Abstract:
SIP Back-to-Back User Agents (B2BUAs) are often envisaged to also be
on the media path, rather than just intercepting signalling. This
means that B2BUAs often implement an RTP/RTCP stack as well, whether
to act as media transcoders or to just passthrough the media
themselves, thus leading to separate multimedia sessions that the
B2BUA correlates and bridges together. If not disciplined, though,
this behaviour can severely impact the communication experience,
especially when statistics and feedback information contained in RTCP
packets get lost because of mismatches in the reported data.
This document defines the proper behaviour B2BUAs should follow when
also acting on the signalling/media plane in order to preserve the
end-to-end functionality of RTCP.
