[Serusers] Nathelper & rtpproxy

[Glenn Dalgliesh]

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. Client I am using in the test lab are Budgetone and x-lite softphones

and hear is my ser.cfg

Thanks
