Trixbox main server of my topology

Hi all,

I hope that someone can help me with this issue cos I´m not a very good voip technical person though I´m trying it :)

I´m trying to set my trixbox PBX as the main server of my topology voip communication, I´ve connected differents servers to Trixbox to try to comunicate all these servers trough trixbox.

I have connected with a SIP trunk an voip server to my Trixbox server and theirs clients calls to the trixbox clients are working fine, so the sip trunk should be fine.

I also have connected another trunk from another server to my trixbox but this trunk is an ooh323 trunk. The communication between clients of this server and trixbox´s server is working fine too, so I guess that the ooh323 trunk is working fine too.

The problem start when I try to call between clients servers going trough the trixbox cos the call never work and I got a voice message which says "goddbye"

that´s my topology.

Server 1 ------ Trixbox ------- Server2

trixbox to server 2 work ok by oo323
trixbox to server 1 work ok by sip
server1 to server 2 don´t work.

Thanks
