It depends on the size of your business presently and how fast you plan to scale it. I did not like them at all. Horrible customer service. Reliability and offered features were decent. After them I turned to guides and found getvoip.com, an analyst called me to ask me some specific questions and make recommendations. Just do a search on PBX guide or VoIP guide in Google and sign up for one.
ITP Reviews - VoIP Service Ratings
For the price, ITP phone service is great. I pay $10 each month and use the service on occasion, but when I do, everything works.
I signed up for ITP after reading their reviews online and I decided it doesn't make sense to pay Comcast $35 each month for a phone I don't use.
Since my cell phone is my primary phone these days and I don't want to lose my home phone number that I've had for over 20 years, I picked ITP.
I had to get their help when it came to the installation of the VoIP router box but other than that everything is working well.
ITP is fantastic. It works great. There have been times when there were short outages, but they are normally taken care of pretty quick. Your technical support is the best, they all seem to be experts. A couple of times I did experience a long waiting time for a rep to answer, but typically they answer pretty quick.
Very quick and easy setup of equipment. Got all setup within minutes. Paying less than $15 per month, great deal!
