asterisk users - Jun 2006 - Conferencing with multiple servers

Hi,

   I am trying to join 2 asterisk servers together using a sip channel.
This is so, if a user joins a conference on box A and another user
joins a conference on box B, providing they are in the same conference
room, the two conferences are joined via the sip channel. We only want
to join the conferences together if they have users in them and we
don't want to point all the conferences to one server as we would like
to try to balance the load a bit.

   Any ideas on how to impliment this?

    With thanks,

    Tim

Nope, never tried but I guess you could use something like app_bridge to
do it. Check out http://bugs.digium.com/view.php?id=5841
Maybe you can also do it with the manager interface (search for AMI on
voip-info.org). Good luck and let us know how it goes.

Patrick

This is a general problem with the 'enterprise grade' aspects of
Asterisk. As far as I know, there is no way to distribute applications (eg:
Queue, Meetme etc) between multiple Asterisk systems. You really need to run the
applications that will serve a common set of phones on the same Asterisk system,
and then fail over to a secondary if necessary.
