You want to delete 100 unassigned dns from the UCM database.
Which of the following sets of steps could you use? (Select 2 choices.)
A.
Use Bulk Administration > Phones > Delete Phones > Delete Unassigned DN to find and remove the dns.
B.
Use Call Routing > Route Plan Report to find and remove the dns.
C.
Use Call Routing > Directory Number to find and remove the dns.
D.
Use Device > Phone > Directory Number Configuration to find and remove the dns.
E.
Use Device > Phone > Device Information to find and remove the dns.
Explanation:
You could use either Bulk Administration > Phones > Delete Phones > Delete Unassigned DN or Call Routing >
Route Plan Report to find and remove 100 unassigned directory numbers (dns) from the Cisco Unified
Communications Manager (UCM) database. An unassigned dn is a dn that is not associated with a specific
device, such as an IP phone, but that can still be used to forward calls to voice mail or to another dn that is
associated with a device. For UCM to load and use an unassigned dn, the Activecheck box must be selected
for the dn. The Active check box is only displayed for unassigned dns.
The UCM Bulk Administration > Phones > Delete Phones > Delete Unassigned DNwindow automatically
searches for and displays a list of unassigned dns in the UCM database. Once the list of unassigned dns is
complete, you should select the Run Immediately radio button and then click Submit to immediately delete the
unassigned dns from the UCM database.
To find 100 dns by using Call Routing > Route Plan Report, you should choose Unassigned DN from the Find
dropdown menu and then click the Find button. Once the list of unassigned dns is complete, you can select the
check box beside each dn that you want to delete and then click the Delete Selected button to immediately
delete the unassigned dns from the UCM database. Alternatively, you can remove all unassigned dns at once
by clicking the Delete All Found Items button instead of the Delete Selectedbutton.
Problems with unassigned dns can cause an IP phone that is attempting to autoregister with UCM to display the
following error:
Registration Rejected: Error DBConfig
Therefore, you should remove unassigned dns from the autoregistration configuration if this error occurs.
You cannot use Device > Phone > Directory Number Configuration to find and remove 100 unassigned dns
from the UCM database. The Directory Number Configuration window in UCM is for adding dns to an IP phone,
updating dn associations with an IP phone, and removing dns from an IP phone. Although you can add new dns
to the UCM database by using the Directory Number Configuration window, you cannot remove a dn from the
UCM database by using that window. You can also use the Directory Number Configuration window to reassign
dns that have been removed. The Route Plan Report can also be used to accomplish this task.
You cannot use Call Routing > Directory Number to find and remove 100 unassigned dns from the UCM
database. However, similar to Device > Phone > Directory Number Configuration, you can use Call Routing>
Directory Number to add a dn to the UCM database or to update information about the dn in the UCM
database. You can also add a dn to a phone immediately after you add the phone to UCM by clicking the Line
[1] -Add a new DN link or the Line [2] -Add a new DN link in the Association Information area, which is
displayed on the left side of the Phone Configuration window in UCM.
You cannot use Device > Phone > Device Information to find and remove 100 unassigned dns from the UCM
database. However, you can use this option to configure the IP phone Media Access Control (MAC) address,
security profile, device pool, phone button template, location, privacy settings, and mobility mode.https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/bat/8_0_2/bat-802-cm/t03delph.html#wp1355300
