End User Telephony and Mobility Features Flashcards
(Includes Configuring Mobility Features)
What CUCM feature allows users to log into any IP phone and have their individual configuration applied to the phone?
Extension Mobility
What is the term for where users’ Extension Mobility configurations is stored?
Device profiles
Name the three options that can be applied when an Extension Mobility user attempts to login at another phone.
Allow multiple logins (calls to the user ring on both phones)
Deny
Auto-logout (from the first phone)
Name the configuration that is applied to an IP phone when no Extension Mobility users are logged in.
A logout profile
What softkey(s) should Extension Mobility users press to login?
The Services softkey
Extension Mobility users have device profiles assigned to their account for each phone type. What happens if a user logs into a phone type for which they have no assigned device profile?
The phone will use the default device profile for that phone type.
What is the term for a one-way intercom call?
Whisper intercom
Name two important things to keep in mind about what happens when a user is on a call and receives an intercom call.
- The first call is maintained.
2. The person on the other line of the first call cannot hear the intercom caller.
List the seven steps required to enable Extension Mobility in CUCM.
- Activate the EM service.
- Configure EM service parameters.
- Add EM as a phone service.
- Create a default device profile for each phone model.
- Create device profiles that are subscribed to the EM service.
- Associate end users with EM-subscribed device profiles.
- Enable EM for phones and subscribe them to the service.
Name two common Extension Mobility service parameters.
Maximum login time
Multiple login behavior
Where in the CUCM menus would one go to activate the Extension Mobility service?
Device > Device Settings > Phone Services
What will happen if an admin fails to subscribe both the device profile and the IP phone to the Extension Mobility service?
The user won’t have access to EM after logging in and won’t be able to logout.
What happens when a user logs into an IP phone using Extension Mobility and multiple device profiles are assigned to the user?
The user is prompted to choose a device profile.
When configuring the Extension Mobility service, what option can one choose to reduce additional configuration requirements? What does this option do?
Select the Enterprise Subscription checkbox. This automatically subscribes all device profiles and IP phones to the EM service.
Where in the CUCM menus would one go to create default device profiles?
Device > Device Settings > Default Device Profile
When a user initiates an intercom session with another user, is the call initially one-way or two-way?
One-way. The recipient can hear the sender.
Name the two ways intercom can be configured on an IP phone.
- Speed dial
2. Intercom softkey, which requires dialing the extension
What happens if a user is on the phone and attempts to turn a whisper intercom into a two-way call?
The first call is dropped.
List the three steps in configuring intercom on CUCM.
- Create intercom partitions
- Configure intercom CSSs
- Create intercom directory numbers
In what section of CUCM are intercom partitions and CSSs configured?
Call Routing > Intercom > Intercom Route Partition
Call Routing > Intercom > Intercom Calling Search Space
What also happens when an intercom partition is created?
An intercom CSS is automatically created to match it.
Why would one need to make changes to intercom CSS configurations?
To allow an intercom user to support multiple intercom targets or to limit the number of targets available to the intercom user.
Name the four things required to create an intercom directory number in CUCM.
- Create a phone button template with an intercom line.
- Apply the template to a device.
- Add an intercom DN to the device configuration.
- Apply an intercom partition and CSS to the DN.
Give the commands to create ephone-DN #60 in CME as an intercom line to extension A101, listed as Manager. The local extension should be A100.
(config)# ephone-dn 60
(config-ephone-dn)# number A100
(config-ephone-dn)# intercom A101 label “Manager”
Name the command switches that can be paired with the intercom command in CME to:
- Place an existing call on hold when the intercom call comes in.
- Ring rather than automatically put the intercom call through.
- Answer as a two-way call.
- barge-in
- no-auto-answer
- no-mute
Give the commands to apply the intercom ephone-DN #60 to button #2 on ephone #1.
(config)# ephone 1
(config-ephone)# button 2:60
(config-ephone)# restart
This call forwarding type forwards all calls unconditionally.
CFA (Call Forward All)
This call forwarding type forwards calls that are received when the IP phone is in use.
CFB (Call Forward Busy)
This call forwarding type forwards calls if the call is not picked up within a specific period of time.
CFNA (Call Forward No Answer)
This call forwarding type forwards calls when a call is sent to a hunt pilot that is temporarily unavailable.
CFNC (Call Forward No Coverage)
This call forwarding type forwards calls when no device with the configured directory number has registered with CUCM.
CFUR (Call Forward Unregistered)
How do call permissions changed if all calls are being forwarded from a line?
The Call Forwarding Search Space is used instead of the normal CSS.
Give the commands required to tell CME to forward unanswered calls to DN 21 to extension 1600 after 25 seconds.
(config)# ephone-dn 21
(config-ephone-dn)# call-forward noan 1600 timeout 25
How long are rings and the spaces between rings in the USA?
Rings are 2 seconds; the spaces are 4 seconds.
Give the DN command that makes call forwarding unavailable on CME. What is this command normally used for?
(config-ephone-dn)# call-forward max-length 0
It usually limits the length of the forwarding string.
What complication in call forwarding does the H.450.3 standard address? How?
Hairpinning. It signals the originator of the IP call to send the call to another number instead of forwarding the RTP itself.
Give the command that tells CME to enable H.450.3 for all four-digit extensions beginning with 15.
(config-telephony)# call-forward pattern 15..
What will happen if the same DN is applied to multiple IP phones in the same partition?
All the phones will ring when the number is dialed (this is called a shared line)
Name and briefly describe the two barge modes. Name the softkeys that activate each.
- Built-in conference bridge on the target device (the one being barged). Activated using the Barge softkey.
- Shared conference bridge. Activated using the cBarge softkey.
Which of the two barge modes has a set limit on the number of media streams in the barge session? What is the limit?
The built-in conference bridge has a limit of three streams.
What feature limits the ability of shared line users to activate the barge feature? Where is this enabled, and is it on by default?
The Privacy feature is set (globally or locally) by an administrator in the service parameters, then activated by the user pressing the Privacy softkey. Default is enabled.
Name the two key facts about how the standard Call Pickup feature works.
- Phones are assigned to a Call Pickup group.
- When a user wants to answer another call in their group, they press the Call Pickup softkey and the call is sent immediately to that phone.
Name the two basic facts about the Group Call Pickup feature.
- DNs are placed in separate Call Pickup groups.
2. To answer another phone, the user presses the GPickup softkey and dials the group number of the ringing DN.
How does Directed Call Pickup differ from Group Call Pickup?
Directed Call Pickup (a variant of Group Call Pickup) requires the user to dial the DN that is ringing, rather than the group number.
List the two basic facts about Other Group Call Pickup.
- Call Pickup groups are associated with each other.
- The user presses the OGroup (or OPickUp) softkey to answer a call to a DN in any of the associated Call Pickup groups.
What CUCM service parameter must be activated for Call Pickup to function?
Auto Call Pickup Enabled.
Where does one go in CUCM to configure Call Pickup groups?
Call Routing > Call Pickup Group
What’s the configuration restriction for Other Group Pickup?
Group associations must be configured during the initial configuration of a pickup group.
Out of standard Call Pickup, Group Call Pickup, and Other Group Pickup, which are supported on CME?
All of them.
Give the commands that configure CME DN #20 for Call Pickup group 5500.
(config)# ephone-dn 20
(config-ephone-dn)# pickup-group 5500
