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

[Daniel-Constantin Mierla]

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.

Module's documentation:

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
