This is true for INVITE message but as I understand (but I'm not 
familiar with SIP), in the OK message, we can determine which codec is 
used. No?

Well, the mediaproxy module needs an external proxy server. So it seems 
to be too heavy for my needs.
The real time session statistics (from MediaProxy Server) will be very 
useful but I'm not sure it's a good idea to use the server it if I don't 
need the NAT traversal features.
