I don't think it's going to work for you Jack. I have found several apps that it won't work on, I couldn't get it to hear the digits dialed by my voicemail system to notify me of a message, I could monitor the line and hear the tons, but could not break dial tone on the magic jack. That said it works well about 90% of the time for general long distance voice calls, when it doesn't I hang up and dial again and it usually works fine. I have found that it eats up a lot of memory so I use it on an old laptop in the basement and feed the line into my phone system so it doesn't slow down my desktop.
Hal is right though, you are lucky when you get what you pay for, and with the low price of this thing, I'd say you get more. It just doesn't do something you and I would like it to do.
