Does it really feel like you’re “there” in the room? Can it truly replace a face-to-face meeting? Is each participant adequately seen and heard?

Is each participant adequately seen and heard? Is it utilized heavily, or does it just sit in the corner?

Why TelePresence? Cisco TelePresenceDesign Principles
Cisco Built from the Ground Up!
More than 60% of communication is non-verbal
Experience the meeting, not the technology
Life size high definition
It’s all about the Experience

Existing collaborative technologies don’t adequately replace a face-to-face meeting

Interoperability Facts
G.711 audioCUVC participants hear all the TelePresence participants mixed together in G.711
Likewise the TelePresence participants will hear the CUVCLikewise, the TelePresence participants will hear the CUVC participants mixed together in G.711, coming from the left speaker
No H.239 application sharing between CTMS and CUVCRecommend using MeetingPlace or WebEx to facilitate collaboration
No Far End Camera Control (FECC) for TelePresence participants

Cisco TelePresenceCUCM Cluster Requirements and RecommendationsCUCM Cluster Requirements and Recommendations
Cisco TelePresence requires CUCM version 6.0 or laterRequirements:
Cisco TelePresence has unique bandwidth and QoS requirements—but CUCM cannot differentiate between a TelePresence call and a regular Video Telephony call (to CUCM they’re both “video calls”)
All CTS t t b i t d t th CUCM All CTS systems must be registered to the same CUCM cluster because CTS-Manager can only integrate with a single CUCM cluster
Conditions:
Yes CUCM 6.0 or later?
Recommendation:
Use existing CUCM cluster

Audio Add-In feature: access to the rest of your IP PhonesAudio Add In feature: access to the rest of your IP Phones, MeetingPlace, or the PSTN is required. Either deploy a voice gateway or trunk to your existing CUCM cluster
Future B2B connectivity will require CTS dial plan to beFuture B2B connectivity will require CTS dial plan to be externally reachable
