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
XTS-IP
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).
