It's been long time since my last post here on this blog. Anyways, we have a pretty cool news for all VoIP lovers: yesterday we released our genuine SIP soft-phone written in Adobe's Flash. The features are:

1. Nothing to install, no need to register new accounts. Just open and the Flash app will start itself and asking you to sign in into your existing SIP account.

2. Works fine with SIP accounts coming from almost any SIP provider, just make sure you provide proper SIP Proxy address.

3. Works from WinXP, Mac and Linux. There is a possibility it will work on mobiles when Adobe pushes their Flash Player 10 to mobile devices world-wide.

4. Overcomes strict firewalls which block SIP or UDP traffic.

5. Can be used with our GTalk2VoIP infrastructure to make cheap calls through our certified privders/routes.

6. Can be used to receive calls!

On 31th of March 2008 our GTalk2VoIP gatewaying service has adopted a new, and we suppose, very powerful feature: now any VoIM user (I'm bit tired typing in all the messenger names) can buy a real phone number within any of a large list of coutry codes (at the moment 40+ country codes are availabel) right from their personal account page (MYPAGE) and start receiving phone calls right into IM messenger. The calling service is free of charge, but one has to pay monthly and setup fees for the phone numers he or she is subscribing to. Fees vary from $2 a month depending on country code and phone number vendor. The cheapest numbers are available in US/North America country code - $2/month for a phone number in +1-567 area.

Every phone number purchase is provided with 12 hours of testing period during which user can release recently bought phone number and get 100% refund (money back). So we encourage every one to try this new service, even if you won't need it or find it not of sufficient quality you can release your numbers withing 12 hours and get you money returned to your balance. We also want to hear your feedbacks on this service and a list of country codes you think that we are missing.

Talkonaut for Symbian S60, pre-release.

For the last few months we have been working hard on preparing for release of our new and native Talkonaut mobile software for Symbian S60 platform. Although we devoted a lot of time tesing it extensively, there is always a room for a bug. So we thought that you might be interested in helping us with testing process. You may download a pre-release version of new Talkonaut from We expect to hear constructive feedbacks from you, so if you are not ready for "undesirable" features, you better not try it at all :).

Meanwhile, I managed to arrange some time to write a small essay regarding our mobile voip development process and all the experience we got. Here is an excerp:

Since the very start of GTalk2VoIP project early in 2006 we at GTalk2VoIP TEAM had been nursing the idea of creating something very Google Talk like for mobile phones which could be used to make voice calls over GPRS (and WIFI) as simple as it is made in Google Talk: you see a contact of your friend, if he/she is present, you press Call button and you talk. So easy and so powerful, isn’t it ? On the opposite, the mainstream consumer VoIP software (so called soft-phones) was and still is very unfriendly: simply downloading a SIP phone onto your PC won’t make you able to make calls over the internet instantly, you will need to obtain a SIP account, configure it into your soft-phone, define a dozen of other settings like STUN server, dialing schemes depending on your SIP provider, etc, and only after that, if you were lucky enough, you will be able to add your friend’s SIP URI into list of contacts, then call. Of course being able to manage as many settings is very positive feature for a power user, but for an average this kind of mainstream VoIP is very frightening and totally unacceptable. Sure, there are some projects like Gizmo Project (now Gizmo5) which are desperately trying to make things better, but still…

So at that time early in spring of 2006 we came to a thought -- we want all that Google Talk style VoIP on our brand new mobile phones, with all the power of presence and Jabber based IM chat, we want it to be able to run through dominating GPRS/EDGE service of GSM networks as well as through WIFI hotspots, we want it to be easily and automatically switching between available hotspots like any GSM phone switches between towers, we wish it had a Google Talk like user interface. Why ? Because it’s clean, neat and intuitive, there’s nothing obsolete in its design like innumerous features of Yahoo! Messenger, nothing irritating and slowing down like in Live Messenger, and it is not using stone-age protocol like AIM. But most of all we want it to be completely based on open standards...

Everyone is welcome to read the full text from Please, let me know what you think on the subject.

GTalk2VoIP server upgrade

For the last few weeks our small team has been working hard and has successfully performed moving GTalk2VoIP service to a new server platform. The new server is lots more powerful SMP machine which is now located in Mountain View, CA, USA and has alot faster internet connectivity. We expect to see significant increase in performance and service stability, as well as latency reduce resulting in higher voice quality for all calls made through our gtalk2voip service.

New server will also allow us to introduce a number of new services. The most recent service we are planning to run into production is AIM/ICQ/iChat voice support. Expect to see it soon!

Powerful CALLBACK to set up multi-channel voice conferences.

IM initiated callback is now possible with GTalk2VoIP. You can connect any number of the phones, Google Talk, MSN, Yahoo or SIP users into a voice conference by issuing a single IMmessage.

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

It is possible to add more participants into such callback organized calls thus creating a multi-channel voice conferencing calls. We encourage Web 2.0 developers to adopt this technique into their Web services and letting people freely and easily participate in voice chats.

To initiate a callback call, please follow these simple steps:

Step 1. Subscribe to the service in one of the possible ways:
1st Way. Open your GoogleTalk (or any other IM messenger) and invite new recipient whose user id is
2nd Way. Go to the main page of this site and submit your user id by pressing "Invite" button, then accept invitation from

Step 2. Open a chat window to and send it a CALLBACK command using the following syntax:

CALLBACK [phone:gtalk:yahoo:sip:]SourceLeg [phone:gtalk:yahoo:sip:]DestinationLeg [via provider1 provider2 ]

Where, SourceLeg - is your own location, DestinationLeg - is a destination you are calling to, provider1 - is a provider name which will be used to deliver call to SourceLeg, provider2 - is a provider name that is to be used to call to DestinationLeg. If providers are ommited, then the system will implicate the default behaviour to call to each leg, i.e. it will call the best rated provider first (best ASR and ACD), if that fails, it wll call the second rated, and so on.

Each leg can be one of: phone number, Google Talk, MSN, Yahoo or SIP URI. You can use the follow syntax for each of the legs:

  • +XXXXXXXXX or phone:XXXXXXXXX where XXXXXXXXX is a phone number (mobile or landline) in international format,
  • where is some Google Talk user identifier,
  • where is some MSN/Live Messenger user identifier,
  • where is some Yahoo! Messenger user identifier,
  • where is some SIP URI.

Follow-Me feature for voice capable IM clients.

We now have Follow-Me feature. It allows VoIM users to receive incoming SIP calls and forward them to any mobile or landline phone or to any SIP URI. Usage is simple, you just define a phone number you wish calls to be forwarded to. After that, if you do not unswer incoming SIP call within 20 secs it gets forwarded to your Follow-Me number automatically. Same applys if you are off-line. If Follow-Me is not defined, calls are forwarded to Voicemail system.
