Hey Marek,

This is support added to Asterisk to allow RTCP feedback messages to
influence codec behavior - so statistics contained within those messages
might include packet loss, jitter information, and other network level
details.  The codecs then could presumably act on that behavior (increasing
FEC level, reducing bitrate, etc).  This is separate from any SIP protocol
level messaging.
