Special characters may be needed when programming outside Auto Dial
buttons. Each of these characters counts as one of the 28 digits allowed.
A listing cannot be used if the first character of the listing is a punctuation
character such as a hyphen.
An MLX20L telephone user (excluding a QCC system operator) can
display up to 16 Personal Directory listings on the Home screen.
Frequently used features and not Personal Directory listings are displayed
on a QCC system operator's Home screen.
A user can add, change, replace, and delete listings from the Personal
Directory.
While the Directory feature is in use, the LEDs on the telephone go off and
the telephone rings just as it does during programming. The user can answer
calls but cannot determine whether a call is ringing since ringing and LED
indication are not operating normally.
If a user tries to dial a System Directory listing with incomplete information
(for example, the name field is populated but the number field is not), the
user continues to hear dial tone and the number is not dialed.
When a listing is not located and the message "No Match Found" is
displayed, selecting Next or Previous does not reverse the search direction.
To reverse directions, the user must press the Home or Menu button to exit
and repeat the search process from the beginning.
The search screens do not show the type of directory (System, Personal, or
Extension) being used.
An MLX-20L telephone user can program account codes either individually or
with a telephone number in a Personal Directory listing. However, the user must
lift the handset or press the Speakerphone button before selecting the listing
from the display.
When a marked System Directory listing includes a toll telephone number in
addition to an access code, using the System Directory to dial the number
overrides any calling restrictions (such as toll or outward restrictions) assigned
to the telephone.
A user with an outward-restricted telephone cannot dial an outside number by
using a Personal Directory or System Directory listing (excluding a marked
System Directory listing) unless the number is on an Allowed List assigned to
the telephone. A user with a toll-restricted telephone cannot dial a toll number
by using a Personal Directory or System Directory listing (excluding a marked
System Speed dial code) unless the number is on an Allowed List assigned to
the telephone.
