      Rajesh,
Again, copy the list. The config you sent is NOT the onsip.org config and as I have said: You call force_rtp_proxy several times.

hi
I see that ser is appending to new IP address multiple times in the Invite message instead of rewriting the address. I had copied entire ser.cfg iam using. Please look at it and let me know if anything is wrong.

If you use a vanilla onsip.org config, it's pretty thoroughly tested by now, so I would be tempted to say that there is something wrong with the client or the setup of the client.
