How do i stop the phone going through to the fax

Go to an electronics store (Radio Shack) and buy a spliter. They sell a spliter that recognizes the call as a fax or phone call and sends signal to proper line. When you hook up the unit you will have your line in, then the outputs will be marked one to the fax and one to your phone. Once you install this your problem will be solved. You only have to hook one at at the fax machine not at all phone jacks.
