Caller-ID’s are usually telephone numbers. By providing your caller-ID to the party that you are calling, the called party may be able to look you up in an address book, initiate a callback, or just see who is calling.
Sometimes you want to reject calls that come from callers whose Caller ID does not reveal their identity. Most VoIP systems use the name "anonymous" in the caller-ID in such a case. To treat these calls, dial *88. If you have set the call forwarding on busy condition, the PBX will forward anonymous calls to that destination (for example, your assistant). This way, you can make sure that anonymous calls get screened first before you take the call. If you have not set the call forward on busy, the system will play an announcement to the caller that tells him that the call cannot be taken because of the blocked Caller-ID.
To allow anonymous calls again, dial *89.
If you want to place a call without showing your caller-ID, dial *67. You will hear an announcement that the caller-ID will be blocked for all future calls.
