Hi,

I have set up a direct SIP trunk between our Mitel PBX and our Lync Server.

Calls from Lync to mitel work ok, and inbound, calls from the Mitel box to the Lync does npt work.

The problem I am having, is that i can see the call reach the the Lync and tries to find the destination with no success, after the timeout, i am getting a busy tone, call session set to both 0 & 90 with the same result.
