SwitchCenter Call Control and Firewall Traversal Server

Provides seamless video communication between networks using both H.323 and Session Initiation Protocol (SIP) registrations as well as multiple traversal protocols. The latter include H.323-based H.460, SIP-based Interactive Connectivity Establishment (ICE), and Session Traversal Utilities for Network Address Translator (STUN).

SwitchCenter software supports traversal between public and private networks, and adapts to a variety of video communication requirements.
