Cisco Systems Inc. rolled out its real-time videoconference system for 50,000 employees worldwide in January, inviting them to test equipment with far-flung friends, family and co-workers.

Most big Cisco offices have TelePresence, which debuted in October. The technology — which includes high-definition monitors, highly sensitive audio equipment and integrated networking gear — starts at $99,000. A system that accommodates at least a dozen people costs $299,000.
