To configure Exchange Collector on Presence Services deployed in Geographic Redundant mode, Exchange Collector must be configured on Avaya Breeze® platform clusters in both data centers. See Configuring Exchange Collector to configure Exchange Collector on each cluster.

During normal operations, a user enabled for presence collection through Exchange Collector is managed by the home data center as configured in Presence Profile. When the data center is not operational, the remote data center automatically takes over the collection of presence information of the user.
