In order to send the MSC's RTP endpoint IP address+port in the initial SDP, move the MGCP CRCX up to an earlier point in the sequence of establishing a voice call. Update the voice call sequence chart to show the effects. Though the semantic change is rather simple, the patch is rather huge -- things have to happen in a different order, and async waits have to happen at different times. The new codec filter helps to carry codec resolution information across the newly arranged code paths. Related: SYS#5066 Change-Id: Ie433db1ba0c46d4b97538a969233c155cefac21c
