Presence-Enabled Users: Protocol for Controlling Cisco Unified Communications Manager Phones

B.

The CTI gateway provides desk phone control when users are configured for phone association mode.

Proper installation calls upon information to specify CTI gateway server names, addresses, ports, and protocols on CUPS.

Configured correctly, the CTI gateway enables users logging in to CUPC to reach the CTI gateway.

The correct answer is B. CTI/QBE.

Cisco IM and Presence provides presence and instant messaging capabilities, while Cisco Unified Communications Manager is used to manage voice and video calls. In a Cisco Collaboration environment, users can leverage presence information to manage their calls and control their phones through Cisco IM and Presence.

CTI stands for Computer Telephony Integration, which enables communication between the phone system and computer applications. QBE stands for Quick Buffer Encoding, a compression algorithm used for sending large volumes of CTI messages between systems.

Presence-enabled users can control their phones by sending CTI/QBE messages to Cisco Unified Communications Manager through Cisco IM and Presence. For example, a user can use the Cisco Jabber client to change their phone state to 'Do Not Disturb' or forward calls to another number.

Therefore, Option B, CTI/QBE, is the correct protocol used by presence-enabled users in Cisco IM and Presence to control phones registered to Cisco Unified Communications Manager. Option A, AXL/SOAP, is a protocol used for administrative tasks, such as creating, modifying, and deleting Cisco Unified Communications Manager objects. Option C, SIP/SIMPLE, is a protocol used for presence and instant messaging, but not phone control. Option D, LDAP, is a protocol used for directory services. Option E, XMPP, is a protocol used for instant messaging and presence, but not phone control.
