You have a Cisco CME router with CUE installed. You want to configure the router so that the MWI light will
turn on when a user receives a voice mail message. All of the users have four-digit extensions.
You issue the following commands on the router:
ephone-dn 1
mwi on
Which of the following commands could you issue to complete the configuration? (Select the best answer.)
A.
number *1
B.
number ….
C.
number 601
D.
number 6001….
E.
number 6001 ….
F.
number *1 ….
Explanation:
You could issue the number 6001.…command to complete the configuration so that the message waiting
indicator (MWI) light will turn on when a user receives a voice mail message. The number command is used to
create the code that Cisco Unity Express (CUE) sends to Cisco Unified Communications Manager Express
(CME) whenever a user receives a voice mail message.
To configure MWI, you must create two ephonedns: one ephonedn to turn the MWI light on when the user
receives a message, and one ephonedn to turn the MWI light off when the user retrieves all of his or her
messages. When CUE receives a voice mail message for a user, CUE will send a code to the CME router to
indicate that the user’s MWI light should be turned on. When the user retrieves the message, CUE will send
another code to CME to indicate that the user’s MWI light should be turned off.
The MWI codes can be any number of any length, as long as they are not the same as any existing extension
numbers. To configure the MWI code that CUE will send to CME, you should issue the number command with
the MWI code plus a number of periods equal to the number of digits in the users’ extensions. For example, if
you want to create MWI code 6001 and your system is configured to use four-digit extensions, you should issue
the number 6001…. command in ephonedn configuration mode.
Finally, the ephonedn that is configured with the MWI code must also be configured with the mwi on or the mwi
off command, depending on whether the ephonedn should be responsible for turning the MWI light on or off,
respectively. For example, the following command set configures ephonedn 1 to turn on the MWI light for any
fourdigit extension that is prefaced by the MWI code 6001: ephonedn 1
number 6001….
mwi on
Similarly, the following command set configures ephonedn 2 to turn off the MWI light for any fourdigit extension
that is prefaced by the MWI code 6002:
ephonedn 2
number 6002….
mwi off
After CME receives a dialed string from CUE that contains the MWI code, CME will match the dialed digits to
the ephonedn number pattern, strip off the explicitly matched MWI code, and change the state of the MWI light
for the extension that matches the remaining forwarded digits. For example, in this scenario, CUE will send the
digit string 60017777 to CME when the user at extension 7777 receives a voice mail message? CME will then
strip off MWI code 6001 and turn on the MWI light for extension 7777.
You should not issue the number *1 command to complete the configuration. Although the number *1
command would configure ephonedn 1 to use the digits *1 to turn on the MWI light for an IP phone, the
command does not define an extension number pattern. Therefore, the MWI light would not turn on for any
phone extension.
You should not issue the number 601 command to complete the configuration. Although the number 601
command would configure ephonedn 1 to use the digits 601 to turn on the MWI light for an IP phone, the
command does not define an extension number pattern. Therefore, the MWI light would not turn on for any
phone extension.
You should not issue the number …. command to complete the configuration. Although the number
….command would configure ephonedn 1 with a fourdigit extension number pattern, no MWI code would be
explicitly defined. Therefore, dialing any fourdigit extension would cause CUE to simply dial the user’s
extension? it would not turn on the MWI light on a user’s phone.
You should issue neither the number *1 …. nor the number 6001 …. command to complete the
configuration. Unless you separate the extension numbers by using the secondary keyword, you cannot issue
the number command with more than one extension number parameter? the MWI code and the extension
number pattern should be typed together without a space between them.Reference:
