On-Premises Call Control

Question

An administrator configures international calling on a Cisco UCM cluster and wants to minimize the number of route patterns that are needed. Which route pattern enables the administrator to match variable-length numbers?

Options

  • A9.011@
  • B9.011#
  • C9.011*
  • D9.011!

Explanation

To minimize the number of route patterns for international calling in Cisco UCM and match variable-length numbers, the '!' wildcard character should be used.

Common mistakes.

  • A. The '@' symbol is primarily used in SIP dial plans for domain routing or as part of a URI, not as a wildcard for matching variable-length digits in a numerical route pattern.
  • B. The '#' character is typically used as a call terminator or as part of special feature codes, not as a wildcard for matching a variable number of digits.
  • C. The '*' character is commonly used to match zero or more digits, or as part of feature codes, but '!' is the specific wildcard designed to match one or more digits for variable-length dialing requirements like international numbers.
