Internet telephone companies are huge these days. Clark has had Vonage in his home for about three years, for example, and he gives it an “A” so far. Mainstream players are now starting to adopt the idea, as well. Comcast, the nation’s largest cable company, is going to offer Internet phone service for $40 a month with unlimited local and long distance calling. That is 50 percent higher than typical phone services, but Comcast will monitor your burglar alarm and will allow 911 calling, something others have trouble with. Clark doesn’t think that price will last for long, either. It will move down after a while, so keep an eye on this one.
