With the advent of IP communications, connecting to customers, suppliers, partners and colleagues around the globe became easier and more cost effective. Conducting video calls by passing through a network firewall meant opening and closing communication ports, leaving networks vulnerable to possible attacks.

LifeSize® Transit™ is a complete firewall and NAT traversal solution that enables people to make video calls within and across enterprises and organizations by securely traversing firewalls. With standards-based H.460 and SIP tunneling, the result is secure, simple to use video communications.

The Advantages are Clear

The LifeSize Transit solution is composed of the Server and Client appliances, and the Client virtual machine software.


Secure. High Performance. Scalable.

LifeSize Transit Server

The LifeSize Transit Server is scalable and supports up to 20 simultaneous Full HD 1080p calls up to 1.7Mbps. Clustering support is available to both increase capacity and increase system resiliency. The LifeSize Transit Server also provides signaling, media, registrar and gatekeeper services in a single appliance, handling up to 500 device registrations.


LifeSize Transit Client

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


LifeSize Transit™ Client virtual machine

A virtual appliance that can be deployed in a virtualization infrastructure to work along with LifeSize® Transit™ Server appliance. Organizations with existing VMWare server environments will save space, streamline operation, and increase utilization by deploying the virtual machine software option of Transit Client.
