Fring must have realized immediately that they are winning from Nokia's move. That's why they are holding back their horses.

Nokia says that it's no problem that they have removed the native SIP client from their latest handsets, since companies can develop their own VoIP software based on great APIs. But it's not as easy as Nokia is trying to say: There are hundreds or thousands of companies without an own software for mobile VoIP. They just rely on the SIP standard. In Germany it's GMX, 1&1, Sipgate and the several Betamax daughters. Together they have millions of customers, I am one of them. These people cannot use VoIP on the new Nokia phones. I have always ten or more VoIP providers installed on my Nokia E61i's SIP client. This way I can always use the cheapest route and leverage free on net calls.

It would be nasty if had to install ten or more pieces of software for that purpose. It's already annoying that Truphone requires a special software because they don't give me my SIP password. That's a perversion of the idea of standards. If I need a special software for every company's offer why is there a standard called SIP?

So as a VoIP tinkerer I have to stay with the older Nokia devices, or at most I can change to the E71. But Nokia's new Symbian release, S60 3.2, is no option for me - as long as it has no own SIP client. It's obvious why companies like Fring, Truphone, Gizmo5, Vyke and others are applauding the Nokia move. It ties their customer to them and makes it more difficult to use other companies' offers. With a native SIP client, which allows to be connected to several different SIP services at the same time, I can be promiscuous. Even the most disruptive mobile VoIP companies prefer to lock me in their walled garden, but I don't want that.

I still believe that pressure from mobile operators has caused this move of Nokia. HSDPA and HSUPA have brought great bandwith to the latest handsets, enough to use it for Voice over 3G. With the right voice codec you can talk about 15 minutes and use only 1 Megabyte of data. Filtering for VoIP packets slows down the mobile data networks and therefore it's not very common. If you combine that with the right VoIP provider, like Betamax, this means free mobile phone calls to more than 30 countries. Only data prices apply.

Call Skype contacts from a mobile phone's browser with Hipsip!

Hipsip is a nice and easy mobile VoIP service which let's you call Skype and SIP contacts from a normal cell phone without a Wifi or 3G data connection. In the last weeks I could try out the service as beta tester and now they open to everyone. Hipsip does basically the same like iSkoot or Mobivox, but is easier to handle. You don't have to install a software on the mobile phone or talk to a computer voice to establish the connection. The user just opens a mobile website where he sees his Skype contacts and calls them with a click on the name. The phone then starts a GSM call to the nearest Hipsip callthrough number where a server converts it into a Skype call. In my case it goes to a landline number in Hamburg, Germany.

Screenshot from the Hipsip mobile website.

One big difference is that Hipsip has no hosted bridge from the cell phone network to Skype. Your computer must always be switched on and you have to install a small software called Hipsip Bridge which has to be running together with Skype. Otherwise the mobile website on the phone says "Please connect your Hipsip Bridge to see your Skype contacts." That is a big disadvantage to the other mobile phone Skype services like iSkoot, Mobivox and Fring. But at least it's cheaper than ideas from SkyQube or VoSky. They not only require you to leave your computer running, but also to buy an extra hardware which hands your mobile phone calls over to Skype. Again, they also let you receive Skype calls on a cell phone.

Call your Skype contacts with one click on a hyperlink.

If the Hipsip Bridge doesn't run, you can still call every SIP address of choice or even email addresses, which will be explained later. I conducted a small email interview to the developer Christian Rees. He comes from Germany himself, where he long time ago used to write about Atari ST computers for the famous c't magazine. On the phone he had told me that they are already considering a hosted solution without Hipsip Bridge, but that's not so easy.


I see that you use HTML code like <a href="tel:+4940306988028">Call sip:johndoe@ipcall.com</a> on your mobile website. What does it do? A computer's browser doesn't know what to do with it, but a cell phone starts a call.

The answer is, that the so called telephone URL, tel:, is supported on converged devices (in the sense that they support circuit and packet data) like cell phones with a web browser. When a tel: URL link with a phone number is clicked in the browser, the phone starts dialing the number. It works on all phones that are less then 4 years old. It's customary for the phone to prompt the user with the number, as a safeguard. Our users can be assured that we are only returning our local callthrough numbers.

Who is the company behind the Hipsip offer, Sipcall.com?

Sipcall.com Inc., the parent of Hipsip, is a California corporation with offices in Menlo Park. The company was founded in 2004, is privately funded and in the process of raising more capital. We are less then 10 people with backgrounds from academia, VoIP and the mobile industry. We consider ourselves an international company, that happens to be located in Silicon Valley.

Our history goes back quite a bit, starting in 1999, with the idea that email addresses will eventually turn into phone numbers. We attempted to raise funding in 2000, targetting the mobile space already back then. However, it took until 2004 for the climate to be right to start again with new ideas. In early 2005 we began developing the Hipsip Bridge for Skype. Due to our funding situation back then, it has taken until now for the relase.

