Caller ID
Considerations and Constraints
General
An organization must subscribe to the Caller ID service in order for incoming calls
through the 800 GS/LS-ID port module to receive Caller ID information (loop-start
lines only).
Caller ID/PRI ANI Comparison
Caller ID information arrives between the first and second ring at an extension.
PRI ANI uses the second screen of the telephone display to show the called party
number, while Caller ID generally uses this page to display the facility number.

data arrives. Calling Party Number information appears in the PRI ANI
format. However, outgoing calling information is not displayed.
Caller ID information is not displayed when a user turns on Do Not
Disturb.
If a user turns on Do Not Disturb while receiving Caller ID information, the
information remains on the display.
The systemwide LS-ID delay, if programmed, is in addition to the
Forwarding Delay. The total delay is the LS-ID delay plus the Forwarding
Delay.
Caller ID information appears on the display. Outgoing call information is
not displayed.
When using Headset Auto Answer, program the LS-ID Delay option to
avoid loss of Caller ID information.
Caller ID information appears on the display whether or not Night Service
has been activated.
Caller ID information appears on the display of shared personal lines.
Outgoing call information is not displayed.
Collisions are avoided on 2-way trunks. Trunks programmed with the
LS-ID Delay option are not seized from a pool for outgoing calls if a call is
coming in on that trunk.
Caller ID information is not retrieved on remote access lines/trunks unless
LS-ID Delay is programmed for the line/trunk because the calls are
answered too quickly.
