asterisk users - Mar 2011 - Jabber/Jingle to Google users via local XMPP server

Hi all,

All the examples I've come across seem to suggest configuring
jabber.conf/jingle.conf/gtalk.conf for a real Google account.

What about the scenario where the Asterisk server should connect to an
account on a private Jabber server and using Jingle (voice calling over
Jabber)?

e.g. for the domain widgets.com:

- there is a copy of ejabberd running on the same box as Asterisk, and
Asterisk registers to it using the jabber ID asterisk at widgets.com

- DNS is configured so that user at widgets.com can chat to user at gmail.com
(already working, testing with a chat client such as Empathy or Psi)

Google user friend1 at gmail.com wants to make a voice call to
asterisk at widgets.com - is it possible?

For this scenario, is gtalk.conf needed at all?  Is gtalk.conf needed
for any Jabber server, such as the ejabbard instance described above?

Regards,

Daniel
