I would like to know how to configure router port forwarding if I was to have both VOIPo (using a PAP2T) and another provider (using another PAP2T). I currently have UDP ports 5000-65000 forwarded through my router (running Tomato). If I had another provider, they would need some of those ports which would need to be forwarded to a different device.

SIP ports 5060/5061 would remain with VOIPo

I may use something like SIP ports 5089/5090 with another provider (so I could single those out in the port forwarding rules)

But what about the audio ports? They're seemingly random. How do two devices play nicely together?

Thanks...
