Which protocol is used by presence-enabled users in Cisco IM and Presence to control phones that
are registered to Cisco Unified Communications Manager?
A.
AXL/SOAP
B.
CTI/QBE
C.
SIP/SIMPLE
D.
LDAP
E.
XMPP
Explanation:
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 Computer Telephony Integration Quick Buffer Encoding (CTI-QBE) connection between Cisco
IM and Presence and Unified CM is the protocol used by presence-enabled users in Cisco IM and
Presence to control their associated phones registered to Unified CM. This CTI communication
occurs when Cisco Jabber is using Desk Phone mode to do Click to Call or when Microsoft Office
Communicator is doing Click to Call through Microsoft Live Communications Server 2005 or
Office Communications Server 2007 or Microsoft Lync
