Hi Alex,
The problem I am having is that I am receiving one way audio or none at all for some
calls.
For example I have two pones behind the same NAT and they can call each other without any
problems, they can also call out through an asterisk gateway. The problems occur when
there are incoming calls from the gateway.
I have looked at the SDP and they have local addresses, so I use the
fix_nated_sdp("15") option and calls from the gateways work, however now calls
between the two phones inside of the same NAT fail. I think this is because the devices
can talk to each other directly, however when the SDP is changed to the NAT'ed address
they can not.
If there is a way to check if they are behind the same NAT device, I could then only
fix_nated_sdp("15") only when needed.
Thanks,
Ross
