Caller ID
Caller ID
Description
Caller ID automatically displays the phone number and optional name for incoming outside calls.
Caller ID allows a display keyset to show an incoming caller’s telephone number (called Directory Number or DN) and optional name as the call is ringing. Caller ID supports the telco’s Called Number Identification (CNI) and Called Number Delivery (CND) service, when available. These services provide the Caller ID information (i.e., messages) between the first and second ring burst of an incoming call.
Caller ID provides the following features:
Single and Multiple Message Format Compatibility
There are two types of Caller ID message formats currently available: Single Data Message Format (SDMF) and Multiple Data Message Format (MDMF). With Single Message Data Format, the telco sends only the caller’s phone number (DN). The DN can be up to 10 digits long. In Multiple Data Message Format, the telco sends the DN and the caller’s name. The DN for this format can be up to 15 digits long, and the name provided can consist of up to 15 ASCII characters.
If no DN is received, no number or error message displays.
