When an incoming call is given Routing by Dial Plan treatment, if the
programmed service, number of digits in the CdPN, and patterns match those
associated with the incoming call, the appropriate digit deletion and addition
are performed. The process is as follows:
1. The programmed service is compared with the B-channel service, if
supplied. A match is found if the two services are equivalent or if the
programmed service in the Dial Plan Routing Table is “All Services.” If a
match is found, the system continues to search the entry. If no match is
found or if “No Service” is specified, the system skips the entry and
proceeds to the next one. If no service is supplied, the call is matched to
“No Service” table entries.
2. The programmed number of digits is compared with the number of digits
in the actual CdPN. A match is found if the two numbers are equivalent
or if the programmed number of digits is 0. If a match is found, the
system continues to search the entry. If no match is found, the system
skips the entry and proceeds to the next one. If the programmed number
of digits is 0, any number of digits in the CdPN is acceptable.
3. The programmed pattern is compared with the digits associated with the
incoming call. If the pattern matches, the entry is tagged as a possible
best match for the incoming call; it is possible that more than one entry
can match the incoming call. The entry chosen is the one that matches
on the greatest number of digits in the pattern. For example, if 555-2000
is the CdPN and the two patterns that match are 555 and 5552, the entry
associated with 5552 is chosen as the best match. If the pattern is not
programmed, it is considered a match with the number of digits in the
pattern equal to 0.
4. After the table is scanned and the best match is found, the programmed
digit analysis (addition and/or deletion) associated with the entry is
performed. If the digit analysis results in an invalid Dial Plan endpoint,
the call is routed to the endpoint for unassigned DID calls.
