Secure Firewall Traversal

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. The result is secure, simple to use video communications.

Connect Anywhere, Securely
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.

With LifeSize Transit, experience better communications without compromising on security. LifeSize offers an enterprise-class firewall / NAT traversal solution that will be seamless to end users and simple to set up and manage. LifeSize Transit creates a secure path through a firewall without compromising IP security.

To support more security-conscious environments, LifeSize Transit also allows users to enable TCP communications instead of UDP, and, in a future release will support HTTP communications. This feature allows users to close down selected open port types to gain maximum flexibility and security in their traversal implementation.

Simple to Use
LifeSize firewall traversal technology makes it easy for LifeSize® Room™ to communicate across a firewall to another LifeSize system or other vendor system.

LifeSize Transit includes a SIP-based plug and play appliance that bridges any firewall or NAT boundary including strict corporate firewalls. The LifeSize Transit solution will also work with most common SIP-based endpoints.

High Performance, Scalable
LifeSize Transit Server is scalable and supports up to 20 simultaneous calls up to 1Mbps. Clustering support is available to both increase capacity and increase system resiliency. LifeSize Transit Client will support up to 10 simultaneous calls up to 1Mbps.

Components
