[SR-Users] SER nathelper+RTPproxy

[Medina Curafina]

I am writing to you, 'cause I have some issues about SER work. I installed
ser-0.9.4, and test it in my local network, and everything works fine with
hello_world.cfg.
After that I had different situation. I wanted to make a call from one of my
local hosts to remote host (which I registered to SERWeb in format
"username"@iptel.org). Of course I changed my ser.cfg file from
hello_world.cfg into example.cfg (which one I send you in Attachment, grey
parts are changed lines, because I need to show work of nathelper module of
SER).

I Installed RTP Proxy from CVS, and followed basic instructions.
so, in my local network I am host host at 192.168.x.x <102 at 192.168.x.x.>
(x-Lite4) my domain is default one* (localhost)*, my NAT box is Cisco
Lynksis Router. When I make a call (host 102-->SER-->NAT
translation-->SERWeb(213.192.59.75)--->external IP of my friends PC), I can
reach him (He can hear a ringing tone, but when he answers can't hear me,
and I still get ringing tone, and after 7 second it looks like he canceled a
call). In Wireshark I captured INVITE, 100, 180,200, and 487 "Request
Terminated" messages. In section of VOIP Calls Graph, I see that messages
didn't pass further off SERWeb.

I am just beginner in SER use, and I really need your help. I really tried
to understand what to do, I get through documentation about RTP Proxy and I
feel that I make some mistakes in that part. Is there anyone who can give me
advice what I should do, and where am I wrong?

Hope hearing from you soon,

Very Grateful,

Medy H.
