Talkonaut 4.0 native Symbian S60 edition released

The GTalk2VoIP dev team just released their VoIP+chat application for Symbian S60 phones that runs as a native (.sis file) application. I should stress that several Nokia smart phones come with a SIP stack, however they are limited to WiFi use only and won't work over your cellular network. You can thank the carriers for that one. Talkonaut on the other hand is not bound to WiFi only, allowing you to make calls over GPRS, EDGE, 3G or WiFi. Talkonaut has essentially developed their own VoIP SIP stack that allows Talkonaut users to make voice calls over most data connections your mobile phone might have, such as GPRS, EDGE, 3G and WiFi. The application also sports the ability to make free VoIP calls to Google Talk users, to SIP phones, to MSN, Yahoo, AIM and ICQ voice capable IM clients. I believe you can even chat with MSN Messenger, Yahoo, AIM, and ICQ users.

Here's a list of the new features in the 4th release according to the release:

- Talkonaut 4.0 was entirely rewritten in C/C++ and now runs on Symbian S60 3rd edition based Nokia smart-phones. Moving from Java to native platform allowed to reduce memory usage, improved speed and to add some functionalities that were not previously available for Jave applications, like VoIP, access to file local system (improved file transfer) and interaction with other applications (Web Browser for opening URLs right from chat window).

- Using a set of narrow-band Speex codecs and relying on Jingle Audio extension to XMPP protocol (same as implemented in Google Talk), Talkonaut now brings to the world a very powerful combination of IM chat, Presence and VoIP calls made over data connection.

- Talkonaut 4.0 allows to make free VoIP calls to Google Talk users, to SIP phones, to MSN, Yahoo, AIM and ICQ voice capable IM clients, as well as to other Talkonaut fellows.

- Talkonaut 4.0 allows to receive free calls from SIP phones (or any other VoIP networks), from Google Talk, MSN, Yahoo, AIM and ICQ users.

- Talkonaut 4.0 allows to make cheap VoIP calls to any mobile or landline phone number in the world.

- Talkonaut 4.0 allows to define any number of SIP accounts and use them to make free or cheap calls over third-party VoIP/SIP carriers. A flexible Dialing Plan feature is helpful for choosing routes to destinations between different carriers.

- Talkonaut 4.0 is fully equipped with all the features previously available in J2ME version of Talkonaut 3.0, inherits the same graphical user interface and menu structure.
