The Calls-In-Queue-Alarm button for a calling group is assigned on a
multiline telephone by programming an inside Auto Dial button with the
calling group's extension number. When a DSS is not available, the
calling group supervisor uses Auto Dial buttons programmed with each
calling group member's extension to monitor group member availability.
If headset operation is activated on the telephone or console, select a
line button before using Auto Dial to dial an extension or an outside
number.
A number you dial by pressing a programmed outside Auto Dial button
is saved for Last Number Dial as if you dialed it with the dialpad, but
special characters do not work. An extension dialed when you press a
programmed inside Auto Dial button is not saved for Last Number Dial.
When an MLX telephone user's microphone is disabled, pressing an
Auto Dial button turns on the speakerphone so the user can hear the
number being dialed. However, the user must lift the handset to talk
once the call is answered.
You can program an extension for a speakerphone paging group on an
inside Auto Dial button.
An operator can program park zone codes on inside Auto Dial buttons.
An inside Auto Dial button can also be programmed with a user's or
system operator's own extension number and can be used to park calls.
When the system is programmed for One-Touch Hold with manual
completion, you hear a busy signal when parking a call at your own
extension number and must complete the transfer by hanging up or
pressing the Transfer button.
Only an outside Auto Dial button—not an inside one—can be used on a
personal line.
Pool dial-out codes cannot be programmed on inside Auto Dial buttons.
A pool dial-out code can be programmed on an outside Auto Dial
button when a telephone number is also included.
A number you dial by pressing a programmed outside Auto Dial button
can be saved for Saved Number Dial by pressing the programmed
Saved Number Dial button.
You cannot program a Signal button and an Auto Dial button for the
same extension. Attempting to program both types of buttons for one
extension causes the system to erase the button that was programmed
first.
All numbers dialed on an outside call using Auto Dial are recorded on
the SMDR report.
