ANI Authentication Application Type 2 - Call Flow
ANI Authentication Application Type 2 enables calling subscribers to receive three authentication
types based on the calling number: (1) Authentication with ANI, (2) No ANI case (if no ANI in
coming packet, Tenor AS asks PIN number by prompt) and (3) Incoming packet has the ANI, but
authentication with the ANI fails and Tenor AS prompts for the PIN number.
Figure 6-8 is a diagram of the call flow for ANI Authentication Application Type 2, which details
the messages transmitted between the following components:
Calling Party. The originating caller using a pre-paid calling card.
ANI AUTH Enabled Tenor AS. The Tenor AS which enables the ANI authentication functions.
RADIUS Server. Remote Authentication Dial-In User Service for authenticating with ANI the call-
ing number.
Called Party. The destination called party.
