Handle Directory Numbers
A directory number is a number that is assigned:
• A line position, i.e. an extension or an external line (trunk)
• A facility group number, ACD number etc.
Directory numbers can have 2, 3 or 4 digits. All persons assigned a
directory number can be called from extensions in the system.
Each facility or hardware unit is assigned one directory number
only. All directory numbers can be assigned a name.
Directory numbers are stored as:
• Internal (all directory numbers) or
• External (Common Abbreviated Numbers)
Note: Directory numbers cannot be incompatible, for
example, directory numbers 200 and 2000 cannot exist at
the same time.
On initiation of the system, extensions and trunks are assigned
directory numbers automatically:
• Extensions are assigned numbers from 200 and upwards.
• Trunks are assigned numbers from 700 and upwards.
• All trunks are placed in one route and are assigned directory
number 0.
• If the system has an Dialog 4224 Operator / Dialog 3214,
directory number 9 will be assigned as internal call number to
the operator queue.
