Terminating Event
Dialed digits exactly match one sequence in the dial
plan.
A timeout occurs.
A user presses the # key or the dial softkey on the IP
phone screen.
Dial Plan Timer (Off-Hook Timer)
You can think of the Dial Plan Timer as the off-hook timer. This timer starts when the phone goes off hook.
If no digits are dialed within the specified number of seconds, the timer expires and the null entry is evaluated.
Unless you have a special dial plan string to allow a null entry, the call is rejected. The default length of the
Dial Plan Timer is 5 seconds.
Syntax for the Dial Plan Timer
SYNTAX: (Ps<:n> | dial plan)
• s: The number of seconds; if no number is entered after P, the default timer of 5 seconds applies. With
the timer set to 0 seconds, the call transmits automatically to the specified extension when the phone
goes off hook.
• n: (optional): The number to transmit automatically when the timer expires; you can enter an extension
number or a DID number. No wildcard characters are allowed because the number is transmitted as
shown. If you omit the number substitution, <:n>, the user hears a reorder (fast busy) tone after the
specified number of seconds.
Examples for the Dial Plan Timer
Allow more time for users to start dialing after taking a phone off hook:
(P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
Processing
If the dial plan allows the sequence, the number is
accepted and is transmitted according to the dial plan.
If the dial plan blocks the sequence, the number is
rejected.
The number is rejected if the dialed digits are not
matched to a digit sequence in the dial plan within
the time that the applicable interdigit timer specifies.
The Interdigit Long Timer applies when the dialed
digits do not match any digit sequence in the dial plan.
Default: 10 seconds.
The Interdigit Short Timer applies when the dialed
digits match one or more candidate sequences in the
dial plan. Default: 3 seconds.
If the sequence is complete and is allowed by the dial
plan, the number is accepted and is transmitted
according to the dial plan.
If the sequence is incomplete or is blocked by the dial
plan, the number is rejected.
