Abstract: A registration is received from an application framework. The registration is for the application framework to be notified of an event managed by a service gateway. The event is based on a communication service provided by the service gateway. The service gateway detects the event. The service gateway sends a notification associated with the event to the application framework. The notification associated with the event comprises information associated with the event. For example, the notification may include a caller's name and address. An object is received from the application framework that is associated with the event. The object associated with the event further comprises extension information that is not used by the communication service/service gateway. A message is sent to a communication endpoint and/or an external application that comprises the object. The extension information is used to provide custom services that are not supported by the communication service/service gateway.

Abstract: Methods and systems are provided for automatically determining whether participant devices in a collaborative communication session are synchronized with content shared by a presenting device. The methods and systems present an indication to a presenting device regarding a status of each participant device. The indication may include an interactive display configured to render an image, or images, representing the content one or more participant devices have received according to a state of synchronization of the participant devices in the communication session.
