I purchased this machine for our new office because it offered a two-line phone, fax and 8 voice mailboxes. It was the only system I found that had more than three or four mailboxes. The problems we have with the machine are buzzing on the outgoing message, poor sound quality, flimsy fax film that split the first week we used it, and now the additional cordless phone that came with it stopped working. We tried a different (new) phone and that won't work either. The machine clicks when the cordless goes on, but we can't get a dial tone. Sharp said we were past warranty (90 days, I think) so we're out of luck. I sure wouldn't spend money to fix this terrible machine.
