Finally! Registered now, you can see me. I too have been having the very same issues with dead air on my handset, ringing on the other end, person picks up and I don't hear a thing. My case is a tad different as I hear nothing during the progress of the call - no dialtone, no ring, no pick-up, no voicemail, no termination of call, nada.

After reading several posts, I powered down for 1 min, then powered back up. My phone seems to be working right now. I also opened a ticket though, as NO calls were working for two days, inbound nor outbound.

Hopefully, they will take a look at it first thing on Monday morning. My friends all think I am a crackpot for doing VOIPo, turn me into a salesman, let's get this fixed! :-)
