Deployment Model Advantages

Integrating Polycom RealPresence infrastructure with a Cisco Video Communications Server

(VCS) environment using DMA SIP peering or H.323 Gatekeeper neighboring capabilities offers

an open and flexible path both for integrations as well as migrations. Companies with new

acquisitions and Service Providers alike can benefit from Polycom’s open approach to unified

communications. DMA can also provide bridge virtualization capabilities for ad-hoc, Virtual

Meeting Room (VMR) environments to ensure a highly available solution with market-leading

scale. DMA’s flexible SIP capabilities allow for the most open architecture on the market and

also can provide simultaneous integration with other systems such as Microsoft Lync.
