Configuring a Dial Plan
The time-out duration depends on the matching state. If no candidate sequences are as yet complete (as
dialed), the Interdigit_Long_Timeout applies. If a candidate sequence is complete, but there exists one
or more incomplete candidates, the <Interdigit_Short_Timeout> applies.
If you are using the SPA9000, enter 9 > *69 to callback and call return.
Table 3-5 describes the entries to use when programming the dial plan.

Dial Plan Rules
This section describes the rules that apply to configuring and interpreting dial plans.
Note White space in a dial plan script is ignored, but it may be used for readability.
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:
• Individual keys 0, 1, 2 . . . 9, *, #.
• The letter x matches any one numeric digit (0 .. 9)
• A subset of keys within brackets (allows ranges): for example, [389] means 3 or 8 or 9)
– Numeric ranges (n-n) are allowed within the brackets: for example, [2-9] means any digit from
2 through 9)
– Ranges can be combined with other keys: e.g. [235-8*] means 2 or 3 or 5 or 6 or 7 or 8 or *.
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”.