What are your further plans?

We are planning to make Hipsip more useful and convenient for our users. One priority is to improve the Skype experience. We have already put emphasis on providing ISDN like voice quality for Skype calls over SIP, since Skype is so exceptional in this respect and we don't want to loose too much of that. However, there are limitations to the current phone networks. We are not so hot on vaporware, so we'll announce new features when they are available. And we are very interested to hear from users what they need.

When will it be hosted, so that my computer doesn't need to stay switched on?

See above, but it is a high priority for us.

And what about new features?

One novel feature that we provide is EmailCall. With EmailCall, a user can turn their email address into their phone number, so to speak. This is how it works: if the user has verified his mobile number and email address and opts-in to EmailCall, he can now be called by his email address:

• by dialing the email address on any SIP phone registered on Hipsip, which will ring the users SIP devices (you could say we are sippyfying the email address).


• from any mobile phone by entering the URL: hipsip.com/john.doe@aol.com (as an example). When the URL is entered, the current mobile number of the owner of the email address will be returned. This is limited to other users of Hipsip, and is strictly an opt-in feature. The user can change his current number anytime, while the much easier to remember email address can be used to look it up in real time, and dial immediately.

The idea behind this is, that we will eventually see a convergence in the addressing space just as we are seeing it with networks becoming all IP, so that a single SIP/email/URI address will be sufficient for all the different modes of communications for which we have to remember identifiers today. This day is not here yet, but we believe that it will eventually happen. Today it is already possible to dial a URI on the Nokia N-Series and E-Series phones, which works very well over WLAN and 3G. Things will only improve when pure packet networks like Wimax and LTE come online.

My take: we have to wait and see how Hipsip develops. The market for such services is already crowded. But nobody has built yet the perfect bridge from Skype to SIP. Hipsip has potential if they get the service hosted, but then they would have to cover higher server costs. The EmailCall is funny but nothing new. Jangl already does it for nearly a year.

Native Skype for Symbian announced – not by Fring and not by Skype

One thing I heard in Barcelona was that the mobile network operator 3 is not so happy with the 3Skypephone. People are allegedly using it like crazy and 3 is required to install more and more servers from the US startup iSkoot which powers the service. As you remember the 3Skypephone doesn't do mobile VoiP but makes an GSM call from the phone to the 3-iSkoot server, which then cannels them over the fixed line internet to Skype. The data connection is only used to show the presence of the Skype buddies. These iSkoot servers must be quite expensive.

Skype on mobile phones is generally a problem, said Eric Lagier, Business Development Director for Mobile at Skype, last year. A native version exists only for Windows Mobile devices because only they have a strong enough CPU. Symbian users already gave up all hope for a native Skype on their handsets. For more than two years they are waiting for Skype to solve its battery drain and latency problems. Only a prototype was reported in February 2006. Symbian users still have to rely on 3rd party applications like Fring, iSkoot or Mobivox – most of them eat up phone minutes.

But now a real native Skype version for Symbian cell phones will come out, I have been told at the Mobile World Congress. Maybe next week already. It will enable to make Skype calls over 3G and Wifi. The most interesting fact is that this software will NOT be released by Skype and also not by the Israeli software maker Fring, which until now was the only option for a Skype data call. Stay tuned and remember that you read it here first! I am quite excited to see when this rumour will really come true. Unfortunately I cannot tell the name of the company to not ruin their surprise.

Great contacts and exclusive information from the Mobile World Congress 2008

The Mobile World Congress (MWC) 2008 in Barcelona was a great event. Thanks to Andy Abramson and the Nokia Blog relations program I met a lot of interesting fellow bloggers. My pal Alec Saunders was so nice to make a listing of the people we met:

Some of the great people and bloggers I bumped into at the show include Stowe Boyd, Darla Mack, Jonathan Greene, Matt Miller, Alan Reiter, Oliver Starr, Bill Tam, Lubna Dajani (get that blog going, Lubna!), Esme Vos, Martin Geddes, Dean Bubley, Xen Mendelsohn, Martyn Davies, Jonathan Zar, Loren Feldman (and it was me who mistook him for Ze Frank), Markus Goebel, Jeb Brilliant, James Body, Florian Seroussi, Daniel Appelquist and of course Pat Phelan. You can read more about the show on any of their blogs.

I would like to thank especially Martyn Davies from the VOIPSA blog. He gave me great hints to prepare my interview with Fring's CEO Avi Shechter - who was so kind to say that he is a regular reader of this blog, although he doesn't always share my opinion. Also the Cellity founders Sarik Weber and Tim von Törne outed themselves as regular followers. And Michael Poppler, European region sales manager of VoIP solution provider GIPS, even jumped out of his booth when he recognized my name on the MWC badge, saying that he always wanted to get to know me.

Thank you very much for this feedback!

