Thanks Greger, I’ve already worked through the getting started doc and think I’ve got a good understanding but am still getting the one-way audio. Can you suggest anything to help me understand how I can track the problem? Thanks gareth.

Can someone help?

 

I am fairly new to SER and Mediaproxy and can’t find a detailed explanation of how nathelper etc work, so I’m struggling!

 

My config is:-

 

SER  0.9.6

Mediaproxy 1.7.2

Fedora Core 4 86x64

 

SER and Mediaproxy run on the same server which acts as a gateway to a remote Sonus PSTN gateway over a VPN.

 

I also use Asterisk on my local network. The SER server acts as a router between Asterisk servers and the PSTN via the Sonus. This works fine but my problem is when I attempt to use X-Lite 3.0 UA behind NAT on a remote network. Asterisk is not used in this config but proves that two way audio is fine using SER and the Sonus gateway.

 

Problem: X-Lite behind NAT on remote network to Sonus PSTN gateway via SER and Mediaproxy, I get only one ay audio. The audio is fine from X-Lite to PSTN but not in the reverse direction.

 

Thanks for your help
