Don't cry!

+          The minimum interval between two regular RTCP packets for this
+          content, in milliseconds. If no special value is desired (for

+          signalling) one should put MAXUINT (0xFFFFFFFF). In RTP/AVP, the
+          setting this property to 0 means "Do not let RTCP packets exceed 5%
+          of the available bandwidth" and MAXUINT means "use the recommended
+          interval time of 5 seconds as specified by RFC 3550 section 6.2".
+          In RTP/AVPF, both 0 and MAXUINT are used to avoid specifying an
+          additional limit on the rate of RCTP packets (other than that
+          specified by bandwidth constraints for the session). Other profiles
+          may assign different meanings to the value 0 or MAXUINT.

"The special value MAXUINT means according to profile, in RTP/AVP, it means 5
seconds, in RTP/AVPF it means 0 seconds. In both cases, the interval between
RTCP should be large enough to respect the RTCP bandwidth."

That said, maybe we want to get rid of MAXUINT and just force CM to know about
profiles ?
