Abstract: Telephonic and other endpoints often make presence information of other users available on the endpoint. Systems whereby every user sends a notification to every other user quickly becomes resource intensive. Providing presence information only to users subscribed to the presence of other users helps; but, maintaining such subscriptions is often overlooked. Providing automatic subscriptions based upon a triggering event allows presence information to be provided to associated users. The presence information may be time limited to allow for an appropriate amount of presence information to be provided for a duration most likely determined to be relevant. Upon expiration of the subscription, the utilized resources are released without requiring any human intervention.
