Abstract: Methods and apparatus are disclosed for notifying one or more users of information. One or more users are identified that have entered a subscription that matches the information; and a communication flow expression is generated that contains at least one primitive keyword indicating how a notification to the identified users should be processed. The communication flow expression may be provided, for example, to a third party for delivery. Typically, a request identifier is received back from the third party and forwarded to the application associated with the information. The communication flow expression comprises at least one recipient for the notification. The identified users may be required to have appropriate privileges associated with the information before being added to the communication flow expression.

Abstract: An event notification system notifies one or more designated persons of an event or emergency that has been reported by an endpoint to a receiver. When a call is received by the receiver, an event notification process identifies the endpoint. One or more designated persons are identified that should be notified when a call is received from this endpoint. The notification message that is generated and optionally the particular designees that are notified can be based on information about the call. The event notification may be triggered by a received call. The designated persons can be notified by an event notification system using a communication flow expression according to the delivery preferences of each designated person. The disclosed event notification system optionally obtains the responses of the designees, and records the status of the notification process.
