ani - Computer Definition
A feature of the public switched telephone network (PSTN) that transmits the originating telephone number in advance of connecting the call. ANI is used by telephone companies for tracking and billing purposes. PBXs equipped with proper software and with special trunking arrangements (all at additional cost) can appear to the network as a central office (CO) switch and, therefore, can gain access to ANI information. This approach offers advantages compared to calling line identification (CLID), which the callers can block, and is often used by incoming call centers. ANI is available to interexchange carriers (IXCs) subscribing to Feature Group D (FGD) termination. See also CLID, CO, FG, IXC, and PSTN.

(2) (Automatic Number Identification) A telephone service that transmits the billing number (BN) and the telephone number of the incoming call. ANI identifies the calling party for toll call billing and enables the call to be routed to the appropriate long distance service provider. ISDN supports ANI by carrying the calling telephone number in the D channel. ACD systems use the billing number to query a database and retrieve the customer's records. See Caller ID, ACD and CNAM.
