Feature Reference
Entering Authorization Code
While you enter the assigned authorization code, you hear internal dial tone. If
you do not enter the code within 15 seconds, the feature is deactivated.
If a telephone with a display is used, the display shows asterisks instead of the
entered digits.
To complete entry of the authorization code, either press a programmed
Authorization Code button again, or dial a # to signify the end of the code. If the
entered authorization code matches an assigned code, you continue to hear
internal dial tone and can start dialing the telephone number.
The green LED associated with a programmed Authorization Code button
becomes steady to indicate that an authorization code has been successfully
entered. The LED remains steady as long as the Authorization Code feature
remains active.
If the authorization code is not valid, you hear an error tone (a high tone
followed by a low tone). The green LED associated with a programmed
Authorization Code button goes off to indicate that the Authorization Code
feature is not active. An MLX display telephone shows the message
, and an analog multiline display telephone shows the message
Deactivation of Authorization Code
Each entry of an authorization code is good for only one phone call. After
completing a call, the current extension loses "home extension" privileges. It
also loses privileges for subsequent calls after putting a call on Hold, or after
initiating Recall, Headset Hang Up, or Park features. If a far-end disconnect is
not received from the central office, you must go on-hook or select another
outside line to deactivate the Authorization Code feature.
After the feature is deactivated, the green light next to the Authorization Code
button (if present) turns off.
