Caller id unit on a separate jack?

Question

ok, I just found out that when I am at work at night my boyfriend is talking on the phone to someone else and then erasing the calls (she is the one calling him) We talked about it and he says he won't do it anymore, but I want to be sure. Is there any kind of caller id unit that I could connect to a separate jack without having a phone connected to it? Thanks!

Answer 1

yes you can hook up a secind caller id unit to anther active phone jack just hide it so he does not know you have it

Answer 2

then why don't you get an caller ID manager!

it will show all the incoming and outgoing calls....also the date and time!!

just put the unit in your bedroom....
