Hello List. Thanks for the answers about my last question. Now i have another problem. I installed mediaproxy to work with some NAT'd clients. When a NAT'd client calls to another client i only have voice in one way. This, at first sight, seems to be a configuration problem, but i'm using the same configuration that in my lab test and worked ok. So i'm a little bit confused about this situation. For the other hand the only thing added in this new configuration is a "exec" command that changes the R-URI for all the calls (add a prefix). I'm attaching part of the debug of the call and part of the debug of the mediaproxy (tail -f /var/log/messages).

As you can see the mediaproxy session is ended by timeout. I don't understand why. Can someone give me a hand here?
Thanks in advance
