Opened: Oct 18, 2018 Severity: 3-Major
A spurious error message is logged ("MR SIP: Media flow creation (...) failed due to collision") and media does not flow.
Media does not flow on pinholes for which a collision was detected and reported.
A SIP server responds to an INVITE with both a 183 "Session Progress" and later a "200 OK" for a single SIP call, and both responses contain an SDP with the same media info.
None
No collision is detected or logged when multiple messages with SDP recreate the same flows in the same call.
