You want to configure an alerting name that will be displayed on a caller’s IP phone when the recipient’s IP
phone is ringing.Which of the following fields in UCM Administration should you edit?

A.
the Alerting Name field on the dn configuration page

B.
the Alerting Name field on the phone configuration page

C.
the Alerting Name field on the end user configuration page

D.
the Alerting Name field on the server configuration page

Explanation:
You should edit the Alerting Name field on the directory number (dn) configuration page in Cisco Unified
Communications Manager (UCM) Administration if you want to configure an alerting name that will be displayed
on a caller’s IP phone when the recipient’s IP phone is ringing. For example, if you want the name JOE to be
displayed when a user calls Joe’s extension, you would configure an alerting name of JOE on the dn
configuration page for Joe’s extension. The dn configuration page also contains a variety of other configuration
options, such as the route partition to which the dn belongs and the maximum number of calls.
You should not edit the Alerting Name field on the phone configuration page, because that field does not exist
on that page. The UCM Administration phone configuration page enables you to configure settings specific to a
given IP phone. To identify the IP phone that you are configuring, you should enter the Media Access Control
(MAC) address of the IP phone in the MAC Address field on the phone configuration page. You can also
configure softkey templates and the common device configuration that you want to apply to the IP phone on this
page.
You should not edit the Alerting Name field on the end user configuration page, because that field does not
exist on that page. The UCM Administration end user configuration page enables you to configure settings
specific to a given user. For example, you can configure a user ID, password, and personal identification
number (PIN) on the end user configuration page.
You should not edit the Alerting Name field on the server configuration page, because that field does not exist
on that page. The UCM Administration server configuration page enables you to configure settings such as the
host name or IP address of the server, the IP version 6 (IPv6) name of the server, and a description of the
server.
