*
* The Asterisk Jabber Interface, AJI, publishes an API for
* modules to use jabber communication. res_jabber.c implements
* a Jabber client and a component that can connect as a service
* to Jabber servers.
*
* \section External dependencies
* AJI use the IKSEMEL library found at http://iksemel.jabberstudio.org/
