You are integrating an existing Cisco UCM system with a new CUPS server. You will be using Cisco Unified
Personal Communicator in both its softphone mode and its desk phone control mode. You navigate to Cisco
Unified Serviceability > Tools > Service Activation and ensure that TFTP and the Cisco AXL Web Service are
both enabled.Which of the following services must also be enabled on the UCM system to complete the integration?

A.
Cisco CTIManager

B.
Cisco DirSync

C.
Cisco Extension Mobility

D.
Cisco Messaging Interface

Explanation:
The Cisco CTIManager server must also be enabled to integrate an existing Cisco Unified Communications
Manager (UCM) system with a Cisco Unified Presence (CUPS) server and to use Cisco Unified Personal
Communicator in both its softphone mode and its desk phone control mode. 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. By using CTI, programmers can
create server software and desktop applications that interface directly with UCM, CUPS, and other Cisco Voice
over IP (VoIP) products. In order to use Cisco Unified Personal Communicator in desk phone control mode, the
Cisco CTIManager service must be enabled and started on UCM. Unified Personal Communicator
communicates with the desk phone by using the CTI Quick Buffer Encoding (CTIQBE) protocol.
Cisco CallManager, Cisco Trivial File Transfer Protocol (Cisco TFTP), and Cisco Administrative Extensible
Markup Language (AXL) Web Service must also be enabled and started in order to integrate CUPS and UCM
in the configuration described in this scenario. The Cisco TFTP service is required to enable Cisco Unified
Personal Communicator to operate in softphone mode. The Cisco AXL Web Service is required to enable the
synchronization of data between CUPS and UCM. Finally, the CallManager service, which is also called the
Cisco Unified Communications Service, is required for UCM to use software call processing, signaling, and
control.
The Cisco Directory Synchronization (DirSync) service is not required to integrate CUPS with UCM. The Cisco
DirSync service enables an administrator to keep the UCM database synchronized with external directories,
such as Microsoft Active Directory.
The Cisco Extension Mobility service is not required to integrate CUPS with UCM. Extension Mobility enables a
user to log in to an IP phone that is capable of extension mobility service and to use that IP phone with the
same features and settings as the user’s typical desk phone.
The Cisco Messaging Interface service is not required to integrate CUPS with UCM. Messaging Interface
enables the connection of Simplified Message Desk Interface (SMDI) voice mail systems to UCM. The SMDI
protocol defines how voice mail systems interact with telephone systems.
