[Serusers] Audio Problem

Hi all, I started using SER a few weeks back. It's working pretty good, but i am having some issues with audio. This is the scenario: softphone <-> NAT <-> SER/Public IP <-> NAT <-> softphone I have a softphone in our local network trying to call another softphone in another network. This works perfectly, I am having no issues. But when I try to call a softphone in the same local network, the connection establishes, softphone says audio active, but there is no sound. I think this is because of NAT, but how can i make it work for phones connected in the same network? Can anyone help me in figuring out the problem, or any pointers or links from where i can find some useful information? Any help on this regard would be greately appreciated.
