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

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:

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

Windows in a room allow transmission of extraneous noise light and temperaturenoise, light, and temperature

Windows also create exaggerated sound reverberation within a room

Add i d t t t l f t f Address windows to prevent external factors from permeating into the TelePresence environment and to control sound reflection inside the room

Cisco TelePresence Room RequirementsLighting RequirementLighting Requirement

Proper lighting is critical to the experience!

300-400 lux of well dispersed, horizontal, ambient light throughout the room. 4100k fluorescent bulbs with indirect fixtures; P id 4100k l t t li htProvide 4100k color temperature light source

Minimum illumination of 250 lux is acceptable if the room is not too deep and light cove helps to light up the face;

The lighting in the room should be well controlled. It means block natural sun light or gother type of office light through glass or thin blinds

Lighting source shouldn’t create any
