Missing rtcp-mux attribute on final response when to-tag changes

[rhondahollis]

Hi Richard, I'm wondering if there was any follow up on this issue where the final response comes in with a different tag from what was on the 18x, and the rtcp-mux attribute does not get added to the SDP on the final response.
#1126

I have this same issue in my environment, so I'm looking for a way to resolve this. I've tested with rtpengine builds mr10.5.1.3 and mr11.0.1.6, and the behavior is the same on both.

We still don't support unsolicited to-tags in multiple answers, so no. You can work around it by pretending that there is only one to-tag.

Closing this as the other topic is still open.
