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 Operator, directory number 9 will
be assigned as internal call number to the Operator queue.
Handling of directory numbers via the Executive telephone
is limited to:
• Allocate names to directory numbers
• Read directory numbers
• List directory numbers
• Change position of two extension numbers
Tip! Extensions equipped with a dialog 3213 or dialog 3214
telephone can search the programmed directory numbers (inter-
nal and external) via the "Integrated telephone directory", see the
related user´s guides.
