5-6 AltiContact Manager Administration Manual
Description
The number of digits needed to match a DID (Direct Inward
Dialing) number, with a range of 2 - 16.
Each extension can be assigned a DID number. A DID
number does not have a fixed length. For example, the DID
number length is 4; the extension DID number - 2529299.
Depending on the service contract with the Central Office
(CO), the DID trunk can send all 7 digits (2522999) or just
the last 4 digits (2999). If this DID Number Length option
is set to 4, the system always tries to match the last 4 digits
received to the last 4 digits of a DID number, regardless of
what is received.
Note: To accommodate future growth and minimize
disturbance, it is recommended that the length of the DID
numbers assigned to an extension be greater than or equal to
this DID Number Length. However, it is not necessary to
use the DID Number Length when routing via tie trunks.
These define how the system responds to the first digit
dialed by the user. If a particular digit is grayed out—not
available—that means it cannot be used in the country
location selected in the General window.
The drop-down list options for each digit are as follows:
—
Extension
—
Trunk Access
—
Feature Access
—
Operator
—
Invalid (no action)
—
IP Trunk Access
—
Route Access
