Dear Klaus,
Between Openser and rtpproxy is no media traffic, just the proprietary
rtpproxy protocol which is used by nathelper module to
control the
rtpproxy.
thank you for the clarification.
1. Use ngrep to inspect the SIP message:
- look if the IP address in the c line in the SDP is
replaced with the
rtpproxy's IP address and the port number is replaced with the port
number allocated by rtpproxy
Using debug=7 I think I saw in the openser log that the c line was not
replaced.
2. use tcpdump/wireshark/.... to verify if there are RTP packets sent to
your server. MAybe there is a firewall which blocks
RTP packets.
I opened all ports so it shouldn't have been a problem.
Very fortunately I started on this trace you suggested. I tried to merge the
nathelper.cfg file (shipped with openser as a factory documentation) with my
openser.cfg. And voilá, it seems to work smoothly! :-D
Thank you for your kind help!
Best regards, Zoltan
