I guess I will have to buy a new phone system. That better work. Landline cuts in and out not solved We havethe ARRIS modem setup where your phone directly plugs into the back. The past 7 month people calling my coxline line cant hear us because the phone cut in and out. Today we received a new ARRIS modem and it is installed correctly and the cordless phone still cut in and out. What should be my next step to check before purchasing a brand new cordless phone system, that may not even solve the problem????
