We use Vonage for the business line, and Comcast for the personal line. Both are money savers and we are relatively happy with both. In particular, the buttons and whistles that come with Vonage are wonderful. I have to say that VOIP communication is not 100% as clear and crisp as old fashioned Ma Bell landline communication. But it comes pretty darn acceptably close. A couple of important disclaimers: First, because of the limitation of losing phone service whenever the internet goes down (which happens more often than I'd like), I recommend that anyone uising VOIP also have dependable non-internet dependent communication backup, such as a landline or cell. Secondly, before any of you go out and dump Ma Bell for VOIP, stop, think and check if there will be any complications with things like your home security communication devices and others, some of which won't work with VOIP. Finally, this is to all you businesseds out there with dial-up credit card machines hooked up to your phone jacks.: Be aware that VOIP is NOT compatible with many of them, so be careful lest you find as soon as you dump Ma Bell your credit card machine won't work anymore. In this case, you might need to replace your older dialup machine with a newer 'dual comm' machine that allows hookup to a DSL router instead of a telehone jack. You'll spend a few bucks on the machine, but your phone bill savings should soon make up the difference..
