Detailed Description

XMPP client and component module.

Author

Joshua Colp jcolp.nosp@m.@dig.nosp@m.ium.c.nosp@m.om

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.

Load the module.

Module loading including tests for configuration or dependencies. This function can return AST_MODULE_LOAD_FAILURE, AST_MODULE_LOAD_DECLINE, or AST_MODULE_LOAD_SUCCESS. If a dependency or environment variable fails tests return AST_MODULE_LOAD_FAILURE. If the module can not load the configuration file or other non-critical problem return AST_MODULE_LOAD_DECLINE. On success return AST_MODULE_LOAD_SUCCESS.