It was the first time in a long period that I left my cave in Berlin from where I maintain contact to the IT industry largely by internet and phone. The next opportunity to meet me is a the CeBIT trade fair in Hannover. Needless to say that I brought lots of exclusive information back home from Barcelona. I will cover it in my next blog entries. Great changes are coming and some of the most pestering problems in mobile VoIP will be solved soon. (Not only that Packet8 made their MobileTalk a free product as I always advocated.) Some companies have have discovered new business models or changed their technology, but didn't announce it yet.

Most fun was my interview with Qik's co-founder Bhaskar Roy. His company is so hot that one venture capitalist even asked me to convince Bhaskar that he wants to do Qik's second round of funding. Qik should turn down all other offers. That's certainly a great way of living: Being haunted by rich people who compete to give you their money. But Qik deserves it. You just switch on the Nokia N95 and yet your face is broadcasted on the internet. Just look at the morons on Qik's start page who still don't realize that they are online and everyone can see them! My tip from Bhaskar: Dial zero and your broadcast switches immediately into privacy mode. Too sad that my Qik interview with Cellity just disappeared. Although Bhaskar had said that I could do it in offline mode and it would be uploaded automatically from the phone the next time I connected to Qik over Wifi.

To make money from mobile VoIP, companies have to accept certain realities

Jon Arnold has updated his very interesting portal website IP Convergence TV. This time I also wrote a guest opinion, because to make money from mobile VoIP companies have to accept certain realities: "WiFi isn't everywhere and callback costs double".

I love the mobile use of VoIP but I still find it quite uncomfortable. That's what I point out. Especially annoying is how Skype, Fring, Truphone and other SIP based VoIP services get blocked by German 3G providers. Sorry, Dean Bubley from Disruptive Analysys! The reality looks much darker for VoIPo3G than you predict for the future. (But thanks for your regular Google ads "3G mobile Voice over IP. Analyst report: is it a threat to carriers? Or a future opportunity?". I better put a direct link to your website.)

Mobile VoIP over Wifi works only at home or in the office where I don't need it. So in my guest opinion I advocate intelligent cell phone software which automatically completes calls as callback, callthrough, Vo3G or VoWifi while the user doesn't even notice. I have already installed an example software on a Nokia E61.

Maybe if more and more people use these options, Dean's dream will come true. If everyone uses only mobile callthrough, triggered by intelligent software on the handset, the mobile network operators cannot charge any other items than the tariff's included minutes for local calls. Their voice legacy cell phone networks would become dumb pipes into the internet, the way we already see it with the 3Skypephone or iSkoot, Ringfree, Mobivox, Jajah Direct, Sipbroker, Tpad, Rebtel, Mobiletalk, etc. If mobile operators wanted to charge for international calls at all, they would have to embrace VoIPo3G and could at least charge for data, the way Dean predicts it.

But until this comes true, the mobile VoIP companies should attack the incumbents with better callthrough options, to take more and more cell phone calls out of the traditional networks and into IP. Read the full text for further explanations!

Why there never will be a hosted-Skype-to-SIP

Phonegnome's David Beckemeyer has a great post, explaining why my dream of a "hosted-Skype-to-SIP" will not come true, as long as Skype doesn't publish its interface.

So don't blame the operators and service providers - blame the cause of the situation SKYPE! Skype needs to provide "data center" solutions if you expect more operators and service providers to deploy "hosted Skype" services.

Thanks for explaining how many hacks are necessary at Fring and Mobivox to build bridges to Skype. And please don't try to call me on Skype! I am most probably not connected.

Read David's post.

GTalk2VoIP starts callback

Yesterday my virtual buddy service@gtalk2voip.com started to chat me automatically when I had my GMail open. He told me about a great new service that's possible now with GTalk2VoIP: Callback.

All users of Jabber based IM chat, Google Talk, MSN/Live Messenger or Yahoo! Messenger can use GTalk2VoIP service to initiate VoIP calls using CALLBACK technique. This means, our system can make VoIP call to your phone (mobile or landline), then make a call to your destination and merge two calls (legs). Callback is initiated by a single IM message sent to service@gtalk2voip.com.

Just talk to the robot! Use your instant messenger to say "CALLBACK +1-111-2223344 +1-555-6667788" to the service@gtalk2voip.com buddy. This will initiate a call to your phone number +1-111-2223344, then to your destination +1-555-6667788. It even works on your mobile phone if you use Fring or the mobile version of Gizmo Project.

The calls cost the normal GTalk2VoIP rates or the rates of your own SIP provider which you can also use at GTalk2VoIP. Each call leg is billed separately, so if both legs are phone numbers the final cost will "double". But normally it should be no problem to use your Fring to start a free call between your friends landline and the fixed line telephone next to you.

This seems much faster and easier than Jajah to me.

