[Users] NEW SIP-to-XMPP (Google Talk/Jabber) gateway

Hello, thanks to Andrea Spirea, a new SIP-to-XMPP gateway was included in OpenSER. There is a new module, XMPP, which enables SIP users to chat with any XMPP user (Google Talk, Jabber) user in the world. The design permits flexibility in configuration and deployments, the new module can at alone as a XMPP server or can work in tandem with a standalone XMPP server (for more complex communication scenarios like TLS ...). Also, the module can be plugged in your main SIP server or can be deployed alone, enabling in a easy manner geographic distribution and redundancy. There is no need of mapping SIP addresses to XMPP addresses, no need to store translation profiles, everything is done in the fly. The conversation will survive to restarts, the session being recovered form the messages. As a result, there is no need of a persistent storage, the footprint is very small, embedding the gateway in small devices should be straightforward. The news is posted here: http://www.openser.org/index.php?option=com_content&task=view&id=56… Module's documentation: http://www.openser.org/docs/modules/1.2.x/xmpp.html Feedback will be very appreciated, the next steps are to enhance the standalone-xmpp-server version of the module with other features of a xmpp server and to add support for presence and voice. Testing and reports are always welcome. Cheers, Daniel
