These phones are digital proprietary telephones which means that they only work on panasonic telephone systems and not on normal analog lines. If you have a panasonic system the correct way is to plug the line into the " To Main Unit ", the handset into " Handset/Headset" and a normal analog phone into " To Tel ". If the wiring on the line jack was not done digitally the phone will also not work