No Truphone over Fring anymore

With its new version 3.0 Truphone has not only added new features, they have also closed a security breach. I realized it today. Until the latest version there existed a trick to retrieve Truphone's SIP password and then install it on every other SIP device. This was quite convenient for people who don't want to use Wifi continuously on their Nokia cell phones because it drains the battery.

These people could just install Truphone on their softphone or ATA to receive phone calls with their Truphone number. UK users of a Nokia N95 with crippled VoIP could avoid their problems by using Truphone together with the 3rd party software Fring. I guess Truphone was not too happy with that since one of their revenue streams is call forward: When you are outside a Wifi area Truphone forwards incoming calls on your cost to your cell phone number and takes its share from these costs. Unless you have a US mobile phone number, then the call forward is free.

If you have installed Truphone 3.0 it's now impossible to find your SIP password on your mobile phone. At least unless another hacker finds another way to retrieve it. I can't reveal how it had been done before, since there are still users of version 2.0 who could make use of it and therewith violate Truphone's terms and conditions:

Compatible Handset

You may only use the software and service with compatible handsets or devices identified on our website www.truphone.com. You must check the list of handsets on the Truphone website to ensure You download the correct software for your phone. Truphone is not liable if You do not have a compatible handset or if You have downloaded the wrong version of the software for your handset. Truphone reserve the right to terminate this agreement should you be using the Truphone service with a handset or device that is not identified on the website as compatible.

I suppose that call forward and interconnection fees are Truphone's way to fund their recently anncounced free mobile calls to 40 countries around the world for the rest of the year. That's why they are so happy to have won the court injunction against T-Mobile which had blocked calls to Truphone's new numbers. More insight on the issue and how Truphone earns from calls to it's numbers can be found here.

My answer to Jeff Pulver's "Call for More Innovation in Voice Services"

Jeff Pulver and Ken Camp are bored from what they've seen in VoIP lately. That's why Jeff startet a "challenge for innovative disruptors with regards to the voice applications industry":

Think about presence and voice and instant messaging, take a look at the APIs of twitter and Facebook and pitch me on the service that you want to create. Those who get my attention might end up with the early-early seed capital needed to turn their dream into a reality.

So what could that be? Jeff doesn’t want to hear about a service that's simply a variation on Call Forwarding and/or Voicemail. It has to be something really different. Something cool. Something that truly helps to redefine communications.

I am really courious to see the winner of this competition. I don't know why Jeff is so excited about Twitter and Facebook. To me these applications are mostly a waste of time. But what I would love to have is a "Hosted Fring with Grandcentral's filter rules and international mobile callforward over GSM".

What does that mean?

I like Fring because it connects me with just one program to my contacts at Skype, MSN messenger and Google Talk. Lately it also works as a VoIP client. But only on my Nokia mobile phone!

Why isn't there a website that does the same like Fring? Why isn't Fring a hosted service? I would love to leave my login data for all these services on their website and connect to it over SIP from my ATA. A kind of Voxalot, but extended with Skype, MSN messenger and Google Talk.

Whenever somebody contacts me, my phone should ring. Outgoing calls to Skype, MSN, Google or phone numbers should also be made with my normal phone. The server would decide automatically how to connect the call, because it has call rules for that - like Voxalot has.

Incoming calls would be filtered like at Grandcentral. Annoying people could only leave a voicemail and good friends could ring my phone day and night.

This service should of course not only work over an ATA but also over the mobile phone network. Internationally! There are more and more international MVNOs slashing roaming charges and giving local fixed line numbers to mobile phones. This means they already have an own SIP infrastructure and GSM gateways in every country. If they can give me a local fixed line number in a country, they can also deliver cheaply the described calls from Skype, MSN, Google and my home VoIP providers over GSM.

Outgoing calls should be done the Nimbuzz way:

Call your IM buddies on their mobile or on their PC. At the cost of a local call, worldwide. No credits needed.

A small application on my mobile phone would always know which cheap number to call in every country to connect to the described network.

I am sure, that the despicted layout is possible. The guys at Fring, Grandcentral, Gtalk2VoIP, Skip2PBX and Roam4Free have already pieces of it in their hands.

Comprehensive VoIP overview in San Francisco Chronicle

The San Francisco Chronicle has a nice comprehensive overview about some of the most importantVoIP companies and minute stealers:

Numbers are adding up for international callers
Internet services help to cut consumers' phone bills
Thursday, June 21, 2007

They cover Jajah, Rebtel, Talkplus, Truphone, EQO Mobile, Mino Wireless and iSkoot. I would have liked to read also about Gizmo Project, Mobivox, Fring or Mobiboo. But then again the article appeared on page C - 1 of the San Francisco Chronicle, and paper isn't endless.

