About Dial Plan Commands
The following list contains rules for CiscoATA dial plans:
•. —Wildcard, match any digit entered.
•- —Additional digits can be entered. This command can be used only at the end of a di al plan rule
(for example, 1408t5- is legal usage of the - command, but 1408 t5-3... is illegal).
•>#—Defines the # character as a termination character. When the termination character is entered,
the dial string is automatically sent. The termination character can be entered only after at least one
user-entered digit matches a dial plan rule. Alternatively, the command >* can be used to define *
as the termination character.
•tn— Defines the timeout value n, in the unit of seconds, for the interdigit timer. Valid values are 0-9 and
a-z, where a-z indicates a range of 10 to 36.
•rn—Repeat the last pattern n times, where n is 0-9 or a-z. The values a-z indicate a range of 10 to
36. Use the repeat modifier to specify more rules in less space.
Note The commands ># and tn are modifiers, not patterns, and are ignored by the rn command.
•|—Used to separate multiple dial plan rules.
•^—Logical not. Match any character except the character immediately following the ^ command.
•S—Seize rule matching. If a dial plan rule matches the sequence of digits entered by the user to this
point, and the modifier S is the next command in the dial plan rule, all other rules are negated for
the remainder of the call (for example, a dial pl an beginning with *S will be the only one in effect
if the user first enters the * key).
Note All rules apply in the order listed (whichever rule is completely matched first will immediately send the
dial string).
Note No syntax check is performed by the actual implementation. The administrator has the responsibility of
making sure that the dial plan is syntactically valid.

Dial Plan Example 1 (Default Dial Plan)

The following dial plan:
*St4-|#St4-|911|1>#t8.r9t2-|0>#t811.rat4-|^1t4>#.-
consists of the following rules:
•*St4-—If the first digit entered is *, all other dial plan rules are voided. Additional digits can be
entered after the initial * digit, and the timeout before automatic dial string send is four seconds.
•#St4—Same as above, except with # as the initial digit entered.
•911—If the dial string 911 is entered, send it immediately.
•1>#t8.r9t2—If the first digit entered is 1, the timeout before automatic send is eight seconds. The
terminating character # can be entered at any time to manually send the dial string. After the 11th
digit is entered, the timeout before an automatic send changes to two seconds. The user can enter
more digits until the dial string is sent by the timeout or by the user entering the # character.
