Digit Sequence Syntax

Each digit sequence within the dial plan consists of a series of elements, which are individually
matched to the keys pressed by the user. Elements can be one of the following:
•
•
•

Element Repetition

Any element can be repeated zero or more times by appending a period (.) to the element. Thus,
"01." matches "0", "01", "011", "0111", ... and so on.

Sub-sequence Substitution

A sub-sequence of keys (possibly empty) can be automatically replaced with a different
sub-sequence using an angle bracket notation: < dialed-subsequence : transmitted-subsequence
>. So, for example, "<8:1650>xxxxxxx" would match "85551212" and transmit
"16505551212".

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:
•
•
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.