Mobile incumbents agree to lock down alternative VoIP providers

The air is getting even thinner for mobile VoIP companies like Truphone or Wifimobile, tells The Register. The Open Mobile Terminal Alliance, a organisation of big mobile operators like Orange, Vodafone, T-Mobile and 3 has published a guidance for network operators and handset manufacturers on provisioning and maintaining VoIP settings on new handsets. It covers only the usage of pre-installed VoIP clients on handsets, such as that used by Truphone or Wifimobile. Applications which are downloaded later, like Fring or Vyke, go free.

According to the OMTP specifications, operators are entitled to remove or lock down VoIP applications on subsidised handsets, but they must provide the ability to remove that lock when the contract period expires, just as they now will release a handset to be used on another network (SIM lock).

Bad luck for some independent mobile VoIP providers, as the incumbents agree on that the initial VoIP settings should be securely protected in the terminal, and can only be changed by the operator. When the service contract comes to an end, the customer can request the provider to unlock the Terminal’s VoIP settings and associate the pre-installed voice applications with alternative VoIP service providers.

This means in most cases: No Truphone or Wifimobile in the first two years of a contract.

Much better off are independent mobile VoIP companies which install their own applications, such as Skype, Fring, Gizmo Project, Jajah, iSkoot, Nimbuzz or Yeigo. The customer may be able to install third-party applications (Java or other Terminal OS applications) that offer VoIP calling using third-party VoIP providers. The only VoIP applications that are forced to use the operator’s settings are those that were pre-installed on the Terminal, and only during the term of the contract that the Terminal was supplied with.

The mobile phone users must be informed that VoIP has been locked or disabled. So the removal of menu items, in the way that Vodafone and Orange crippled their Nokia N95, wouldn't be allowed. The Register states that the guidance is not binding to the member companies. But as so many network operators were involved in writing, it's surely what we will see next on the entire European or world market.

Let's see if that's acceptable to regulators such as UK's Ofcom and what e. g. Truphone will do. Their new software Truphone 3.0 is so feature rich and has presence functions so that it seems quite similar to the mentioned "alternative VoIP applications" to me. If Truphone 4.0 packed it all in the software, instead of using Nokias underlying SIP functions, they would be out of trouble.

But then Truphone would suck as much battery as Fring does.


UPDATE:

I got an email from Wifimobile's John O'Prey. He says that his company is NOT affected. "This is not the case as our client is a stand alone application which can be installed. I would be most grateful if you could kindly correct this."

Sorry for that!

T-Mobile UK vs. Truphone: Just the 1st of Hydra's heads

T-Mobile UK is blocking calls to mobile VoIP start-up Truphone. That's a serious issue which caused interesting discussions and points of view. As GigaOM puts it: "CellCarriers fear mobile VoIP planet". That's more or less how I see it as well.

After the fixed line carriers got shaken up by VoIP now it's the mobiles' turn. T-Mobile UK tries to defend its well established business. Maybe Truphone shouldn't have said that they now support VoIP over 3G. It's the old fear of the traditional mobile carriers and one of the main reasons why they kept the mobile data rates sky high in the last years: To loose their comfortable voice revenues.

Rebtel's CEO Hjalmar Windbladh explained to me not so long ago that mobile carries pay only 0.8 Cent to connect a call between Germany and China. But they charge 1 Euro or more from the customer, depending on his contract. These big margins would get lost with VoIP over 3G and maybe that's the reason why T-Mobile UK wants to dry out its competition before it gets too strong.

But this is like trying to cut all of Hydra's heads. It's not only Truphone which is offering VoIP over 3G and over Wifi. It's also Fring, Wifimobile, Mobiboo, Yeigo, aql and thousands of other companies worldwide. In fact every SIP based VoIP provider can do a quite similar job like Truphone. It makes no difference if you install your SIP login data into a mobile phone or an ATA or a soft phone.

I especially like it to have my fixed line home number ring on my mobile phone. For that I use Wifi or a call forward over GSM. Outgoing calls are nearly free or free via calltrough or Wifi.

Just like at Truphone.

Sipgate is blocking Voxalot but not Fring. That's not fair!

Sipgate is one of the best quality VoIP providers I know for Germany, Austria and the UK. They give free inbound numbers and, with rare exceptions, they always work. Last friday they were down for a half hour, but this was no big problem.

Until people started to realize that Sipgate behaves strangely since then. As I tested Sipgate is blocking all the free "always connected" web based PBXes I know:Voxalot, PBXes.com and simplyConnect. That's really annoying since those websites do a great job. You can deposit there all your login data for the many SIP accounts you got from different companies. Then you need only one account, for example Voxalot's, to receive phone calls to all your different VoIP numbers on one device. Also you can define dial plans for least cost routing. Then Voxalot uses for instance provider A for phone calls to country number 1 and provider B for country number 2, always taking advantage of the cheapest connection.

Thats nice for VoIP devices which can hold only one SIP account, such as certain mobile phones or the Fring software, which recently got very important for mobile VoIP users in Great Britain. With Fring you can avoid the problem that for Orange UK and Vodaphone UK are blocking VoIP on the brand new Nokia N95 mobile phone. As an external Symbian program Frings makes SIP calls possible on these crippled N95, but holds only one SIP account. Which should be Voxalot or something similar if you have different providers. I already use more than 20 VoIP providers.

