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 value 
is 5. 
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 is transmitted 
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 will be transmitted as shown. If you omit 
the number substitution, <:n>, then 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:
EXAMPLE: (
P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-
9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9 After taking a phone off hook, a user has 9 seconds to begin dialing. If no 
digits are pressed within 9 seconds, the user hears a reorder (fast busy) 
tone. By setting a longer timer, you allow more time for users to enter the 
digits.
Create a hotline for all sequences on the System Dial Plan:
EXAMPLE: (
P9<:23> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-
9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9<:23> After taking the phone off hook, a user has 9 seconds to begin 
dialing. If no digits are pressed within 9 seconds, the call is transmitted 
automatically to extension 23.
Create a hotline on a line button for an extension:
EXAMPLE: 
( P0 <:1000>)
