Delayed Ringing on incoming digital voice.

With Digital Voice, has anyone noticed it takes longer for the phone to ring when calling your home? At times mine has taken anywhere from 5 to 10 seconds before the phone would ring. It acts like the line is down or there is a problem. Awful latency with Digital Voice. At times I believe that switching to digital voice over IP may have been a mistake. This seems to be getting worse.

Any feedback?
