LifeSize® UVC Transit™ is a complete firewall and NAT traversal solution that enables secure Full HD (1080p30) video calls within and across networks. With standards-based H.460 and SIP firewall/NAT traversal, you can talk to colleagues, partners and suppliers reliably and securely. The LifeSize UVC Transit solution, available on the LifeSize UVC Platform, includes the UVC Transit Server and the UVC Transit Client. Together, they make IP video more secure, more reliable and easier to manage.

  • Enables secure intercompany calling
  • Fewer open ports needed for SIP/H.323 traversal
  • Works with LifeSize & 3rd party video systems
  • Deploy within minutes on UVC Platform
  • Integration with existing gatekeeper/SIP PBX


 LifeSize® UVC Transit™ Server

The LifeSize UVC Transit Server provides firewall and NAT traversal for LifeSize and other third-party devices. A single Transit Server at headquarters can connect to multiple LifeSize Transit Clients at regional offices, providing secure intercompany calling.

LifeSize® UVC Transit™ Client

The LifeSize UVC Transit Client preserves network topology, allowing all endpoints and network infrastructure devices to be within the private network. Working as a proxy for the LifeSize UVC Transit Server and residing inside the LAN, it renders firewall/NAT traversal services to all video conferencing devices, including legacy endpoints and servers.

Ultimate Control and Flexibility

LifeSize UVC Transit 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 dollars.

LifeSize UVC Platform

LifeSize UVC Transit 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 UVC Transit Server or UVC Transit Client, with an easy try-before-you-buy option.
