    Abstract: Exemplary embodiments relate to techniques for connecting two users when a caller places a call but a callee rejects the call or fails to answer in a predetermined period of time. The calling application may terminate the call attempt and request status updates regarding the called party to determine when the callee is available for a follow-up call. The system may gain insight into when a user is available based on the user's presence in a messaging or social networking app, activity in a third-party application unrelated to the call, or the power status of the user's device. When it is determined that the callee is available, a notification may be sent to the caller informing the caller that it is a good time to call back. The techniques may also be used in reverse, informing the callee of when the caller is available for a return call.

    Abstract: Exemplary embodiments relate to techniques for facilitating a connection between two users in a call by providing an “answering window” when a user calls. When a caller places a call to a callee, the call invitation may remain open for a window of time during which the caller remains available. The callee may opt to answer the call at any time during the window. During the window, the caller may be placed in a lobby and may share audio and/or video. Accepting the call during the answering window may place the callee in the lobby or may directly convert the interaction into an active call. The callee may request that the window can be altered, or may signal their intention to answer the call at a particular time.

    Abstract: In one embodiment, a method includes receiving from a client system associated with a first user a user input based on one or more modalities, at least one of which is a visual modality, identifying one or more subjects associated with the user input based on the visual modality based on one or more machine-learning models, determining one or more attributes associated with the one or more subjects respectively based on the one or more machine-learning models, resolving one or more entities corresponding to the one or more subjects based on the determined one or more attributes, executing one or more tasks associated with the one or more resolved entities, and sending instructions for presenting a communication content including information associated with the executed one or more tasks responsive to user input to the client system associated with the first user.

    Abstract: Exemplary embodiments relate to techniques for displaying participants in an interface during a group call, and is particularly well-suited to use with small displays. A full-size call interface may be shrunk down into a chathead that makes good use of limited screen real estate, especially when being used on a mobile device. On the smaller chathead, the dominant user is shown, and a roster of users is shrunk and may exhibit reduced functionality. The chathead may be moved around the screen, and other applications may continue to run in the space not occupied by the chathead.

    Abstract: Exemplary embodiments relate to techniques for selecting which users should be shown in an interface during a group call, and for presenting the users on (potentially small) displays. According to some embodiments, a most-relevant speaker is selected for display on each call participants' screen. When deciding which user to display in the primary window of a video call, a dominant or relevant user is selected. A dominant user may be selected based on the audio energy represented by the audio packets for the user's device; alternatively dominant user selection may be implemented using artificial intelligence or machine learning, allowing for better differentiation between speaking and noise. On each user's display that does not belong to the relevant user, the current relevant user is shown. On the current relevant user's display, the previous relevant user is shown.
