Examine the output, and use the information you gather to answer the question.
You issue the prefix 911 command on the CME router.
Which of the following will occur when a user dials 411?
A.
The user will be connected to the 411 service with an outbound prefix of 9.
B.
The user will be connected to the 411 service directly.
C.
The user will be connected to the extension 9114 if it exists.
D.
The user will be connected to an operator.
Explanation:
If you issue the prefix 911 command on the Cisco Unified Communications Manager Express (CME) router, a
user who dials 411 will be connected to the extension 9114 if it exists in the system. The prefix command is
used to add one or more digits to the front of the dial string before the dial string is forwarded to the destinationnetwork. Issuing the prefix 911 command in this scenario will add 911 to the front of the dial string. The last two
digits in the destination pattern, 1 and 1, were explicitly matched. By default, CME only forwards digits matched
by wildcards in a destination pattern, not digits that are explicitly defined in the destination pattern. Therefore,
the dial string 9114 would be forwarded to the public switched telephone network (PSTN).
The destination-pattern command is used to match both inbound and outbound dial peers. The sequence of
dialed digits that will be matched for a dial peer can contain the digits 0 through 9, the asterisk (*), and the
pound sign (#). In addition, you can use a period (.) as a wildcard symbol to refine the dialing pattern or to
match multiple dial strings for a single dial peer. The command set in this scenario configures a dial peer on a
CME router to explicitly match the pattern 9114. By default, CME only forwards digits matched by wildcards in a
destination pattern, not digits that are explicitly defined in the destination pattern. Therefore, the destinationpattern .11 command configures CME to forward only the first of the digits in the destination pattern when a
caller dials 411.Cisco: Cisco IOS Voice Command Reference: prefix
