Title: too much interference
Review: I bought this item for a customer. There was so much electrical noise on the system that you couldn't hear a dial tone at all. I then took the system to my house which has a good grounding system thinking that the electrical interference would be minimized but found that although it would work, there was the electrical hum there also and very loud. I tried to use it for a fax line, but half the time the faxes wouldn't go through so I had to disconnect it and I'm probably going to throw it away since I've had it so long I don't feel right about returning it.
