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.

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.

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 Tφrne 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.

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!

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.

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.

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.

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.
