Summary:                    wrong parsing of received RTCP packets
Description: 
The code for parsing the RTCP packets is buggy. When an RTCP RR/SR frame is
handled, it expects some fields present although they are optional.

E.g. take a look at the RTCP packets in the attached pcap dump. The first
RTCP packet contains a RR without any RTP statistics data. Nevertheless
Asterisk sets the statistics, reading wrong data from the RTCP packet (the
following SDS).

No, sorry. Which branch should I test? pinefrog-1.4 or pinefrog-trunk?
