programmed Saved Number Dial button,
on the display.
In Release 2.0, when a user presses Inspct and then a programmed
Saved Number Dial button, the saved number appears on the display.
When an MLX telephone user's microphone is disabled, pressing a
Saved Number Dial button before lifting the handset turns on the
speakerphone so the user can hear the number being dialed. However,
once the call is answered, the user must lift the handset to talk.
Telephone numbers dialed using Personal Speed Dial are stored by
Saved Number Dial. If the number includes special characters, such as
Pause or Stop, the special characters do not work when the number is
redialed using Saved Number Dial. Telephone numbers dialed using
System Speed Dial are not stored by Saved Number Dial.
All outside numbers dialed using Saved Number Dial are recorded on
the SMDR report.
When Saved Number Dial is used on a call made with a Shared SA
button, the number is stored on the telephone where Saved Number
Dial was used, not on the principal extension.
The Saved Number Dial feature can be used to dial an outside number
of the telephone to which a call is being transferred.
