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-TDL 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.
