Re: DMA: MCU: Insufficient User Connections [3013]

From the DMA Operations Guide:


"Note: MCU connections

In order to efficiently manage multiple calls as quickly as possible, the Polycom RealPresence DMA

system uses multiple connections per MCU. By default, a RealPresence Collaboration Server or RMX

MCU allows up to 20 connections per user. We recommend not reducing this setting (the


RealPresence DMA supercluster with three Conference Manager clusters and a busy conferencing

environment, we recommend increasing this value to 30."
