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.
