Parameter Description
DID Number The number of digits needed to match a DID (Direct Inward Dialing)
Length number. The range is from 2 - 16.
Each extension can be assigned a DID number. A DID number does
not have a fixed length. For example, suppose the DID Number
Length is 4 and the extension DID number is 2522999. 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 the
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.
First Digit Translator Configuration
Figure 4-6. Single Digit Routing
To set up a First Digit Translator entry, select the check box (to
the left of 1-9, * or #), then enter the desired digits. When a box is
checked, the digit preprocessor will replace the first digit 1-9, * or
# that user dials with the digits indicated in the corresponding field.
In the above example, if a user dials "*", the system replaces this
with "911".
Note:
This feature is for internal extension users only. It does not
support dialing out from voice mail. Improper configuration
may cause conflict with the system numbering plan. Be sure
to fully test any configuration change in this area before
going "live."
