National CPN Prefix
Allows you to apply prefixes to national calling numbers for display at receiving phones. This is
useful for those phones that use or implement call back features based on incoming call
numbers. When an ISDN-PRI call arrives, the incoming call setup is analyzed for: (1) whether
the Type of Address (TOA) is national or international, and (2) whether the Numbering Plan
Identifier (NPI) is Unknown or ISDN/Telephony. This administered prefix is applied to national
calls. Prefixing applies to any subsequent display on the same server when the call is
transferred, covered, or forwarded. The same prefixing applies to outgoing ISDN-PRI calls
when the connected number information is returned and meets the same TOA and NPI criteria.
The prefix plus the calling/connected number digit string is limited to 15 digits, with truncation
occurring at the least significant digits.
Valid entries
1 to 5 digits, (0 to
9), * and # or
