Distribute Asterisk Events using XMPP PubSub

On occasion it is desirable to distribute device state and message waiting indication (MWI) events between Asterisk servers. This can be accomplished by utilizing XMPP PubSub events and a common XMPP server. The Asterisk XMPP clients are configured via either jabber.conf or xmpp.conf .

Note: AstLinux 1.1.3 or later is required
