RTP and RTCP are processed in the channel thread, the same thread that
is executing dialplan or in a bridge. If that thread is blocked for some
reason or deadlocked then RTP and RTCP would be blocked. At least one of
the ports was not RTCP though. The file descriptors are placed on the
channel and the channel thread polls on them, when data is available the
channel driver is called to read it.

A backtrace would show if anything is locked up.
