Comcast Expending its Services

The nation's largest cable television company is getting into the phone business.

Comcast plans to offer Internet-based phone service.

It will cost about $40 a month for Comcast high speed Internet customers, but it probably won't be in local markets, like Panama City, for at least a year.

When available, the package will include Caller ID, Voice Mail and Call Waiting.

Verizon, Vonage and AT&T all offer phone-based Internet similar to what Comcast will be offering.
