Caller ID
n 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 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
·
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.
Caller ID to Abbreviated Dial Name Tagging
If the received Caller ID number matches a number in the Abbreviated Dial bin the name assigned to
the Abbreviated Dial bin will be displayed.
Note that if the received Caller ID includes the callers name then the Abbreviated Dial Name Tagging
will not occur; the callers name will be displayed.
Caller ID to Single Line Telephones
The XN120 can send the caller ID to an analogue single line telephone (SLT) connected to one of the
ST telephone ports. The system will also send the calling party number and name for internal calls to
the SLT.
Note. When caller ID is enabled the ringing pattern is fixed at 2 Sec ON/4 Sec OFF for internal and
external calls.
Conditions
To have pre-answer Caller ID from the voice mail, the call must be an unscreened transfer.
