Abstract: Techniques are described for elevating calls with a hybrid mixer that combines the functionality of a back-to-back (B2B) mixer and a group call (GC) mixer to enable early media flow during call setup. Upon detecting initiation of a call, a call service determines that elevation of the call to add an additional participant is advised and internally spawns a hybrid B2B/GC mixer. The additional participant is added to the hybrid mixer, and then the caller and callee are sequentially added to the hybrid mixer. The additional participant can be a recording application or another call participant. The hybrid mixer processes intercepted communications sent between the caller and callee throughout the call setup process to maintain their B2B relationship.

Abstract: 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.

Abstract: A device and method for routing an incoming call event to a selected telephony application based on network quality. Upon receiving an incoming call, the device measures the quality of the network connection and compares it to a predetermined threshold. Based on this comparison, the device automatically selects between a default first telephony application and a second telephony application that requires higher network quality. The incoming call is then routed to the selected application, and a communication link is established with capabilities adapted to the measured network quality. The device may continuously monitor network quality and transition between applications if conditions change. Additional features include detecting screen viewability to trigger transitions, associating call continuity identifiers for seamless switching, and adjusting thresholds based on network type.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
