An online meeting system begins the process of connecting a user to an online meeting when a request is received from a user to start or join the online meeting. In response to the request, a pre-meeting user interface (UI) is displayed having a user interface control which, when activated, enables transmission of audio and/or video data for the online meeting, and prior to activation of the control, connection parameters are shared with an online meeting service to preheat the meeting. In response to activation of the control, transmission of audio and/or video data for the online meeting is enabled.

Reducing setup time for online meetings

A method and system for causing a call leg transition based on determining that a screen of a device is not viewable to a user are disclosed, comprising receiving, using a default first telephony application, an incoming call event having a first call leg over a first connection to a telecommunication network addressed to the device, accepting the incoming call event using a second telephony application, creating a second connection having a second call leg to the telecommunication network corresponding to the incoming call event, associating a call event continuity identifier unique to the incoming call event with each of the first and second call legs so that the first and second call legs are connectable at a common port in the telecommunication network, determining if the screen of the device is viewable to the user, and causing a transition from the second call leg to the first call leg based on determining that the screen of the device is not viewable to the user.

Viewable screen based call leg transition

A method and system for triggering hand-off of an incoming call event from a default first telephony application to a second telephony application on a device are disclosed, comprising receiving an incoming call event addressed to the device, causing a notification of the incoming call event using the default first telephony application on the device, during the notification of the incoming call event, and without answering the incoming call event using the default first telephony application, receiving a navigation input on a user interface of the device to navigate to the second telephony application on the device, and, responsive to receiving the input to navigate to the second telephony application on the device, causing the second telephony application to be displayed on the device, and accepting the incoming call event using the second telephony application, creating a telephony connection corresponding to the incoming call event.

Event triggered call transition

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

An online meeting system begins the process of connecting a user to an online meeting when the user enters a prejoin dialog for choosing meeting settings, rather than waiting until the user chooses to actually join the meeting after entering settings. Starting the meeting connection process at this time allows a shorter perceived connection time to the meeting and thus reduces user frustration with the meeting system.

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 an initial hold and a content delivery service, during which the client device placed on the initial hold may place a subsequent hold, resulting in multiple concurrent holds. The communication system allocates a unique identifier to the subsequent hold and updates records associated with the initial and subsequent holds to include an indication that the client device that ends the hold should be placed on hold. The communication system terminates the communication session between the client device placed on the initial hold and the content delivery service and returns the unique identifier allocated to the subsequent hold to the client device that initiated the subsequent hold.

Initiating a subsequent hold

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

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.

Effecting communication events

Voice call continuity is provided for calls that are carried over a hybrid network infrastructure in which access connections are distributed over loosely coupled network portions including a backend network such as a core VoIP (Voice over Internet Protocol) service network, one or more cellular mobile networks, and a public switched telephone network ('PSTN'). The calls are routed through the core VoIP network regardless of their points of origination or termination in other network portions so that signaling and call context are anchored in the core VoIP network. The conditions under which user equipment operate are continuously monitored so that when a connection is determined to have been unacceptably degraded or is likely to be interrupted, and/or a more optimal connection is available, a handover of the call to another connection is initiated so that call continuity is maintained using the lowest cost connection that provides acceptable call quality.
