117 Public Dial Plan Digit Analysis
Prerequisite Program: None
This program is used to prevent users from circumventing Destination Restriction (DR) by sending tones
directly to the PSTN before DR analysis is complete. It defines the number of digits expected in PSTN
numbers beginning with identified sequences.
For example, a number starting with the toll prefix “1” would be expected to be 11 digits long. Calls will be
cut through to the public network only after the expected number of digits have been received.
1. In Network eManager, click System > Public Numbering Plan.
2. Enter the Identifying Digits used for external calls.
3. Select Pattern Digit Length. Total digits beginning with the selected Prefix digit.
4. Get Default sets all values to factory default.
5. Click Submit.
