Functionality Description
Automatic Number Identification (ANI) information from the
carrier is treated exactly the same as an inbound ICLID (Caller ID)
number. Calls can be routed, placed in the Unanswered Call Table,
sent out to the CTI Module port on a keyset, and run through the
Number To Name Translation Table. The Triad 2 system provides call
progress tones in the same manner as ICLID.
Dialed Number Identification Service (DNIS) information from the
carrier is treated using DID line rules. DNIS calls are routed based on
the DID Routing Table.
ANI/DNIS is a combined format, where the system waits for the ANI/
DNIS information from the carrier. When it is received, the system
routes the call using ICLID processing. If this information is not found
in the ICLID Route Tables, the DNIS information is compared to the
DID table for a match. The call is then routed based on the DID tables.
If a match is not found on either the ANI or DNIS number, the call is
routed based on normal CO line operation (CO Ringing Assignments).
