Caller ID
Description
Caller ID allows a display terminal to show an incoming caller’s telephone number (called the Directory
Number or DN) and optional name. The Caller ID information is available as pre-answer display. With
the pre-answer display, the user previews the caller’s number before picking up the ringing line.
 On the CPUII for Caller ID (also used for DTMF receivers and Call Progress Tone Detection) 32 resources
are available. The DSPII-U10 Unit provides an additional 32 resources.
Second Call Display
While busy on a call, the telephone display can show the ID of an incoming trunk or Intercom call. For
incoming trunk calls, the display shows the Caller ID or ANI data or the trunk name if Caller ID or ANI are
not installed. (Refer to
T1 Trunking (with ANI/DNIS Compatibility) on page 2-941 for more information
on ANI compatibility.) For incoming Intercom calls, the display shows the calling extension name.
Caller ID supports the Telco 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. Two Caller ID message formats are currently available:
Single Message Format and Multiple Message Format. With Single Message Format, the Telco sends
only the caller’s telephone number (DN). The DN has either seven or 10 digits. In Multiple Message
Format, the Telco sends the DN and the caller’s name. The DN for this format has seven or 10 digits,
and the name provided consists of up to 15 ASCII characters.
The telephone display can show up to 12 Caller ID digits (for non-ACD calls).
Once installed and programmed, Caller ID is enabled for all trunk calls, including:

Ring Group calls

Calls transferred from another extension

Calls transferred from the VRS
