Using Dial Plans
Interdigit Timer Master Override
The long and short interdigit timers can be changed in the dial plan (affecting a specific line) by
preceding the entire plan with the following syntax:
• Long interdigit timer: L : delay-value ,
• Short interdigit timer: S : delay-value ,
Thus, “L:8,( . . . )” would set the interdigit long timeout to 8 seconds for the line associated with this
dial plan. And, “L:8,S:4,( . . . )” would override both the long and the short time-out values.
Local Timer Overrides
The long and short time-out values can be changed for a particular sequence starting at a particular point
in the sequence. The syntax for long timer override is: “L delay-value<space>“. Note the terminating
space character. The specified delay-value is measured in seconds. Similarly, to change the short timer
override, use: S delay-value<space>.
Pause
A sequence may require an explicit pause of some duration before continuing to dial digits, in order for
the sequence to match. The syntax for this is similar to the timer override syntax: P delay-value <space>.
The delay-value is measured in seconds.
This syntax allows for the implementation of Hot-Line and Warm-Line services. To achieve this, one
sequence in the plan must start with a pause, with a 0 delay for a Hot Line, and a non-zero delay for a
Warm Line.
Implicit Sequences
The SPA9000 implicitly appends the vertical code sequences entered in the administration web server
Regional parameter settings to the end of the dial plan for both Line 1 and Line 2. Likewise, if
<Enable_IP_Dialing> is enabled, then IP dialing is also accepted on the associated line.
Dial Plan Examples
The following dial plan accepts only US-style 1 + area-code + local-number, with no restrictions on the
area code and number:
( 1 xxx xxxxxxx )
The following also allows 7-digit US-style dialing, and automatically inserts a 1 + 212 (local area code)
in the transmitted number.
( 1 xxx xxxxxxx | <:1212> xxxxxxx )
For an office environment, the following plan requires a user to dial 8 as a prefix for local calls and 9 as
a prefix for long distance. In either case, an “outside line” tone is played after the initial 8 or 9, and
neither prefix is transmitted when initiating the call.
( <9,:> 1 xxx xxxxxxx | <8,:1212> xxxxxxx )
The following allows only placing international calls (011 call), with an arbitrary number of digits past
a required 5 digit minimum, and also allows calling an international call operator (00). In addition, it
lengthens the default short interdigit timeout to 4 seconds.
S:4, ( 00 | 011 xxxxx x. )
