International CPN Prefix
Allows you to apply prefixes to international calling numbers for display at receiving telephones.
This is useful for those telephones 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
international 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.
