Feature description
The In-Band Automatic Number Identification (IANI) feature provides the
ability to display a ten-digit calling party number during setup (signaling)
over a non-Integrated Services Digital Network (ISDN) T1 trunk. The
Automatic Number Identification (ANI) digits are displayed when they auto-
terminate to an Automatic Call Distribution (ACD) Directory Number (DN)
agent telephone with digit display. The IANI feature supports ten digits for
ANI, or three and four digits for Dialed Number Identification (DNIS). IANI
sends these digits to three places: the Call Detail Recording (CDR) records,
the host, and the agent telephone.
When a Direct Inward Dialing (DID) or TIE trunk originates a call, the
software determines whether the call is on an IANI trunk group. If it is, the
ten ANI digits are collected, and the call auto-terminates at the ACD DN
specified for that trunk, provided that the ACD telephone has digit display
and Standard Delayed Display (DDS) Classes of Service. The call, sent by
Dual Tone Multifrequency (DTMF) signaling prior to call termination, is not
received until all the digits are received by the software.
When the call is presented to the ACD DN, a PCI message is simultaneously
sent across the Application Module Link (AML) carrying the ANI digits. The
message contains the ANI number, the ACD DN, and the ACD Agent ID. For
a complete description of ISDN/AP, see Meridian Link ISDN/AP general
guide (553-2901-110).
If an auto-terminating ACD DN is not configured for the trunk, the call
intercepts to the attendant, and the ANI number is displayed on the Attendant
Console. If the call is extended to an ACD DN, the IANI digits are displayed
after it is extended.
