We can now get telephone service over our Comcast fiber optic cable internet/tv service. Price seems OK.... $39.95/mo UNLIMITED calling in U.S. & a few other places that I never call anyway. No long dx service needed. FAQs says voice service is very clear & undistorted.

But, does anyone have first-hand experience?
