Hello Brian

I did not specify this detail because i did not though  this was important a the beginning, but the same domains are installed on freeswitch1 and freeswitch2 and mydomain.org is in fact a DNS SRV record witch point to freeswitch1 and freeswitch2.

When someone on freeswitch1 wan't to call extension@domain, if it's not registered on freeswitch1 (i check using sofia_contact )  i want to forward the call to freeswitch2 and vice versa.

So i think i can't do a this with a original sofia bridge  but it was possible by using sip_invite_to_uri as suggested by Sergey. Now i need to secure it :-)

It's probably possible to use opensips, but it's seems more complex than a pure freeswitch.
