Directory Loose Number Matching - Mitel 6800 Series Administrator's Manual

Mitel 6800 Series SIP Phone Release 4.2.0 SP2 Administrator Guide

DIRECTORY LOOSE NUMBER MATCHING

By default, if an incoming call's phone number is identical to a phone number corresponding
to a directory entry, the phone will automatically display the name defined for the respective
directory entry instead of the information provided in the SIP header (e.g. From, To, Contact,
PAI info). If the phone number is not identical, the directory lookup will fail and the phone will
not display the stored directory entry's name.
However, the phone supports a directory loose number matching feature (using the "directory
digits match" configuration parameter) whereby the Administrator can define how many digits
of an incoming call's phone number the phone will use to perform a lookup in the various
directories. For example, if a directory contains "1234567" as a phone number for an entry with
the name defined as "John Smith", and the "directory digits match" parameter is defined as
"7", the phone will take the last 7 digits of the incoming number and perform a lookup in the
various directories. If an incoming call's phone number is 5551234567, as the last 7 digits are
a match, the phone will display the directory entry's name (i.e. John Smith) on screen.
In previous releases, the value defined for the "directory digits match" parameter
corresponded to the maximum number of digits the phone would take into account to perform
the directory lookup. This means, using the example above, if an incoming call's phone number
was 4567, the phone would still match the incoming call to the "John Smith" directory entry with
the number "1234567". Starting with Release 4.2.0 SP1, the value defined for the "directory
digits match" configuration parameter corresponds to the minimum number of digits the phone
will take into account to perform a directory lookup. If the incoming call's phone number is less
than the value defined for the "directory digits match" parameter, the phone will not perform
a directory lookup and will display the information provided in the SIP header.
