[Asterisk-Users] Conferencing with multiple servers

[Wildheart]

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
