Techniques for determining a global state for multiple related calls are disclosed. A first call between a first device and a second device is established, where the first call is assigned a user call identifier. A second call between the first device and a third device is established. A shared call operation is established by assigning the user call identifier to the second call. The user call identifier is assigned to the second call in addition to already being assigned to the first call. A first status of the first call and a second status of the second call are determined. The first status and the second status are used to determine a global state of the shared call operation. The global state of the shared call operation is updated in response to one or both of the first status or the second status changing.

Shared call state for related calls

Handling a related call using a shared call state. The computing system establishes a first call between a first entity and a second entity, assigns a user call identifier to the first call. Next, the second entity instructs that a second call between the first entity and a third entity is to be established. The computing system then establishes the second call between the first entity and the third entity, assigns the same user identifier to the second call, such that the first call and the second call are included in a shared call operation. A first global state of the shared call operation is identified based on a status of at least one of the first call and the second call. When the status of at least one of the first call and the second call changes, the global state of the shared call operation changes from the first global state to a second global state.

Disclosed are systems, methods, and non-transitory computer-readable media for delivering content to a client device placed on hold. A communication system establishes a communication session between a client device placed on hold and a content delivery service, during which the content delivery service streams content to the client device via the established communication session. The communication session between the client device that initiated the hold and the client devices that are placed on hold is terminated, thereby allowing the client device that initiated the hold to establish communication sessions other client devices if so desired. A unique identifier generated to reference the hold is provided to the client device that initiated the hold, which the client device may then use to reference the hold to execute a desired action, such as ending the hold, terminating the communication session, retrieving a status of the hold, etc.

Delivering content during a hold

Techniques for controlling reactivation of service functions are described. Implementations, for example, enable various ways of controlling and storing service objects that provide service functions.

Reactivation of service objects using call back address for a communication event

An online conferencing system that provides an automatic mechanism to broadcast an online conference. A video gathering component gathers video streams for each of at least some of the current participants in the online conference. A broadcast start triggering component allows one or more of the participants to trigger operation of a broadcasting component. The broadcast component that, when triggered, causes a resulting video stream comprising at least a composite of at least some of the gathered video streams to be published to a plurality of viewers. In some embodiments, pre-processing of the video streams to create the resulting video stream also occurs. Such pre-processing could include, for instance, composing a stream from multiple video streams, altering one or more of the video streams, applying augmented reality to the video stream, and so forth.

Online conference broadcast using broadcast component

A service is delivered by a computer system comprising a processor, a memory accessible to the processor and computer storage. The memory holds code which defines service object classes. The service object classes are configured to provide service functions, and the service object classes are instantiated to create service objects which implement the service functions. For each service object, an associated service object identifier is generated in the memory which distinguishes that service object from any other service object. The service objects are serialized to generate serialized data, the serialized data comprising a representation of each service object, and the representation comprising that service object's service object identifier, that service object's associated state data and the service object identifier of any other service object referenced by that service object. Following deactivation, the service objects can be recreated by following the chain of references.

Controlling service functions in response to service instigation and service reactivation messages

Disclosed are methods and devices (e.g. servers) for establishing a real-time communication event between a user of a client device and another user of another client device via a communication network. A message pertaining to the communication event (e.g. to a communication event establishment procedure) includes multiple options pertaining to the communication event and, for each of the multiple options, a different network address unique to that option which can be accessed to select that option.
