How cisco telepresence works
Cisco TelePresence creates a virtual, in-person user experience using advanced visual, audio, and interactive technologies over an IP network.
Meetings that formerly took place by conference call can now include life-sized participants projected on screen with the ability to interact in real time from locations worldwide.
