Editorial Comments:

The changes to Section 3.2.4 to resolve my earlier comment have
introduced a clarity problem.  I suggest a minor rewording to fix it.

3.2.4.  Media Stream Mixing

   In a basic session involving only audio there are typically two
   audio/RTP streams between the two UAs involved transporting media in
   each direction.  When recording this media, the two streams may be
   mixed or not mixed at the SRC before being transmitted to the SRS.
   In the case when they are not mixed, two separate streams are sent
   to the SRS.  In the mixed case, a single mixed media stream is sent
   to the SRS.  However, in the case when the media streams are not
   mixed, the SDP offer sent to the SRS must describe two separate
   media streams.
