Caller ID
Description
Caller ID allows a display system phone to show an incoming caller’s telephone number (called the
Directory Number or DN) and optional name. The Caller ID information is available as a post-
answer or pre-answer display. Normally, the system provides the Caller ID pre-answer display.
With the post-answer display, the user sees the incoming caller’s number/name after they answer
the call. With the pre-answer display, the user previews the caller’s number before picking up the
ringing line. The pre-answer display is only available if the system has Automatic Handsfree for
incoming line/loop keys disabled. Refer to the table on the following for the available Caller ID
displays.
Second Call Display
While busy on a call, the telephone display can show the identity of an incoming trunk or Intercom
call. For incoming trunk calls, the display will show the Caller ID or the trunk’s name if Caller ID
is not installed. For incoming Intercom calls, the display will show the calling extension’s name.
You can set up the system to present the second call data automatically or allow the user to select
the operation of second calls (with service code 779).
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. There are two types of Caller ID mes-
sage formats currently available: Single Message Format and Multiple Message Format. With Sin-
gle Message Format, the telco sends only the caller’s phone number (DN). The DN is either 7 or 10
digits long. In Multiple Message Format, the telco sends the DN and the caller’s name. The DN for
this format is also 7 or 10 digits long, and the name provided consists of up to 15 ASCII characters.
Telephone’s display can show up to 12 Caller ID digits.
Once installed and programmed, Caller ID is enabled for all types of trunk calls, including:
• Ring Group calls
• Calls transferred from another extension
• Calls transferred from the VRS
• Calls transferred from Voice Mail (unscreened)
• Direct Inward Lines (DILs)
Caller ID temporarily stores 16 calls (total of abandoned and unanswered). New calls replace old
calls when the buffer fills.
