LOCAL DIAL PLAN AND PATTERN MATCHING
Pattern matching is only functional when a line is seized before the number is dialed (i.e. when
a user dials by selecting a line/going off hook before entering the number or if the user dials by
any method with the live dialpad feature enabled) or when dialing using a Speeddial key.
Note: For more information on the live dialpad feature, see
