Digit Sequence Examples

The following examples show digit sequences that you can enter in a dial plan.

In a complete dial plan entry, sequences are separated by a pipe character (), and the entire set of sequences is enclosed within parentheses.

EXAMPLE: ( [1-8]xx 9, xxxxxxx 9, <:1>[2-9]xxxxxxxxx 8, <:1212>xxxxxxx 9, 1 [2-9] xxxxxxxxx 9, 1 900 xxxxxxx ! 9, 011xxxxxx. 0 [49]11 )
