IP Phone Technology

I figured this would be something that people would interested in.
With the price of gas I figure saving money is on everyone's mind now days.
Vonage is a phone that is through your broadband internet connection.
We have Cable internet in our home and we decided that it would be best to eliminate the high expensive phone bill by doing this.
Pros:
I forget that I am even talking on an IP phone. It doesn't sound any different.
I have the same features I would with a regular phone and more.
I even have a 1-800 number people can use to call me for free.
How Much? $40.00 per month

Cons:
Cable is Out Phone goes out!
But (There is always a "but")
All missed phone calls roll over to the cell phone or voice mail.

You make the choice!! Here is the link again. Vonage
