This is my first week using my Voipo line exclusively as my home phone and for the most part it has worked well.

I have had several calls either originated on the Voipo line or to the Voipo line that result in a connection but no audio. It is just dead air. I can hangup and try the call again and it goes through fine.

I currently do not have any port forwarding setup in my router. Should that be my first try?

I have a rt31p2 connected behind a Belkin N+ router.
