A call put on hold on an SA or Shared SA button can be picked up at
the principal extension or at any telephone with a Shared SA button for
that extension, unless Privacy is turned on at the telephone that put the
call on hold. The hold reminder tone is heard only at the telephone that
put the call on hold.
Prior to Release 2.1, a call on hold on a Shared SA button can not be
transferred by the user who picked up the call. In Release 2.1 and later,
an inside call on hold at an SA button can be picked up and transferred
by a user with a Shared SA button corresponding to the button with the
held call.
In Release 2.1 and later, a call that has been put on hold at a Cover,
SA, Shared SA, or Pool button can be picked up by a user who has a
personal line button for the call. When the call is picked up, the green
light next to the personal line lights steady; however, the call remains on
hold at the Cover, SA, Shared SA, or Pool button. The user who picked
up on the personal line cannot transfer the call that has been picked up.
To transfer a call on hold at a Cover, SA, Shared SA or Pool, button,
use Pickup instead of picking up on a personal line button.
If Last Number Dial is used on a Shared SA button, the number is stored
on the telephone that used the feature, not on the principal extension.
Line Request cannot be used for an SA or ICOM button.
If a Shared SA button is used to leave a message for a display
telephone user, the extension of the telephone with the Shared SA
button (not that of the principal extension) is shown in the message.
When a principal extension user with an MLX display telephone posts a
message and a call is answered at the Shared SA button, the calling
information is cleared from the principal extension. However, the Home
screen on which the posted message is shown is not restored. If the
principal extension user presses the Home button or makes or receives
a call, the Home screen is restored.
One SA Ring or ICOM Ring button and one SA Originate Only or
ICOM Originate Only button should be assigned to a Multi-Function
Module (MFM). At least one SA or ICOM button must be assigned to an
MFM. Assigning a Shared SA button to an MFM means that the
principal extension can join a call that has already been answered by
an answering machine connected to the MFM.
Night Service calls override any Ring Timing options (Delay Ring or No
Ring) programmed for an SA button and ring immediately. On a Shared
SA button, Night Service calls follow the programmed option
(Immediate Ring, Delay Ring, or No Ring).
Announcements using Speakerphone Paging can be made from a
Shared SA button. However, users cannot join a page (as they can
other calls) on a Shared SA button.
