SIP Proxy Failover With Polycom® Distributed Media
Application™ (DMA™) 7000
Collaboration Server systems that are part of a RealPresence DMA system environment can benefit from
the RealPresence DMA system's SIP Proxy Failover functionality.
SIP Proxy Failover is supported in the RealPresence DMA system's Local Clustering mode with redundancy
achieved by configuring two DMA servers to share a single virtual IP address.
The virtual IP address is used by the Collaboration Server as the IP address of its SIP Proxy.
No additional configuration is needed on the Collaboration Server.
Should a SIP Proxy failure occur in one of the RealPresence DMA system servers:
● The other RealPresence DMA system server takes over as SIP Proxy.
● Ongoing calls may be disconnected.
● Previously ongoing calls will have to be re-connected using the original IP address, registration and
connection parameters.
● New calls will connect using the original IP address, registration and connection parameters.
