I just bought my MJ over the holidays (purchased Dec. 21 at Radio Shack) and installed it on Jan. 4. I've been singing its praises until yesterday, when it quit working.
I have a handset attached to the MJ, and when I call the MJ (from my cell phone for example), the phone rings and I can pick up the handset and connect, but cannot hear the caller.
However, when I call the MJ and I have the software answer, I can hear the caller fine through the computer speakers (I don't have a mic to test 2-way comms).
As I said, this was working fine until Sunday...unsure what happened! Any advice is appreciated...I am really hoping not to have to ditch this product. (FYI, I am running Vista, and have read about the many problems associated with the upgrade -- not sure exactly when my MJ did the upgrade -- immediately upon installation, or when).
Oh, forgot to mention, I have tested 2 additional handsets, and 2 additional RJ11 phone lines, with no luck. I also have an AC powered USB hub that "says" it supplies 500a power to each port--but I know the USB hub is at least 2-3 years old.
Thanks in advance to any help you can provide!
Bill
