EPhone

Here you will find answers to EPhone Questions

Question 1

Refer to the exhibit.

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.

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

Explanation

The park softkey is displayed on your phone only if you have created at least one park slot for your Cisco CME system. When you press the park softkey, the call is transferred to a park slot that has the number that most closely matches the extension number you used to answer the call. So if you are using extension 5001 and you park a call from that extension, the call is parked in a park slot with a number ending in 001 if available. For example, if you create park slots with numbers 6000, 6001, 6002, and 6003, a call parked from extension 5001 uses park slot 6001 if possible. If no park slot with a matching number is available, any available park slot is used.

When you park a call, the park-slot number selected is displayed on your IP phone’s display. To retrieve a parked call, simply press the pickup softkey followed by the park-slot number. To retrieve the last call parked by your phone (or notified to your phone), simply press the pickup softkey followed by the star (*) key on the phone’s keypad.

In short, the command park-slot timeout 10 limit 3 notify 5001 will create a park slot instance with number 5001. It sets the reminder interval to 10 seconds and configures 3 as the maximum number of reminders. As soon as the maximum number of reminders has been sent (after 3 * 10 = 30 seconds), the call in the park slot is disconnected. Each time the reminder interval is reached, a reminder notification is sent to all IP phones with extension 5001.

After you have created your first park slot within your Cisco CME system, you need to reset or restart your IP phone(s) before the park softkey becomes visible on the phone.

Question 3

Refer to the exhibit.

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:

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

Explanation

We can see in both ephone-dns 13 & 14 the number 1003 command is used. It means that if someone dials 1003, one of the two phones will ring. If we don’t assign different priorities on these 2 phones, the CME system will pick one completely at random so sometimes ephone 4 will get the call and sometimes ephone 5 will get the call.

To gain more control over how the call flows than a random line selection, we can use the preference command. This command dictates which ephone-dn is more preferred than the other by assigning a value from 0 to 10, where the lower preference numbers are better. So in the exhibit, if we ignore the “no huntstop” command (will be explained later), the ephone 4 will always ring first because the default preference value is 0 which is lower than the preference value of ephone-dn 14 (preference 1). The ephone 5 will ring only if the ephone 4 is currently busy. But this system will make the person on phone 4 very busy while the one on phone 5 idle.

A better system might have all the IP phones ring when on a call to 1003 and whoever picks up the phone first will answer the call. This is where the “no huntstop” comes into play.

The “no huntstop” command tells the CME system, “continue hunting for other matches with this ephone-dn”. And the system finds out the ephone-dn 14 has the number 1003 configured -> The system will ring phone 5 too.
