    CCNA Voice Bible (640-460) – EPhone

    By admin | July 10, 2010

    Question 1

    Refer to the exhibit.

    UCME#show ephone
    ephone-1 Mac:0000.94C2.8A44 TCP socket:[2] activeLine:0 REGISTERED in SCCP ver 1 1 and Server in ver 8
    mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8

    button 2: dn 3 number 5010 CH1    IDLE    CH2    IDLE
    ephone-2 Mac:0003.E3C4.463C TCP socket:[-1] activeLine:0 DECEASED

    button 1: dn 2 number 5002 CH1    DOWN    CH2    DOWN
    button 2: dn 3 number 5010 CH1    IDLE       CH2    IDLE    shared

    What information can be gleaned from the output of the show ephone command?

    A. There are two registered IP phones. Shared number 5010 on line 2. Message waiting on line 1 of phone 1.
    B. There are two registered IP phones. Shared number 5010 on line 2. Message waiting on shared line.
    C. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2. Message waiting on shared line.
    D. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2. Message waiting on line 1 of phone 1.
    E. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2 of phone 2. Message waiting on line 2 of phone 1.
    Answer: D

    Explanation:

    The first Ephone’s status (ephone-1) is REGISTERED so we can confirm this ephone has been registered. The second one (ephone-2) shows DECEASED, it means that the CME router has lost connectivity with this IP Phone through a TCP keepalive failure.

    Notice: The status UNREGISTERED indicates the CME router closed the connection to the IP phone in a normal manner.

    Question 2

    Refer to the exhibit.

    telephony-service
    no auto-reg-ephone
    max-ephones 2
    max- dn 10
    ip source-address 10.3.130.1 port 2000
    max-conferences 8 gain -6
    moh music-on-hold.au
    multicast moh 239.1.1.1 port 2000
    transfer-system full-consult
    create cnf-files version-stamp Jan 01 2002 00:00:00

    ephone-dn 1 dual-line
    number 5001

    ephone-dn 5

    !

    ephone 1
    mac-address 0014.1CBC.E179
    button 1:1

    The configuration for Call Park has been performed by a colleague before going on vacation. Users are complaining that the Call Park softkey does not appear on their phones. What can rectify this issue?

    A. The park-slot number ephone-dn 5 needs to be added as a line to one of the ephone 1 buttons.
    B. The phones need to be restarted.
    C. The park-slot number should be outside the range of 5XXX numbers.
    D. The call-park command enable needs to be added under telephony-service.

    Answer: B

    Question 3

    Refer to the exhibit.

    ephone-dn 21
    number 2001
    paging ip 239.0.1.21 port 2000

    ephone-dn 22
    number 2002
    paging ip 239.0.2.22 port 2000
    < missing-command >

    ephone 1
    paging-dn 20
    ephone 2
    paging-dn 20
    ephone 3
    paging-dn 21
    ephone 4
    paging-dn 21

    When a call is placed to 2000, phones 1 and 2 are paged. A call to 2001 pages phones 3 and 4.
    What command is missing so that a call to 2002 pages all four phones?

    A. Paging group 20 21
    B. Paging group 10 20 30 40
    C. Paging group all
    D. Paging group 2000 2001 2002
    E. Paging group ephones-all

    Answer: A

    Explanation:

    In fact, the exhibit should show the configuration of ephone-dn 20, something like this:

    ephone-dn 20
    number 2000
    paging ip 239.0.1.21 port 2000

    To page all four phones which belong to group 20 & 21, we just need to assign these two groups to a number. The full command is:

    CME_Voice(config-ephone-dn)# paging group 20,21

    Notice:

    - We don’t need to assign any ephones to paging-dn 22 because this ephone-dn represents a group of both paging-dns 20 and 21.

    - The IP address that follows the paging command is a multicast address.

    Question 4

    Which ephone-dn type does the exhibit represent?

    A. Shared ephone-dn
    B. Overlaid ephone-dn
    C. Dual-line ephone-dn
    D. Single-line ephone-dn
    E. Dual-number ephone-dn
    F. Two ephone-dns with one number

    Answer: A

    Explanation:

    Shared line (or shared ephone-dn) means that we assign the same ephone-dn to multiple ephones. Incoming calls to number 1006 will ring on both phones.

    Question 5

    Which ephone-dn type does the exhibit represent?

    A. Shared ephone-dn
    B. Overlaid ephone-dn
    C. Dual-line ephone-dn
    D. Single-line ephone-dn
    E. Dual-number ephone-dn
    F. Two ephone-dns with one number

    Answer: F
