If a call comes in through our AT&T ISDN/PRI to a DID extension the caller id appears correctly on the phone, however, if the call comes through the Unity 4.0 Call Handler, the caller ID appearance is the extension number for the mail voice mail (2000 in our situation). Also, if a call is forwarded from an extension to a cell phone, for example, the caller id is the forwarding extension or the voice mail extension, not the originating caller id.
Any ideas?
