costs. A bridge sends a BPDU frame using the unique MAC address of the port as a source address, and
a destination address of the Spanning Tree Protocol (STP) multicast address 01:80:C2:00:00:00.

CTI Manager is required in a cluster for applications that use TAPI or JTAPI Computer Telephony
Cisco CTI Manager
Integration (CTI). The CTI Manager acts as a broker between the CTI application and the Cisco Unified
Communications Manager Service. It provides authentication of the application and enables control or
monitoring of authorized devices. The CTI application communicates with a primary CTI Manager and,
in the event of a failure, will switch to a backup CTI Manager. The CTI Manager should be enabled
only on call processing subscribers, thus allowing for a maximum of eight CTI Managers in a cluster.
Cisco recommends that you load-balance CTI applications across the various CTI Managers in the
cluster to provide maximum resilience, performance, and redundancy.
Cisco Unified CM. Application that extends enterprise telephony features and capabilities to packet
Cisco Unified
Communications telephony network devices such as IP phones and multimedia applications. Open telephony application
Manager
interfaces make possible services such as multimedia conferencing and interactive multimedia response
systems.
Contraction of coder-decoder. Integrated circuit device that typically uses pulse code modulation to
codec
transform analog signals into a digital bit stream and digital signals back into analog signals.
