For those who use video conferencing to conduct business and improve communications, complex dialing strings can be a major roadblock, as they are hard to remember and difficult to use. LifeSize UVC Access simplifies call-dialing policies and enables abbreviated numeric and URI dialing for H.323 endpoints and infrastructure devices.


Controlling utilization of limited network bandwidth is a daily challenge for IT leaders.  LifeSize UVC Access gives IT administrators full command of the video network with zone-specific control over bandwidth usage.


LifeSize UVC Access offers flexible licensing so you can buy the capacity you need today and scale as you grow, thus ensuring improved utilization of IT resources and money. The LifeSize UVC Video Center, along with all the applications on the UVC Platform, are also optimised to run on VMware and Microsoft Hyper-V virtualization technologies.


LifeSize UVC Access is part of the LifeSize® UVC Platform™, which consolidates the capabilities of multiple single-purpose video infrastructure products and makes them instantly accessible from one common interface. Available as virtual machine software or hardware, the UVC Platform enables immediate deployment of LifeSize UVC Access with an easy try-before-you-buy option.