It seems that Sipgate doesn't like the described least cost routing, since their prices aren't cheap compared with other providers. Poor Sipgate! Mean Germans use them only to receive calls on Sipgate's free incoming numbers, but for outgoing calls they use free VoIP services from companies like Betamax. Nothing is cheaper than free, and even Sipgate's flatrate for Europe cannot compete with it. Maybe Sipgate did not like it that the their Voice Mail answered all calls to my dozens of different VoIP accounts that I have installed at Voxalot. Even if you called my FWD or Gizmo account the Sipgate Voice Mail kicked in. This was a nice feature since I had to deal with only one Voice Mail box for all my VoIP and fixed line calls.

It seems that Sipgate wants to work like a normal PSTN telco and tries to be as much separated from the SIP world as possible. Only if people use Sipgate for their outgoing phone calls and do not free ride their services they can sponsor the free incoming numbers. I, for instance, use Sipgate's number and Voice Mail yet for years but never paid them any money, since all my outgoing calls go for nearly free over the Betamax company Voipstunt. People from England do the same, as you can read in Voxalot's forum.

I suppose that Sipgate prefers to be their clients only VoIP provider and therefore it blocks more and more interoperability options. This started already months ago when they began to block phone calls from other VoIP providers to their SIP adresses. SIP to SIP is normally free. But now the only option is to call the phone number of a Sipgate user, which is only free within the Sipgate network or for calls from their spare peering partners.

The hottest discussion about the PBX blocking I found in Voxalot's forum. Sipgate clients are disgruntled that they cannot use the service with Voxalot anymore and give tips about alternative providers. One user even threatened the Sipgate support to cancel his account and got surprised that they did not try to hold him back, but explained in a polite way how to do it.

Sipgate's official explication is the following:

login details must not be given to 3rd parties. the provider mentioned above (note: voxalot is ment) attracted attention due to nonserious business practices. for our customers safety we try to remedy potential abuse through this corporation.

Other Voxalot clients got a clearer answer from the Sipgate support:

This is a security problem.

Later it got more personally against Voxalot:

Poor Voxalot! What did they do? How should the company behave in this situation?

Voxalot's support worker Martin says that he "would be interested to know if this is an across the board "security rule" or if simply Voxalot was "singled out".....". An interesting question, because Fring seems to work very well with Sipgate, although Fring also requires the user to give his Sipgate login details to a 3rd party.

Why isn't Sipgate blocking Fring as well?

In fact this is a general problem: With every time more services moving into the web people have to provide every time more secret login data to 3rd parties. It reminds me of a former post that I wrote in april in Voxalot's forum, "Theoretically Voxalot could steal all our VoIP minutes".

But it's not only Voxalot. It's also PBXes.com, simplyConnect, Fring, Barablu, Nimbuzz, Talkster, Mobivox, Iskoot, Skip2PBX,... Dozens of companies are in the same situation. There has to be a more intelligent solution than just blocking Voxalot. What's missing is a secure way to share login data.

Maybe OpenID is the answer?



CORRECTION: Sipgate now at least seems to work OK with PBXes.

Why Truphone is weeping so much over the crippled Nokia N95

At Truphone they are still howling about the crippled Nokia N95 that Vodafone and Orange are selling in the UK.

They claim that the move is an attempt by mobile operators to stop open competition for mobile internet services and to lock customers into their services. But at the same time we learn that stand-alone VoIP applications, such as Fring, still work on the N95.

And maybe that is the real reason for their weeping.

Truphone itself is a closed system. And for that reason it is the world's only SIP based VoIP provider that doesn't work with Fring. Other providers can circumvent the N95 problem by recommending their clients to use Fring.

But Truphone works only on Nokia cell phones and the only way for installation is the Truphone wizard program. It saves all the necessary login data for Truphone automatically on your phone, which on the first sight seems very comfortable. But later, when you want to review the SIP settings, you realize that you can't see your password for Truphone's proxy and registrar server. Instead you see only ****.

This was once a clever move to prevent that people install Truphone on other devices, such as ATAs or softphones. Truphone lives in a large parts from the fees that people have to pay when they aren't in a Wi-Fi network. In this case many users get their incoming calls forwarded over the traditional mobile network to their cell phone number, which costs. Furthermore the Truphone numbers in the UK are special mobile phone numbers. To call them is quite pricey and Truphone takes its share from the incoming calls. (I already found a workaround for that.)

By trying to save these competitive advantages over the other VoIP providers Truphone shot itself in the foot. Now they are the only company whose VoIP service doesn't run on the coolest Nokia phone ever.

And that in their home country UK.

Fring is so great on GPRS!

