Forced Entry of Account Codes and Call Detail Recording
For 94A LSU and 3B2 CDRU 18-word records, authorization codes are output if administered account-code lengths are fewer than six digits. For 59-character records, authorization codes are never recorded. Note that 94A LSU and 3B2 CDRU are no longer supported.
Authorization codes are recorded after destination addresses are dialed. Invalidly dialed authorization codes are recorded, and CDR printouts can be used to determine patterns.
