Have 2 different caller id boxes. They both were working. I was having line noise problems so the phone company came out and fixed my line and now caller id only works on one of the boxes? I can switch the boxes to different lines and the same machine always fails. What could it be. Weird that this definitely started to behave this way after my phone line was worked on?
Any ideas?
One possible idea, on the troublesome caller ID reverse the 2 lines going to tha that box (I use a Radio Shack wall mount phone jack to handle this). I haven't had this trouble with my CID unit but I recall other devices not having reverse polarity on the house wiring.
