I am seeing 2 problems with nathelper and rtpproxy. One I have seen mentioned on the list but no solution or explainations that I can find. 1. I am seeing the following in my messages file Oct 29 11:01:34 serv1 ser[9229]: ERROR: extract_mediaip: no `c=' in SDP Oct 29 11:01:35 serv1 ser[9229]: ERROR: extract_mediaip: no `c=' in SDP Oct 29 11:01:36 serv1 ser[9227]: ERROR: extract_mediaip: no `c=' in SDP 2. In some situations the BYE messages don't hangup the call I am using yesterday unstable CVS tree.
