Allowed and Denied Lists
What’s this?
Allowed list and Denied list is a group of number strings. Vision uses these lists to support three different
features viz. Toll Control, Dynamic Lock and Call Duration Control.
Toll
Control
Dynamic
Lock
Allowed List
And
Denied List
Call
Duration
Control
Association of Allowed list and Denied list with Toll Control:
When the number is dialed from a station, the Vision compares the dialed number string with the number
strings in allowed list and denied list.
Association of Allowed list and Denied list with Dynamic Lock:
If the user locks the station and thereafter dials a number from his station, the Vision compares the dialed
number string with the number strings in allowed list and denied list for the locked status.
Association of Allowed list and Denied list with Call Duration Control:
If Call Duration Control feature is set on a station, the Vision compares the dialed number string with the
number strings in allowed list and denied list for Call Duration Control (CDC) condition. The Vision disconnects
the call if the number string dialed by the station matches with the denied list for CDC condition.
How it works?
• Maximum 8 allowed lists could be formed.
• Maximum 8 denied lists could be formed.
• Maximum 16 entries (i.e. number strings) can be programmed in one allowed or one denied list.
• Each entry (i.e. one number string) can have maximum of 16 digits.
• Number string can be a complete telephone number, area code or few initial digits of a telephone number.
• An allowed and a denied list should be assigned to each station depending upon the feature and the
requirement.
• A completed allowed list would look as below:
