NAT (Network Address Translation) Traversal

NAT Traversal is a set of techniques enabling participants behind firewalls to connect to

conferences, hosted on the Collaboration Server, remotely using the internet.

Session Border Controller (SBC)

All signaling and media for both SIP and H.323 will be routed through an SBC.

The following SBC environments are supported:

•RealPresence Access Director (RPAD) - a Polycom SBC

•Acme Packet - a 3rd party SBC

•VBP - Polycom Video Border Proxy

Deployment Architectures

The following NAT Traversal topologies are given as examples. Actual deployments will

depend on user requirements and available infrastructure:

Remote Connection Using the Internet

The following Remote Connection call flow options are supported:
