I am setting up a SER/Mediaproxy/MySQL box. I have it setup and running
except for NAT. When I put up a call this is what my session look like. The
127 are the fakeconversations.py. The other session is my live traffic but
the other end has all ????????????????.  Any ideas. I am using the basic
SER/Mediaproxy config below.

Caller            Via                Called           Status    Duration
Codec         Type   Traffic
