Parameter Description
First Digit Translator Configuration
Figure 3. 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."
