Seems reasonable, so I'll take your advise and start debugging with
tcpdump. My guess is that there is some NAT problem and/or faulty IP
number substitution in SDP (a config error basically.) The strange
thing is that the same config was being used with OpenSER 1.3.X and
these errors did not appear.

I'll start tcpdump and report what I find.
