[OpenSIPS-Users] Openser running between 2 networks

[Robert Dyck]

I also use openser as an outgoing proxy. At first I had the proxy listening on 
both interfaces and used rtpproxy in bridge mode. I decided that was not 
necessary. Now on the local phones I use the proxy's public address as the 
outgoing proxy address. I no longer use rtpproxy in bridge mode. Both the 
local phones and external phones can connect with the rtpproxy public 
address.
