I ordered Vonage. $18.54 including tax for 400 minutes a month. I had to take the plunge, AT&T is so very secretive as to their rates. You can't even get them on the phone during weekends--what is this, 1984?
Thats 13 minutes a day you would have to talk to use up the 400 minutes. We only used that up one time and that was because one person called me quite a few times that month and I talked for over an hour each time.
Did you have them send the unit to you or go buy it yourself?
I think you will be happy with it. It has been a year that I even thought about it. It is tucked away behind my wife's computer so I never even see it.
