Resolving Caller ID Feature not Working

From Asterisk Australia

Q. What can I do if the Caller ID feature of the PAP2 is not working?

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 please follow the steps below to resolve this. </p>
