Its not a matter of whether the "180 comes with media". The i80 may come
with SDP, but it doesn't come with media. :-)
Its a matter of whether the UAC is *receiving* media at its media port,
which could happen even without receiving SDP from the UAS. If media is
being received, and a 180 has been received then the media should be
played in preference to local ringback. If media is being received and a
180 has *not* been received, then the media should also be played.
That is the theory. In practice, many want to receive an answer before
beginning to render media. You will have to make that choice.
