The call is made from a Nated ata186. I got the
message from rtpproxy:
rtpproxy: can't accept connection on control socket: Invalid argument
rtpproxy: can't accept connection on control socket: Invalid argument
The corresponding Ser output:

Start rtpproxy with `-f' flag which will
prevent it from going into the
daemon mode, make a test call and send me rtpproxy's output.

what does direction=active
means?
And:
Name: force_rtp_proxy
Params: none
So what does mean?
Your reply is so soon, Maxim.

Subject: [Serdev] nathelper updated to support RTP proxy
_______________________________________________

http://lists.iptel.org/mailman/listinfo/serusers Folks,
Today I've updated nathelper module to support RTP proxy. It would
be nice if somebody can test it on platforms other than FreeBSD,
because I don't have an access to such boxes right now. The RTP
proxy itself can be downloaded from:
https://demo.portaone.com/~sobomax/PortaSIP/rtpproxy/
Any feedback is greatly appreciated.
-Maxim
P.S. I've committed it to the HEAD, those with 0.8.11 prerelease
please apply the following patch:
https://demo.portaone.com/~sobomax/nathelper.diff
