For full details on system capacities, refer to Avaya IP Office™ Platform Guidelines: Capacity.

The following table summarizes the overall system capacity for conference calls and maximum participants in any individual conference call. This capacity limits apply to all conference types.

System meet-me conferences use the same resources as above. However, in addition there are limits on the number that can be configured.

In an IP Office Server Edition/Select network, these conferences are hosted on the primary server. If a secondary server is present, that server will host the system conferences during primary server resilience.
