Asterisk-IM is a plugin for the Wildfire XMPP server. It connects to your existing Asterisk server using the Asterisk Manager protocol.
Once the Asterisk-IM plugin is installed, IM users are mapped to one or more phone devices in the Wildfire admin console. Once a user has been mapped, their IM presence is linked to the phone so that anytime they are on a call their presence will be set to "on the phone". The user’s IM client will also begin receiving all events supported by Asterisk-IM, such as notification of incoming phone calls. Presence integration will work with any XMPP client, but other features require support for the Asterisk-IM protocol extensions by clients.
