I switched from Comcast to ITP effective 12/6/11 and ported my phone number over to them.  Within a few days I realized that the voice quality was significantly worse than Comcast (e.g. couldn't different 's' from 'f' when people were speaking) and the tech support couldn't solve the problem.  so I figured it was either my set up or that the service was just inferior. Part of the problem may be that the ITP box connects to an ethernet port on my router, while with Comcast, the phone cable directly connects into Comcast's cable modem.  On 12/9/11 I called Comcast to get the phone number ported back to Comcast.  ITP made it very difficult for Comcast to port the number back.  I spent a few hours on the phone with Comcast, ITP, sometimes with both firms in a conference call to resolve the issues.  Finally, on Feb 27 2012, my number was ported back to Comcast and I am enjoying the higher voice quality again.  Also, I had ITP basic service and the monthly charge is $26.17 (that is what my credit card statement says), and they also charged me ~$45 for the little Linksys box that is required for their service.  So I think they are not advertising the correct rate.
One other piece of information:  I based my decision to select ITP on the website whichvoip.com.  So after this experience with ITP I wanted to provide a review (there are many reviews on this website).  It turns out one cannot provide reviews!! which makes me think that the website whichvoip.com is fraudulent.  I filed a BBB complaint in this regard.
It is a shame that even review sites you cannot trust anymore!  I hope this is useful and thank you for reading this post.
