Some SBCs will wait for RTP to be sent from an endpoint so it can identify the source IP and port to use for the return RTP.

In my experience allow reinvites / directmedia, etc will cause a short delay in setting up audio.

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.
