Chapter 4: Polycom RealPresence
Platform SIP Integration with CUCM
You can configure the Polycom® Distributed Media Application™ (DMA™) system as a SIP
peer and registrar for your environment.
When you incorporate a Polycom DMA system as a SIP peer within your Cisco environment,
you can do the following:
• Use the Polycom DMA system to manage and virtualize conferences on your Polycom
RMX systems.
• Route outgoing calls from the DMA system to the Cisco Unified Communications Manager
(CUCM).
• Route incoming calls from CUCM to endpoints and systems registered to the DMA
system.
See the Polycom DMA 7000 System Operations Guide for more information about using the
Polycom DMA system.
This chapter includes the following sections:

Deployment Model Advantages
Integrating Polycom RealPresence infrastructure with a Cisco Unified Communications Manager
(CUCM) environment using DMA SIP peering capabilities offers an open and flexible integration
that combines the strength of a Polycom RealPresence solution with the advantages of CUCM
telephony. A Polycom RealPresence solution can provide video conferencing services to a wide
variety of CUCM endpoints including multiscreen Cisco CTS systems using TIP for immersive
telepresence conferences. In addition, DMA can also provide bridge virtualization capabilities to
ensure a highly available solution with market-leading scale. DMA’s flexible SIP capabilities
allow for the most open architecture and also can provide simultaneous integration with other
systems such as Microsoft Lync.
