LifeSize Bridge redefines HD video conferencing for large multiparty calling. Unlike other systems on the market today, LifeSize Bridge scales intelligently with your needs while providing unmatched quality and groundbreaking price/performance for multiparty video communications—with up to 48 participants on a single call in 1080p.

LifeSize Bridge offers a low-risk, cost-effective platform to modularly extend HD video conferencing to more people and with the lowest TCO in the industry.



  • Up to 1080p30 and 720p60
  • Any codec, any speed, any resolution, any layout
  • ISDN connectivity
  • Up to 48 participants
  • Interoperable and standards-based


Interoperable and standards-based, the easy-to-set-up and easy-to-use LifeSize Bridge can be deployed where you need it most. LifeSize Bridge supports any codec, frame rate, call speed or resolution, up to 1080p, without loss of capacity or capability.

To meet the needs of multiparty, collaborative conferencing, LifeSize Bridge is available with 16-port, flat capacity symmetric HD video support. This ensures a consistent, immersive HD quality experience for every user.

Organizations can deploy LifeSize Bridge using scheduled calls, on-demand calls or a hybrid of both, thereby providing maximum flexibility for system administrators. With logical call layouts, data sharing and continuous presence coupled with voice-activated switching, LifeSize Bridge creates a true-to-life conference environment.
