Company To Company Models Using A Service Provider; Model - Polycom 1500 Administrator's Manual

RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator's Guide

Company to Company Models Using a Service Provider

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 Collaboration Server 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.
