Polycom (RMX) 1500 User Manual

Appendix I-Polycom Open Collaboration Network (POCN)

Polycom, Inc.

Using this topology, both companies connect to a Service Provider via a Cisco Session Border 

Controller (SBC). The Service Provider functions as a B2B Telepresence Exchange, enabling 

multipoint calls between the two companies and their respective video and audio endpoints 

using the MCU as the conference bridge.
The SBC functions as a firewall that the Service Provider can configure according to Trust 

Relationships between two or several companies. By using this method, companies do not 

have to open their corporate firewalls and administer connectivity with the many 

companies they may need to communicate with.
Two topology models are discussed:
•

Model 1: 
—

Company A has a Polycom only environment.

—

Company B has a Cisco only Environment.

•

Model 2: 
—

Company A has a mixed Polycom and Cisco environment.

—

Company B has a Cisco only Environment.
