When the Presence Services snap-in is restarted or a cluster High Availability event occurs, the system might take up to an hour for some connected endpoints to receive presence updates. You can reestablish the existing subscriptions. For over-engineered or lightly-loaded Presence deployments, you can shorten this recovery time by shortening the subscription time.
On the System Manager web console, navigate to ElementsAvaya Breeze®Configuration.
Click Attributes.
On the Service Clusters tab, in the Cluster field, click the Presence Services cluster.
In the Service field, click the Presence Services service.
On the Attributes Configuration page, navigate to the System group.
In the Subscription/Publication Expiry Time field, in Effective Value, type the subscription time in seconds.
ADDITIONAL INFORMATION:
Valid values are 600 seconds through 43200 seconds.
The default value is 2000 seconds. For presence deployments with more than 5000 users per server, leave the Subscription/Publication Expiry Time attribute at the default value of 2000 seconds.
To override the default value, select the Override Default check box.
