Summary: SDP/RTCP parse error in mediaproxy module

Initial Comment:
After upgrading to latest OpenSIPS 1.6.x branch (revision 6844) and Mediaproxy 2.4.2, I discovered errors such as

ERROR:mediaproxy:get_rtcp_ip_attribute: invalid `a=rtcp' line in SDP body

in my syslog. However, SDP seems to be correct:

c=IN IP4 192.0.2.10
m=audio 7078 RTP/AVP 9 8 0 2 102 100 99 97 18 120 121 101
a=sendrecv
...
a=rtcp:7079

As of RFC 3605 example RTCP encodings could be:

    m=audio 49170 RTP/AVP 0
    a=rtcp:53020

    m=audio 49170 RTP/AVP 0
    a=rtcp:53020 IN IP4 126.16.64.4

    m=audio 49170 RTP/AVP 0
    a=rtcp:53020 IN IP6 2001:2345:6789:ABCD:EF01:2345:6789:ABCD

I gave a quick look at the source code, it seems that the Mediaproxy module expects the variant in the middle (port and IP) and logs the above error in the "port-only" variant.

Best regards,
Thomas Gelf
