I am sure someone have already asked this, but why do we need "stereo"
optional parameter and always specify number of channels 2 in RTP map? Can
this be replaced by simply saying that receiver specifies its preference to
receive stereo by specifying 2 channels in RTP map and its preference to
receive mono audio by specifying 1 channel in RTP map? We should still
specify that every receiver MUST be able to receive and decode stereo
signals.
