Well, since this thread was revived...
Does anyone else have a problem with incoming DTMF? I can call out on the MJ, hit an AA and dial fine. But if I call into it I can not dial TT. I listened to the line and hear static/screech instead of a clear tone.
Is my unit bad, or does everyone have this problem? Their support was no help. They had no information about it and could not even tell me if I was the only one with the problem.
Other then that, it works great.
