Which of the following UCM services enables the use of Cisco Unified Personal Communicator in desk phone
control mode when integrating a CUPS server with UCM? (Select the best answer.)

A.
Cisco AXL Web Service

B.
Cisco CallManager

C.
Cisco CTIManager

D.
Cisco TFTP

Explanation:
The Cisco CTIManager service enables the use of Cisco Unified Personal Communicator in desk phone control
mode when integrating a Cisco Unified Presence (CUPS) server with Cisco Unified Communications Manager
(UCM). The Cisco Computer Telephony Integration (CTI) feature is a development system that enables
programmers to create applications that can connect to and communicate with a Cisco Unified
Communications system. The CTIManager service is required in order to use Cisco Unified PersonalCommunicator in desk phone control mode. Unified Personal Communicator communicates with the desk
phone by using the CTI Quick Buffer Encoding (CTIQBE) protocol.
The Cisco Trivial File Transfer Protocol (Cisco TFTP) service does not enable the use of Cisco Unified
Personal Communicator in desk phone control mode. However, the Cisco TFTP service enables the use of
Cisco Unified Personal Communicator in softphone mode when integrating a CUPS server with UCM. The
Cisco TFTP service is also used by UCM to update physical IP phone firmware.
The Cisco CallManager service does not enable the use of Cisco Unified Personal Communicator in desk
phone control mode. However, the Cisco CallManager service, which is also called the Cisco Unified
Communications Service, is required for UCM to use software call processing, signaling, and control.
Cisco Administrative Extensible Markup Language (AXL) Web Service does not enable the use of Cisco Unified
Personal Communicator in desk phone control mode. However, the Cisco AXL Web Service is required to
enable the synchronization of data between CUPS and UCM.
