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.

Examples

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

• [0-9].....$
  • 6 Digit Phone Numbers (like internal extensions)
• [2-9]..[2-9]......$
  • 10 Digit Phone Numbers following North American Numbering Plan
