A user has asked you to configure an IP phone PIN so that the user can circumvent afterhours call blocking
restrictions.
Which of the following PINs will the CME router not accept? (Select 2 choices.)

A.
123

B.
4312

C.
5670192

D.
12943560112

E.
34872345

Explanation:
The Cisco Unified Communications Manager Express (CME) router will not accept a personal identification
number (PIN) of 123, because that PIN is too short. In addition, the CME router will not accept a PIN of
12943560112, because that PIN is too long. CME administrations can issue the pin number command in
ephone configuration mode to configure a specific IP phone with a PIN. The number parameter accepts a
numeric string with a length in the range from four digits through eight digits. Therefore, you cannot configure a
PIN of less than four digits nor can you configure a PIN of more than eight digits.
When an ephone is configured with a PIN, that PIN can be used to circumvent any afterhours calling
restrictions that have been placed on the ephone. Afterhours calling restrictions are typically used to prevent
certain types of calls from taking place during a specifically defined time period. For example, you could
configure a calling restriction that prevents calls to longdistance numbers from the time your company closes
for the day until the time it reopens for the next business day.
