I signed up for the phone right when it first came out in my area (~ 2 yrs ago). It was crystal clear- all the time, no problems. Lately, I can tell that the system is more congested- I get some voice drops or distortion (like a cell phone). Makes me wonder if Charter can handle any more customers. The good thing about phone, is it is regulated, and they can't afford to have downtime. But bad call quality is not downtime, unfortunately.
