Explanation:
Cisco Unified Communications Manager (CM) and Cisco TelePresence Video Communication Server (VCS)
are used for call control. Call control devices perform endpoint registration, call routing, call maintenance, and
call monitoring. Cisco Unified CM supports Session Initiation Protocol (SIP), whereas Cisco VCS supports
H.323 and SIP.
Cisco TelePresence Content Server (TCS) and Cisco TelePresence Recording Server (CTRS) are not used for
call control. Cisco TCS is an appliance or blade that provides live recording, streaming, and playback of video
content for any TelePresence or Unified CM endpoint. CTRS is a server that provides recording and playbackof video content for certain endpoints.
Cisco TelePresence Server is not used for call control; it is used as a conferencing device. Cisco conferencing
devices support either switching or transcoding. Switching simply forwards the audio and video to endpoints,
whereas transcoding encodes and decodes the media streams. Cisco TelePresence Multipoint Switch supports
switching; Cisco TelePresence Server, Cisco TelePresence multipoint control unit (MCU) 4000, Cisco
TelePresence MSE 8000, and Cisco Integrated Services Router (ISR) G2 support transcoding.
Cisco TelePresence Manager is not used for call control; it is used as a management device. Management
devices are typically responsible for scheduling, monitoring, and provisioning. Cisco TelePresence Manager is
a server-based platform, whereas Cisco TelePresence Management Suite (TMS) can be delivered as a serverbased software application or as an appliance. Both Cisco TMS and Cisco TelePresence Manager can
interface with Microsoft Exchange. However, Cisco TMS also has a built-in web-scheduling interface; Cisco
TelePresence Manager does not.Cisco: Video Infrastructure Components
