Hi Klaus

I'm trying to do the following:

UA behind a NAT ----> SER+MEDIAPROXY --------> B2BUA -----> 
SER+MEDIAPROXY------> PSTN GATEWAY

The first callee is the UA behind the NAT and then the B2BUA calls to 
the PSTN.
The B2BUA has a public IP address (isn't nated)
The PSTN GATEWAY has a public IP address too.
 
I'm attaching the full NGREP sniffing from the call in order you can see 
all the flow.

Regards

Alberto Cruz
