Configuring a Dial Plan
Intersequence Tones
An “outside line” dial tone can be generated within a sequence by appending a comma (,) between digits.
Thus, the sequence “9, 1xxxxxxxxxx” sounds an “outside line” dial tone after the user presses 9, until
the 1 is pressed.
Number Barring
A sequence can be barred (rejected) by placing a ! character at the end of the sequence. Thus,
“1900xxxxxxx!” automatically rejects all 900 area code numbers from being dialed.
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,( . . . )” sets the interdigit long timeout to 8 seconds for the line associated with this dial plan.
And, “L:8,S:4,( . . . )” overrides both the long and the short time-out values.
Local Timer Overrides
The long and short timeout 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 Linksys IP phone 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, 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 )
