A few months ago I received a replacement hopper and ever since, I have to hit the red reset to get Caller ID working. This is a real pain as we rely on it to screen calls and it is not until it is not working do we realized that we have a problem. I look at Caller ID settings and it is always ON. I even tried turning it off, Hitting Save,m exiting and going back into the settings and turning it on, and hitting save. Also a check of the phone line always shows it is ok even if Caller ID is not working.
