I just got digital voice installed about 6 weeks ago and so far love it. Call clarity as good or better than we had with Qwest. Actually its better, because whenever we would get heavy rains, the water would get in the connection post for the old underground phone cable and cause hum or sometimes even short out and knock out the service. No problems with that now. We got a SMC D3GNV modem that was just released recently and combines phone and internet service in one unit. The SMC has a 4 port wired router and wifi built in. What sold me was the promo rate for the first year. I hope they will extend some sort of discount again at the end of the year, the regular price is pretty steep. Other we might rethink going back to Qwest. They are Century Link now, maybe they will make improvements in the next year.
If Meshuggah is a call center employee, he should know that the customers existing phones and inside wiring still operate in analog mode with digital voice service. The phone modem converts digital cable signals into conventional analog phone signals, including the 90v ring signal. If the existing inside wiring worked fine before, it will be the same with digital voice.
