[edit] Features

Jabbin allows XMPP instant messaging and free voice calls. It is cross-platform with versions for Linux and Windows. A port to Mac OS X is in development.

[edit] Under the hood

The program is based on the Psi XMPP client. Both are written in C++ and use the cross-platform Qt library to provide their user interface. Version 3.3.x of Qt is used so it's not very easy to build Jabbin on Windows using only open-source components. Either unofficial (but legal) Windows port for Qt 3.3.x/X11 needs to be used or Qt 3.3.x commercial license required)

Like Psi, Jabbin uses the XMPP communication protocol, but uses the libjingle library for peer-to-peer VoIP connections. Jabbin incorporates the libjingle support from Psi (where it was still considered experimental) with additional Windows support and uses the free voice codec Speex.

[edit] History

The first version, 1.0, was released in December 2005, based on the development Psi 0.10. The telephone connections were made via the TINS extension to XMPP.

Since version 2.0, VoIP support was backported from Psi and extended to work on Windows. It uses the libjingle library from Google, but does not (despite the confusing name) implement the Jingle protocol from the XMPP Standards Foundation. The support for this protocol replaced TINS.

For version 3, Jabbin plans to support videophone calls.

Current (28.05.2008) SVN arleady has many important fixes and additions like fix for Service Discovery(with was broken in betas of 2.0),workable and workable support for Jabbin->PSTN calling (this feature require server-side support, it works with OpenFire+Asterisk pair as server, which is used on JabberOut.com(currently in beta)).

[edit] Oddities

Update (April 9 2008): Now you will be redirected to a commercial web page of "Telecom64". The last version of the software (2006-07-21) is still available at Sourceforge.

Update (May 28 2008): VoIP->PSTN calls are not reliable in the presence of Symmetric NATs and/or UDP blocking (VoIP module currently doesn't auto-fallback to TCP)
