    Allow for media to arrive from an alternate source when responding to a reinvite with 491.
    
    When we receive a SIP reinvite, it is possible that we may not be able to process the
    reinvite immediately since we have also sent a reinvite out ourselves. The problem is
    that whoever sent us the reinvite may have also sent a reinvite out to another party,
    and that reinvite may have succeeded.
    
    As a result, even though we are not going to accept the reinvite we just received, it
    is important for us to not have problems if we suddenly start receiving RTP from a new
    source. The fix for this is to grab the media source information from the SDP of the
    reinvite that we receive. This information is passed to the RTP layer so that it will
    know about the alternate source for media.
