A number dialed by pressing a programmed outside Auto Dial button is saved
for Last Number Dial as if it were dialed with the dialpad, but special characters
do not work. An extension dialed by pressing 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.
An extension for a speakerphone paging group can be programmed on an
inside Auto Dial button.
A system operator can program the park zone codes on inside Auto Dial
buttons. An inside Auto Dial button can also be programmed with a user's
(including 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, a user hears a busy signal when parking a call at his or her own
extension number and must complete the transfer by hanging up or pressing
the Transfer button.
Only an outside Auto Dial button can be used on a personal line-an inside Auto
Dial button cannot 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: however, one or two Pause characters must
be programmed before the telephone number to allow time to receive local
telephone company dial tone. Pause characters are entered by pressing the
Hold button.
An Auto Dial button cannot be programmed on a QCC.

for Saved Number Dial as if it were dialed with the dialpad, but special
characters do not work. An extension dialed by pressing a programmed inside
Auto Dial button is not saved for Saved Number Dial.
A Signaling button and an Auto Dial button cannot be programmed for the same
extension. If a user tries to program an Auto Dial button when a Signaling button
is already programmed, or vice versa, the feature being programmed erases the
previously programmed feature.
All numbers dialed on an outside call by using Auto Dial are recorded on the
SMDR report.
