What does a period accomplish when it is used in a SIP Dial Rule pattern that is associated with a Cisco 9971 IP Phone that is registered to Cisco Unified Communications Manager?
A. It matches any single digit from 0 to 9.
B. It matches one or more digits from 0 to 9.
C. It is a delimiter and has no significant dialing impact.
D. It matches any single digit from 0 to 9, or the asterisk (*) or pound (#) symbols.
E. It matches one or more digits from 0 to 9, or the asterisk (*) or pound (#) symbols.
Correct Answer: D
Explanation/Reference:
Explanation:
Asterisk (*) matches one or more characters. The * gets processed as a wildcard character. You can override this by preceding the * with a backward slash (\) escape sequence, which results in the sequence \*. The phone automatically strips the \, so it does not appear in the outgoing dial string. When * is received as a dial digit, it gets matched by the wildcard characters * and period (.).
