Which of the following is true of both the Cisco Unified Personal Communicator and the Cisco Unified Client
Services Framework phone types in UCM?

A.
Device names must begin with UPC.

B.
Device names can be no longer than 15 characters.

C.
Device names can contain uppercase letters only.

D.
Device names can contain numbers and uppercase letters only.

E.
Device names have no naming convention.

Explanation:
Softphone device names can be no longer than 15 characters for both the Cisco Unified Personal
Communicator and the Cisco Unified Client Services Framework phone types in Cisco Unified Communications
Manager (UCM). A softphone is software that behaves like a phone, enabling a user to have voice
conversations over a typical workstation network connection. Softphone mode is an operational mode that
Unified Personal Communicator uses to act as a softphone. In order to use Unified Personal Communicator as
a softphone with UCM, you must add a device to UCM that enables the registration of Unified Personal
Communicator in softphone mode.
The Cisco Unified Personal Communicator device type naming convention requires that the name begin with
the letters UPC and be derived from the UCM user name. The Cisco Unified Client Services Framework device
type name has no such naming convention. However, neither the Cisco Unified Personal Communicator device
type name nor the Cisco Unified Client Services Framework device type name can exceed 15 characters. In
addition, the Cisco Unified Personal Communicator device type cannot contain characters other than
uppercase letters and numbers. By contrast, Cisco Unified Client Services Framework device type names can
contain uppercase letters, lowercase letters, and numbers.
For example, if you were to configure the user Joe Public with a UCM user name of jpublic, the softphone
device name associated with the Cisco Unified Personal Communicator device type would be UPCJPUBLIC.Similarly, the user name of j_public or j.public would have an associated softphone device name of
UPCJPUBLIC. If two UCM user names are similar enough to result in identical softphone device names,
softphone registration problems can occur in UCM. Therefore, it is important to be aware of the Cisco Unified
Personal Communicator naming convention when you are assigning user names and configuring softphone
devices.
You can configure a softphone device in UCM by clicking Device > Phone > Add New in the UCM
administrative graphical user interface (GUI) and selecting either Cisco Unified Personal Communicator or
Cisco Unified Client Services Framework from the Phone Type dropdown field. You must configure the Phone
Type field with Cisco Unified Personal Communicator if the user is using Unified Personal Communicator
version 7.0. You must configure the Phone Type field with Cisco Unified Client Services Framework if the user
is using Unified Personal Communicator version 8.0 or later.
