Cisco Unified Border Element (CUBE) Dial-Peer Destination Patterns

Helpful Symbols

.
- Indicates a single-digit placeholder. For example, 555.... matches any dialed string beginning with 555, plus at least four additional digits.
[]
- Indicates a range of digits. A consecutive range is indicated with a hyphen (-). A nonconsecutive range is indicated with a comma (,); for example, [5,8].
()
- Indicates a pattern; for example, 408(555). It is used in conjunction with the symbol ?, %, or +.
?
- Indicates that the preceding digit occurred zero or one time. Enter ctrl-v before entering ? from the keyboard.
%
- Indicates that the preceding digit occurred zero or more times. This functions the same as the "*" used in regular expression.
+
- Indicates that the preceding digit occurred one or more times.
T
- Indicates the interdigit timeout. The router pauses to collect additional dialed digits.
* and #
- These characters on standard touch-tone dial pads can be used anywhere in the pattern.
$
- Disables variable-length matching. It must be used at the end of the dial string.
^
- When used within brackets, allows one to eliminate a digit from consideration for dial-peer matching purposes.

I cannot stress this enough, use the $ sign to eliminate unexpected matching.
