Hello all. I used to be a regular here but stopped visiting a few years ago when work and everything else left little time for my hobby. But now I'm back and this is my first post.

Anyway, to the point...

I have VoIP service set up on my computer. I don't use an EMTA modem or router with built-in phone adapter. Rather, I just use a soft phone. The program I use is X-Lite by CounterPath. Anyway, until recently, I did not have a router, and my modem was directly connected to my computer via patch cable. At that time, my VoIP worked normally. After I installed the router, my VoIP connection began to act strangely. Incoming calls work fine, but when I try to call someone, the connection terminates after exactly 20 seconds. It happens every time and I'm not sure why. Even stranger, like I said before, the outgoing calls will connect and I will be able to talk for 20 seconds, but after 20 seconds, it dies. And its at EXACTLY 20 seconds. I reconnected my modem directly to the computer just to verify that it was indeed because of the router.. and my suspicions were confirmed. It worked fine without the router. So, why would my router cause these problems? It does have a built-in firewall but I don't understand why it would work for 20 seconds and then not work. I am proficient with computers but I will admit I know next to nothing about networking aside from installing the hardware and connecting to networks. Do I need to use port triggering or port forwarding? I'm lost...

Thanks for your time!
