Hi,

As currently indicated in BUNDLE, and SDP offer for = RTP must contain an rtcp-mux attribute, indicating support of RTP/RTCP mult= iplexing.

However, it is currently optional to include it in t= he SDP answer.

There has been some discussions on whether we should= MANDATE the usage of rtcp-mux whenever BUNDLE is enabled.

Would anyone OBJECT to that?

Regards,

Christer
