Saved Number Dial allows a user to selectively save the last number dialed from
a multiline telephone and call the number again without manually redialing. The
user can save the number even if the person being called answers. The number
saved is any extension or telephone number dialed by using one of the following
methods:
The complete number is manually dialed on the dialpad.
The number is dialed by using a Personal Speed Dial code.
The number is dialed by using a programmed outside Auto Dial button.
Unlike Last Number Dial, the number saved by using Saved Number Dial is not
replaced each time the user dials a new number by using any of the methods
above unless the user presses the programmed Saved Number Dial button
before hanging up.
Queued call console (QCC) system operators cannot use Saved Number Dial.
Saved Number Dial requires a programmed button. To save a number by using
Saved Number Dial, a multiline telephone user presses the programmed Saved
Number Dial button before hanging up. The green LED next to the programmed
Saved Number Dial button does not go on when the feature is used.
To redial a number by using Saved Number Dial, the multiline telephone user
selects the appropriate line for the call and presses the programmed Saved
Number Dial button. The number saved by the feature is dialed automatically.
MLX display telephones users cannot use the feature by selecting it from the
display, but can use the display to program the feature onto a button.
Saved Number Dial requires a programmed button and cannot be used on
single-line telephones.
