Chapter 2: Polycom Unified
Communications with Cisco
Interoperability
This chapter provides an overview of the features offered in the various Cisco environments
where Polycom® Unified Communications (UC) products can be integrated.
The Polycom video infrastructure allows you to integrate with Cisco Unified Communications
Manager (CUCM) or Cisco Video Communications Server (VCS) infrastructure to enable
common dial plans between Polycom and Cisco Unified IP phones or video endpoints.
Supported Deployment Models
Polycom supports the following deployment models when integrating Polycom Unified
Communications with Cisco environments:
• Direct Registration of Polycom RealPresence Systems with CUCM
• Polycom RealPresence Platform SIP Integration with CUCM
• Polycom RealPresence Platform Integration with VCS
• Polycom CMA H323 Integration with CUCM
Direct Registration of Polycom RealPresence Systems with CUCM
When you SIP register your Polycom telepresence endpoints directly with CUCM, you have a
single source for call admission control and bandwidth management. Cisco endpoints can also
use telephony functions like hold, transfer and so on when on calls with Polycom endpoints.
When Polycom telepresence endpoints have the TIP option key installed, they can participate in
calls with Cisco CTS endpoints and Cisco Multipoint Control Units (MCUs) that are TIP-capable.
CUCM can also have direct SIP integration with a Polycom RMX. The RMX system inherently
supports hosting TIP conference calls and can be licensed to handle Immersive Telepresence
multipoint conferences.
For deployment details, see Direct Registration of Polycom RealPresence Systems with CUCM.
Polycom RealPresence Platform SIP Integration with CUCM
You can configure the Polycom® Distributed Media Application™ (DMA™) system as a SIP
proxy and registrar for your video environment. When you use the DMA system as a SIP peer
to CUCM, it can provide a Virtual Meeting Room (VMR) audio and video solution between Cisco
endpoints that are registered with CUCM and Polycom SIP and H.323 endpoints that are
