Summary:                    in certain scenarios, asterisk can send rtp in an 
unsupported payload type to an endpoint
Description: 
SIP caller A supports alaw/ulaw

Asterisk is configured to support alaw,ulaw,g729 and places all 3 in the
offer to B

SIP called B supports g729,alaw,ulaw putting all 3 in the 200 OK

If B sends audio in G.729 it gets forwarded to A without transcoding.

The first section of the code passes the first incompatible rtp packet to
the core.  There it's detected/treated as a codec change.  This changes the
raw formats.
