Asterisk can connect as a client or component to a XMPP server. XMPP
components are typically used as gateways between XMPP and other IM
services such as MSN or Yahoo.

You can connect Asterisk to GoogleTalk's XMPP network as a client
only, which will therefore be accessible through a presence
subscription mechanism just like a usual client.

On the other hand, you can connect Asterisk as a component to your
locally administered XMPP server, for example. A 'service discovery'
request to the server will show the Asterisk server as being

Asterisk can be used to call Gtalk users from SIP phones, and vice
versa. Configuration examples are given here :
The call configuration is handled in the Dialplan in that case.

If you need to place a call from a XMPP client to a SIP URI, you'll
also have to find a client that's able to to so. I know that
GoogleTalk and Jabbin both speak XMPP + Gtalk. However, the GoogleTalk
client's user interface does not allow you to place a call to anything
but another XMPP client from your buddy list, without offering the
ability to enter either a SIP URI or phone number. A possible
workaround was available here :

As for Jingle, Asterisk tries to follow the latest set of
specifications (code only available from SVN trunk), which are not
completed yet.
