It's been a long time, but I think we had the same or similar problem
years ago with a similar setup.
Our problem may have been on outbound calls where a Broadworks-connected
IP phone placed a call to the PSTN and the Telica returned a 180 with no
SDP. There was a delay between the 200 OK when the Cisco answered and the
time that RTP setup fully.
There was a setting in the Telica that forced a 183 with SDP back to
Broadworks, which mostly eliminated the problem.
You might be able to do something similar for calls from the Telica to
Broadworks.

We have customers who are reporting that when people call into them that the
beginning of the greeting is not being heard.
It appears that the phones think the call is ready before there is a complete
audio path. We see this the most on calls that come in from the PSTN. Long
distance or toll free calls are the worst.
We have a Broadworks system that uses Lucent 5010 (Telica) switches for the
connections to the PSTN.
The symptom seems to be very similar for all of our PSTN connections, to
multiple carriers.
I'm just curious if anyone has any experience with this problem, or if anyone
has any suggestions to get to the bottom of the issue.
Any assistance or inspiration would be greatly appreciated.
