My incoming calls don't come through. When I answer, I get dead air. They hear some message (not my voicemail). I called my own cell phone and it worked. Then I call the number that was calling me and it didn't work. I had to unplug and replug magic jack to get the thing to work.
The other day:
I chatted with magic jack the other day, because I was having the same issue. They reformatted my drive and did some upgrade. All my numbers were gone.
I don't want to go though a reformat nor having to plung and unplug the magic jack all the time. I looked into changing my "proxy", that blew my mind.
P.S.: My friends call this Cracker Jack!
