We recently put in a 7200 system in our new office. One of the funtions we want to have is caller ID, so the system includes a CID2 card. All of the trunks are set to type CID with MMC 414.

Every call that comes in is displaying that no CID information is available. I called the technician who programmed our system for us, and he says they may need to swap the CID2 card for a CID1 card.

Does this sound right? Why would Samsung have a CID2 card that doesn't give CID? What else can I check?