Today one of my favourite mobile phone applications, Fring, got kicked by some VoIP experts. It was a classical blog circle, where someone throws a bone in the ring and the others can't hold back from chewing it through as well.

The starter was David Beckemeyer, alias Mr Blog. He is CEO of TelEvolution, the producer of the PhoneGnome, which connects normal phones to VoIP and to Skype. He got quoted by Andy Abramson, daily blogger and CEO of Comunicano, a Californian public relations firm. Another piece came from iotum's CEO Alec Saunders.

The circle of argumentation reminded me of what Thomas Anglero, yet another big VoIP expert, said in december:

As I read through the VoIP blogs, it is clear that VoIP bloggers and the VoIP community itself, does not allow for just anyone to become a member. VoIP bloggers talk about each other (over-and-over), and the VoIP development community only respects those who have done something so glorious before in code. This mindset will kill our industry.

Although blogs are open for comments and trackbacks, the matter of VoIP still seems so difficult to understand (or is it so boring?) that sometimes near incestual relations between blog posts arise. Today everyone seemed to agree on that Fring sucks. Which I see totally different. That's why I feel the need to comment it in my blog as well.

Andy Abramson said:

I think Fring is cool, but I question its utility, especially in GPRS and even EDGE markets where the audio sounds so muddy that its not what you would want to use for a business call.

And David Beckemeyer:

Like many other cell phone users in the US, I have GPRS data service rather than a true 3G data service with my carrier. My first experiences with Fring over GPRS were not very good.

Alec Saunders followed up by criticizing Fring's monetization strategy, arguing that Fring might have some cool features but the guys don't know how to make money with them.

I think they all have lost the point: Fring is the best application to control nearly all important chat and VoIP applications together in just one program. In Europe the mobile networks are as fast as DSL connections. Fring's voice quality is no big deal anymore.

Also you have to see that Fring is much more than a VoIP client. In fact you don't need an extra VoIP client on Wifi enabled mobile phone. The congfiguration of a Nokia E61 is fairly easy and there are loads of web pages which explain how to do it.

The really cool feature is that Fring is a chat client for MSN messenger, Google Talk and Skype at the same time. It is the only way to bring Skype on a Symbian phone and on my Wifi the Skype calls sound great. Isn't that marvelous? I even tried in on GPRS. The voice is understandable. Only the delay is too long.

I use Fring to chat with my buddies. We send text messages instead of SMS. One SMS costs me 15 Euro Cent. But for the same price I can send thousands of chat text messages, since my no frills mobile operator Simyo charges only 24 Euro Cent for 1 MB. Overall I will have to pay 2 Euros for GPRS this month.

Thanks to Fring.

More tricks for free phone calls

Yesterday I told under the headline „Why mobile and landline phone calls will soon be free“ my outlook on the future of telecommunications. I am sure that per minute charges for landline and mobile phone calls will soon be a thing of the past. Even a 29 dollar monthly flatrate for all calls will seem too expensive. But not because the companies change their business models. It's the clients who find ways to circumvent the paid networks. They leverage their phone costs by using the SIP standard which can be seen as a Pandora's box to the industry.

Today I want to show you some other examples how I would do it. I'll also try to explain how the companies try to avoid these tricks. Skype and Truphone for instance try to stay out of the rat race by avoiding to implement the whole functionality of the SIP standard. Skype more than Truphone, obviously. Rebtel tries to tie up their clients to pay 1 Dollar a week for their incoming numbers. Jajah wants you to deposit at least 5 dollars on your account to charge you for their callback service. But they all can be beaten.


Connect Skype to a normal phone:

Skype relies on its own closed communication standard and until now there were no easy ways to use Skype on your normal phone. But maybe these days are over.

The VoSKY Exchange from abpTECH alleges to be the world's first product to seamlessly bridge an existing PBX to the Skype network. It adds four Skype lines to your PBX, and extends the benefit of Skype to every extension in your office.

At CeBIT the Italian company PCService presented in march their Linux software Skip2PBX, which serves as an addition to a company's existing PBX. Installed on a Linux machine, which can also be virtual, it controls up to 30 Skype accounts at one time, using different sessions of the Skype program. When a Skype call arrives it's being redirected to a phone. The Users can call their Skype contacts for free by using short numbers on their phone.

But the easiest way is certainly to use Fring on a mobile phone. Why hassle with the PBX when there is a phone software that communicates with all kind of messengers and SIP phone networks? Fring works on Wifi and 3G.


Get a cheap incoming phone number for Truphone:

Truphone has another interesting way to assure their income. They give free calls to 40 countries worldwide until end of June, but maybe this special offer will last forever. It's not only a marketing gag, they just have another source of income. The Truphone numbers in the UK are mobile phone numbers. To call them is quite pricey and Truphone takes its share from the incoming calls, as a Truphone network engineer affirms.

