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. On Fri, 13 Jun 2014, Brian Taylor wrote:
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.
