Detailed Description

XMPP client and component module.

Author:

Joshua Colp <jcolp@digium.com>

ExtRef:

Iksemel http://code.google.com/p/iksemel/

A reference module for interfacting Asterisk directly as a client or component with an XMPP/Jabber compliant server.

This module is based upon the original res_jabber as done by Matt O'Gorman.
