First, test the DuraFon 1X on a different phone line (eg. at a friend or neighbor's house) to verify it is working.
If it works ok at another house then there is a problem with your line and Verizon will need to repair it.
If the DuraFon 1X does not work on a different phone line then it likely has a fault, and will need to be repaired or replaced.
Ok, let me know how it goes.
