Enabling End-to-end IP Visual Communication by Securely Traversing Firewalls and NATs with TANDBERG Expressway

Overview

TANDBERG's Expressway is the right solution for secure firewall and network address translation traversal. While there are a few solutions available, many are expensive, not secure, not available everywhere, restricting of feature sets, not ISP-friendly and not scalable.This paper identifies alternative solutions and compares them to the TANDBERG Expressway solution for firewall traversal.
