[Serusers] nat - mediaproxy problem only about patton hardware

[Rosario Pingaro]

We are test nat conditions.

We have a ser.cfg configured about mediaproxy and everything works fine in the following configuration:
1. natted sip client (all kind of client) to pstn gateway.     GOOD
2. natted sip client (sipura) to natted sip client (all kind of client). GOOD

I have only the problem form patton (4552) natted to natted sip client. In this case the i have NO audio streaming.

For exemple if call from sipura natted client to patton natted client everything is OK. This is the dispatcher log:

If the same patton is making the call i got the problem about no media streaming. This is the dispatcher log in this seocnd xase:

The main difference is that patton try to send image stream also.

But i am not able to figure out what is the main problem preventing mediaproxy (1.4.2) to work correctly.
