WSJ.com - Comcast Plans Major Rollout Of Phone Service Over Cable: "Comcast Corp., the nation's largest cable-TV operator, is set to announce today an ambitious push into the phone business, a major escalation in the telecom wars that promises to pose one of the biggest challenges ever to the U.S.'s phone giants.
After two years of keeping Wall Street and the telecom industry guessing about his phone strategy, Comcast Chief Executive Brian Roberts will detail his plans at an investor conference in Phoenix.
'There is going to be a profound change in what a phone is in a home and we're going to be part of that process,' Mr. Roberts said in an interview.
Comcast plans to market an Internet-based phone service to 15 million homes by the end of 2005 and to practically all 40 million of the households that have access to its systems within 18 months. The company hopes to have eight million phone subscribers within five years, or 20% of the homes its cable lines pass by."

I've been using Comcast phone service for year -- no complaints.
