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 switch 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.
Pass Prefixed CPN to ASAI
Passes Calling Party Number information (CPN) to ASAI. The prefixed number is
not passed on to other adjuncts, Call Detail Recording, or switches.
