Please be informed that CID should work with PAP2. Just make sure that your phone has CID support and that the phone displays Caller ID (CID) information when connected direct to your line to ensure that it will work fine. If the caller ID is not working, complete the steps outlined in this document.
Resolving Caller ID not Working
Click USER1, and go to Supplementary Service Settings. Make sure CID Setting is set to yes, and Block CID Setting is set to no.
Click Regional, go to Miscellaneous, and look for Caller ID Method. Make sure the appropriate Caller ID Method setting is selected (for example, Bellcore for North America).
Click Save settings.
If this does not work, perform a power cycle by unplugging your PAP2 for 30 seconds and plug it back in.
