Use the Automatic Number Identification (ANI) and Information Indicator Digits (II-digits) Call Vectoring features to make vector routing decisions based on the caller identity and the originating line. Use Caller Information Forwarding (CINFO) to collect Caller Entered Digits (CED) and Customer Database Provided Digits (CDPD) for a call from the network.

Avaya uses the term ANI to denote both ANI and Calling Line Identification (CLID) which can be used interchangeably within Vectoring. ANI and II-digits, when provided with an incoming call to a VDN, are sent to Call Management System (CMS) when vector processing starts. ANI, II-digits, and CINFO are forwarded with interflowed calls. ANI and II-digits are also passed over the Adjunct Switch Application Interface (ASAI) in event reports.
