Quote from a parent: "We use it. I think it's great. I would like to recommend it to others."
Quote from a parent: "We tried this early in the year. It broke twice in a month. It was great when it worked but it was very unreliable."
iTalkBB.
"iTalkBB is OK 99% of the time, not 100%. There was a downtime, no service. My friends who used iTalkBB are still using it." "When trying iTalkBB, the quality is super — clear voice and no disconnection. However, just after the one-month free trial, voice is no more clear, still good. There are quite a few disconnections in just one month after the try-out. The worst happened on me with a phone interview. Fortunately, the hiring manager called me back. I wish I had not transfered our home number to iTalkBB. It is not reversable. To summarize, iTalkBB is working, but not working in good condition. So don't rely on it for your important communications, keep another line available."
Skype.
Calling from computer to computer is free.
"Right now I use it only for the free computer-to-computer calls. To my surprise, the voice quality is great. It works better than my international long distance carrier."
