You issue the show running-config command on a CME router and receive the following partial output:
Examine the output, and use the information you gather to answer the question.
With no additional configuration, which of the following commands could be issued in place of the destinationpattern .11 command to enable users to dial all N11 numbers?
A.
destination-pattern 9.11
B.
destination-pattern [0-9]11
C.
destination-pattern .T
D.
destination-pattern 9411
E.
destination-pattern 4911
Explanation:
Of the available choices, only the destination-pattern .T command could be issued in place of the destinationpattern .11 command to enable users to dial N11 numbers without any other configuration. The destinationpattern 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 .T wildcard pattern configures the Cisco Unified Communications Manager
Express (CME) router to match every digit the user dials regardless of the length of the string of digits. The
router will wait until the user stops dialing before attempting to route the call. By default, CME only forwards
digits matched by wildcards in a destination pattern, not digits that are explicitly defined in the destination
pattern.
None of the other destination patterns will enable users to dial all N11 numbers without additional configuration,
because all of the remaining choices contain explicit matches. The command set in this scenario configures a
dial peer on a CME router to match the pattern .11. In order to ensure that the N11 digits are forwarded by
CME, you would additionally need to issue the forward-digits 3 command, the forward-digits all command, or
the no digit-strip command on the CME router.Cisco: Cisco IOS Voice Command Reference: destination-pattern
