It started fine. But as time goes on, the quality become worse and worse. Now 1-2 months later, I can't make calls because the voice quality is soooo bad. Unbelievable. Their tech support told me that it was either the cable to the modem was bad, or I was losing packets thru the cable modem or Comcast. Called Comcast, they told me that their signal was good. So whatever it was, the whole thing was just not working. Another thing, they started charging before I got my phone # ported over, and the porting took a month.

BAD Experience with ITP. I tried ITP because their website says their adapter will power all the phone jacks in your home. This did not work for me per their directions. When I called to cancel they said I still had to pay the shipping ($16.95) and the Activation Fee ($29.95) and pay to ship the adapter back ($12.00). So, if you want to try VOIP, be aware that ITP will charge you $60.00 even if you return it after 5 days. Next time, I'm using VONAGE - free setup, free activation, and it costs less overall for the first year than ITP.

This is a great company. Easy to install, easy to use. Very good features not available with land line phones. Best of all, the customer service reps are based in the USA, and they are extremely easy to deal with. I have been recommending this to everyone I know.

There servise is first class

I am entering my 5th year with ITP. Qwest made porting my phone number a problem but ITP has worked very well. We rarely use more than 500 minutes/month. If we did i would sign up for the unlimited plan.
