The following list contains rules for Cisco ATA dial plans:
•. —Wildcard, match any digit entered.
•- —Additional digits can be entered. This command can be used only at the end of a dial plan rule (for example, 1408t5- is legal usage of the - command, but 1408t5-3... 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.
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 plan beginning with *S will be the only one in effect if the user first enters the * key).
All rules apply in the order listed (whichever rule is completely matched first will immediately send the dial string).
No syntax check is performed by the actual implementation. The administrator has the responsibility of making sure that the dial plan is syntactically valid.
