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

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

A communication event is established between an initiating device and a responding device under the control of a remote communications controller. In a pre-session establishment phase: a compression dictionary or a dictionary link that identifies an addressable memory location, at which a compression dictionary is held, is received at the initiating device. The received compression dictionary or the received dictionary link is stored in electronic storage of the initiating device. In response to a communication event establishment instruction received at the initiating device after the dictionary or the dictionary link has been received and stored at the initiating device, a session is established between the initiating device and the communications controller by the initiating device transmitting an initial session establishment message&#x2014;compressed using the dictionary&#x2014;to the communications controller to establish the communication event.

Data compression for communications signalling

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 communication event is established between an initiating device and a responding device under the control of a remote communications controller. In a pre-communication event establishment phase, a secure connection is established between the initiating device and the communications controller, and session key negotiation messages are exchanged between the initiating device and the communications controller via the secure connection to obtain session key data in an electronic storage location accessible to the initiating device. The secure connection terminates once the session key data has been obtained. In a subsequent communication event establishment phase&#x2014;after the session key data has been obtained and the secure connection has terminated in the pre-establishment phase&#x2014;a communication event request is transmitted from the initiating device to the communications controller comprising a payload encrypted with the session key data.

Establishing a communication event using secure signaling

Establishing a communication event using secure signalling

A session is established between an initiating device and a remote device. A session request is transmitted from the initiating device to the remote device according to a preferred networking protocol. If no provisional response to the request is received at the initiating device within an initial duration, the initiating device transmits another session request to the other device according to a non-preferred protocol. If a provisional response to the request is received within the initial duration, the initiating device continues to monitor the elapsed time for an so extended duration. If no final response to the request is received within the extended duration, the initiating device transmits another session request to the other device according to a non-preferred protocol. If a final response is received within the extended duration, a session between the initiating device and the other device is established according to the preferred networking protocol.

Protocol fallback

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.
