Features
System Access/Intercom Buttons
When Do Not Disturb is turned on at the principal extension, calls do not ring at
that extension or at other telephones with Shared SA buttons for that extension.
The principal extension or an SSA button can be used to join a conversation in
progress. A maximum of three parties can participate in one call.
NOTES:
ICOM Buttons: Key and Behind Switch Modes
In Key mode and Behind Switch mode, telephones have ICOM buttons, which are
used as follows:
To dial the Idle Line Access code (usually 9) to select the first idle personal
line assigned to the telephone (Key mode only)
To make an inside call
To activate a feature by using a feature code
To receive inside calls, including voice-announced calls, and transferred
outside calls
An ICOM button can have one of three attributes:
Ring. Used to make inside ringing calls, to receive inside and transferred
outside calls, and to dial the Idle Line Access code to select a personal line.
Voice. Used to make inside voice-announced calls, to receive inside
ringing calls, and to dial the Idle Line Access code to select a personal line.
If the person receiving an inside call made from this button has a
speakerphone and it is not already in use or disabled by having Voice
Announce turned off, the call arrives on the speakerphone. Both parties
hear a beep and the called person hears the caller's voice over the
speakerphone. Because voice-announced calls cannot be made to
single-line telephones, a call made on this button to a single-line telephone
is a ringing call even if the single-line telephone has a speakerphone.
SSA buttons cannot be assigned to single-line telephones or other tip/
ring equipment connected to a 016 (T/R), 012 (T/R), or 008 OPT
module. SSA buttons can be assigned to a tip/ring or external alert
device connected either to an MFM in an MLX telephone or to a GPA
connected to an analog multiline telephone.
Shared SA buttons cannot be assigned when the SA button is on a
single-line telephone. A single-line telephone cannot be the principal
extension for an SSA button unless the telephone is connected to an
MFM.
