I am trying to setup Office Communications Server 2007 to play along with
Asterisk (to use Asterisk for outgoing calls, as well as calling desktop
phones).
Calls from OCS to Asterisk or to PSTN via Asterisk (in between OpenSER) works
fine. When I call from Asterisk to OCS, the Communicator rings, but as soon as
I answer the call, the call drops. Weirdly, the other leg (Phone - Asterisk)
still remains active till I actually hangup.
Sip debug shows is below. Interesting item I can see is:
[Sep 30 16:02:58] NOTICE[6424]: chan_sip.c:8027 set_address_from_contact: '' is
not a valid SIP contact (missing sip:) trying to use anyway
[Sep 30 16:02:58] WARNING[6424]: chan_sip.c:8056 set_address_from_contact:
Invalid host name in Contact: (can't resolve in DNS) : ''
list_route: no route
I think the Contact: header is coming empty somehow. Have any of you
experienced any such issues? I am running Asterisk 1.4.19 and OpenSer 1.3.1 (I
also tried with 1.2 of Openser)
Thanks in advance.
