When the customer is behind NAT, the destination port in SDP is wrong. Freeswitch resolves this by finding the incoming stream and adjusting the destination port to match. (freeswitch disable-rtp-auto-adjust=false) In this case, pcapsipdump does not capture the media bc its looking to match both source & destination ports. My proposed solution would be to match on either or the destination or source port instead of requiring a match on both. This could be a command line option. Thoughts?
