In any case, it's easy to check out. Get a neighbors phone and plug it in to one of your jacks. No hum, phone problem. Still hum, find network interface box. Most newer ones have a customer removable cover and a test jack. Plug good phone in test jack. If you still hear hum, it's in the network so call the phone company. If you don't have a test jack, call the telco. They will tell you where the problem is... Ken@cup.portal com
