I'm a fairly new VOIPo customer as well as this being my first VOIP experience moving from AT&T pots. Things were going great until the last few days or so, I'm experiencing the exact same issue as reported here; no ringing then the called party will answer after a long silence (15-20 secs or so).

One time I called my Dad at his cabin and it stayed silent for a long time with no answer, when I tried that number from my cell phone his line was busy. I did get through some time later with my cell and found that he was on the internet (dialup).

So I've experienced a no ring with long silence then answer as well as a no busy signal at the called party, I'm really hoping these glitches get fixed ASAP.

My wife is getting a little chippy over these 'glitches' which she has also experienced,of course she has little tolerance for as them as they weren't experienced with AT&T.

I am on Charter cable in Michigan (no internet access issues during these phone issues), D-Link DIR-655 (no changes from initial install when the service was working problem free, Linksys RT31P2 router (I have not had the line lights go out on the device).

I will be starting a ticket but wanted to share with others.
