Features
System Access/Intercom Buttons
assignment of SA or ICOM buttons can be changed through centralized
telephone programming.
A single-line telephone cannot be the principal extension for a Shared SA button,
nor can it have SSA buttons unless the telephone is connected to a Multi-Function
Module (MFM).
Data/Video Workstations
Shared SA buttons should not be assigned to video workstations.

When Auto Answer All is activated, incoming calls on SA Ring, ICOM
Ring, SA Voice, or ICOM Voice buttons can be answered automatically
by the device connected to a General Purpose Adapter (GPA).
If SSA buttons are assigned, they should be programmed for either Delay
Ring or No Ring, and the corresponding SA button at the principal
extension should be programmed for Immediate Ring. This prevents calls
to the principal extension from being answered simultaneously at the
principal extension and at another device with a corresponding Shared
SA button.
Voice-announced calls received at an analog multiline telephone are not
answered by a device connected through a GPA because ringing current
is not sent to the device.
When the Auto Answer Intercom feature is activated, a Hands-Free Unit
(HFU) cannot be used to answer calls on a Shared SA button.
SA buttons (including Shared SA buttons) or ICOM buttons can be
programmed as part of an Automatic Line Selection (ALS) sequence. You
should not interleave different button types (personal line, Pool, SA, or
ICOM). For example, in Hybrid/PBX or Key mode, the sequence might
include all SA or ICOM buttons first, then Pool, then personal line
buttons.
When a call is made on a Shared SA button, the ARS Facility Restriction
Level (FRL) that applies is the level programmed for the telephone with
the button, not the level for the principal extension.
Callback can be used on an SA or ICOM button. When Callback is used
on an SSA button, the callback call from the system rings and the LED
next to the button flashes only at the telephone that originated Callback.
If a user other than the person originating Callback selects a Shared SA
button with a queued callback request and lifts the handset, the user
hears the queuing tone and the green LED on the originator's telephone
goes from flashing to on. If the user hangs up, the green LED on the
originator's telephone goes back to flashing and the system directs the
callback call to the originator. If the user does not hang up, the system
directs the callback call to the user and not to the callback originator.
