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 enabled. 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 message formats currently available: Single
Message Format and Multiple Message Format. With Single 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
•
Direct Inward Lines (DILs)
Caller ID temporarily stores 16 calls (total of abandoned and unanswered). New calls
replace old calls when the buffer fills.
Outputting Caller ID Data
The system includes the Caller ID data on the SMDR report. The report provides the
incoming call’s DN in the DIALLED NUMBER field. The CLASS field shows PIN (just
like all other incoming calls).
