I recently changed my residential phone from a land line to Verizon digital phone. Now I am totally FIOS. All is okay, except for caller ID. Only "Incoming Call" is displayed on my home phone. I worked with Verizon support by telephone (my account has caller ID activated) for an hour and, based upon advice from support, brought the wireless box to the local Verizon store for a technical inspection. All is okay. Caller ID worked when I had a landline. The local Verizon store advised me to bring the box back again if it still didn't work, which I will do. Any ideas before I bring the box back? My telephone is a Motorola Model L404C. Thanks.
