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 and SIP-based Interactive Connectivity Establishment (ICE) and Session Traversal Utilities for Network Address Translator (STUN).

The SwitchCenter software  supports traversal between public and private networks.

Adapt to a variety of video communication requirements with the SwitchCenter.
