MERLIN LEGEND Communications System Release 7.0
Feature Reference 555-670-110
Features
Caller ID
Calls returned after the transfer return interval expires also display standard
incoming call identification information.
Considerations and Constraints
General
An organization must subscribe to the Caller ID service in order for incoming calls
through the 800 GS/LS-ID, 408 GS/LS-ID-MLX, or 412 LS-ID-ETR 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.
Mode Differences
Behind Switch Mode
If a customer subscribes to both Caller ID and a central office's call-waiting
service on the same line, Caller ID information for the first incoming call is
transmitted and appears at the display. The communications system, however,
does not provide the Caller ID information for the second (call-waiting) call.
Feature Interactions
Call Waiting If you have both the system feature Call Waiting and the central-
office service Caller ID on the same line, the Call Waiting
information appears on the display, but not the Caller ID information
for this second incoming call.
