Thanks! Are there any SDP interoperability concerns with using it?

The other aspect of this that I am puzzling over is where the packets in
this loop are coming from. The call is long dead, the ports involved are
not in use (per the RTPEngine call list), but I'm still getting:

Aug 08 12:50:00 gw1 rtpengine[18934]: ERR: [992251125_16092378 at x.x.x.x port 60368]: Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible

Are these RTP frames that were previously sent at some point during the
call looping?
