Provides seamless video communication between networks using both H.323 and Session Initiation Protocol (SIP) registrations as well as multiple traversal protocols, including 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.

1. Separated SwitchCenter 

2. If you need to firewall/NAT traversal, you must configure the Separated Switch Center

3. The max number of register to Separated SC is 6000,the max traversal bandwidth of one SC is 300M.

4. The max number of SC managed by SMC2.0 is 50.

5. SC must be used with SMC2.0

6. When used as a firewall traversal server, all devices need to register to the SC, not the embedded GK in SMC2.0