But there is an easy way to avoid these costs:

Install Sipgate as a second SIP provider in your mobile phone. So people can call you on your free Sipgate landline number. You can even set up a call forward from the Sipgate number. Just install Sipgate on Voxalot and make a call forward to your Truphone SIP address which has the form 447624XXXXXX@truphone.com. Your friends can call you always on your Sipgate number, but poor Truphone (which you will probably use for the free outbound calls) will not earn on the inbound leg from PSTN anymore.

Truphone always tried to prevent this kind of tweaking by not showing to their costumers their own SIP password. Truphone's software leaves it encrypted on the Nokia mobile phone to prevent that people use the service on other devices, circumventing the Truphone network. So do the Sipgate workaround! Calls between Sipgate and their partner networks are free, that's understood.


Get lots of inbound numbers like at Rebtel:

One business of Rebtel is to give you local incoming phone numbers in many countries and charge a dollar a week for that. But why should you pay when there are free incoming numbers? I, for instance, have dozens of SIP accounts with their respective inbound numbers from different countries concentrated at Voxalot. No matter which number you call, they all ring on the same phone. The thing gets even more funny because my Voxalot account works with Sipbroker and Tpad. They have inbound number in nearly every country of the world. You can call them at a local rate, dial the account number and my phone will ring.


Free Jajah like web callback:

Voxalot even has a Jajah like web callback. But other than Jajah these calls can cost you nothing if you use free VoIP providers on both legs of the call. There is also a version for cell phones at mobile.voxalot.com which costs nearly nothing for the mobile data. Enjoy your free calls!


Of course the described services also work on mobile phones outside Wifi, using an IP PBX with GSM SIM cards as 4S newcom offers.

Why I use about 20 different VoIP providers

At GigaOM there is an interesting survey going on under the title "Does your house VoIP?". Om Malik asks:

Regardless, time to ask the community what kind of a VoIP users are you? Cable kind, or someone who uses soft clients or do have still doing the Vonage styled ATA-based VoIP calling?

This cuestions finally made me get a general idea about all the services I use. And, god, it's a lot of them!

Actually I am using 20 VoIP accounts, out of couriosity and because of the different services they offer. But maybe I am subscribed to even more, but just forgot it. My goal is to make free calls and use arbitrage possibilities between the different VoIP services. I use the different VoIP providers on my desk phone that's connected to the Fritz!Box fon ATA and on my mobile phone, Nokia E61, that can hold several SIP accounts. Also I use Fring on the E61, because it can hold my accounts on Skype, MSN messenger, Google Talk and also one SIP account.

Here is why I use so many different services:

Voipstunt: For free or super cheap calls worldwide. This services I use most. It's installed on my desk phone and on my mobile phone, Nokia E61. So I can make free calls from Wifi hotspots.

Sipgate: Is use Sipgate as an answering machine. Incoming calls to my ATA are forwarded for free to the Sipgate mailbox if not answered in 30 seconds. For that purpose we have two Sipgate accounts at home.

Tpad: Because of their BreakIn numbers worldwide. My friends from Peru can call me so in Berlin for the cost of a local call without having a computer.

Truphone: To check it out on my mobile phone and because of their new offer that gives me landlines nearly worldwide for free in the next two months.

Several services for testing purposes and out of couriosity: GMX, Voipbuster, FWD, dus.net, Sip2sip.info, Ekiga.net, Openwengo, iptel.org, Rebtel, 4S newcom ...

Voxalot: Every time my Fritz!Box fon ATA gets too full, because it can only hold 10 VoIP accounts, I move the one I don't use to call out anymore to Voxalot. This service works like an ATA in the net: It's logged in to the VoIP services I don't use so much anymore. So I can keep them and receive calls on their SIP addresses or phone numbers. For instance if somebody calls my unused Gizmo account (I have several of them) my Voxalot account in my Fritz!Box fon ATA rings.

Gizmocall: I have set up a special web link to my address at Gizmo Project. So people can call me unlimitedly from a web page.

Ageet: That's probably the world's smallest PBX. It works as a Activex plugin in Internet Explorer and has a link from my website. If people open this page the PBX loads and they can call me from their browser. This was really cool until I discovered Gizmocall one week later.

The large quantity of the services I use is not so much a sign that I might be tech crazy. It's just an indication of how much the VoIP sector is still evolving. The industry consist of thousands of different companies that offer basically the same: Cheap phone calls over the internet. But if you look closer you see that they differ in the added services: cheap break in numbers, calls from a website, use the old PSTN number as VoIP number, administrate your other VoIP accounts,...

So probably I will have soon 30 VoIP providers. For instance I am interested in a Peruvian VoIP number that my friends in Lima can call for price of a local call. Tpad is already doing a good job with their callin number and the extension. But sometimes this does not work and a real Peruvian phone number would be much more elegant. But still the Peruvian VoIP market is underdeveloped and these numbers are too expensive to me.
