RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide
I-2 Polycom, Inc.
Conferences hosted on the Collaboration Server can include a mix of existing end points
(that do not support TIP) and CTS endpoints.
TIP-enabled endpoints must support TIP Version 7 or higher. Calls from endpoints
supporting older versions of TIP will be rejected.
Deployment Architectures
The following multipoint topologies are given as examples. Actual deployments will
depend on user requirements and available infrastructure:
• Single company with Polycom and Cisco Infrastructure
— CTS and Polycom Telepresence Rooms in a corporate environment.
• Company to company via Service Provider
— Model 1: Mixed Polycom and Cisco infrastructure at one of the companies, Cisco
only infrastructure at the other.
— Model 2: Polycom only infrastructure at one of the companies, Cisco only
infrastructure at the other.
Single Company Model - Polycom and Cisco Infrastructure
The deployment architecture in Figure I-1 shows a company that has a mixture of Polycom
and Cisco endpoints, room systems and telephony equipment that needs to enable
multipoint calls between all its video and audio endpoints using the Collaboration Server as
the conference bridge.
As show in Figure I-1, prior to Version 8.1.1, Cisco Telepresence endpoints could connect to
conferences using the TIP protocol, Polycom endpoints connected to the same conferences
using SIP protocol.
