IP Office Caller Display
Caller display uses the CLIP (Caller Line Identification Presentation) or ANI (Automatic Number Identifier) passed by the Telephone Company via the trunk line. For caller display on analog phones CLIP/ANI is converted to the analog version of the call display service. CLIP/ANI is also used by PC programs such as IP Office Phone Manager and the PC TAPI interface. Thus IP Office users can see the telephone number of the person calling. Extensions can be configured to enable or disable Caller Display. With caller display, the directory feature is used to assign names to recognized numbers.
