  • Publication number: 20230114797
    Abstract: A video voicemail recording system enables a caller to leave a conventional audio voicemail message over the telephony connection used for routing a call or to leave a message of a different communication modality using a client application at the calling device. A call is routed to a client device from a calling device. In-call options for selection at the calling device are presented responsive to the call going unanswered, in which a first in-call option allows an operator of the calling device to record an audio-only voicemail message over the telephony service and a second in-call option allows the operator of the calling device to record or input a message of a second communication modality (e.g., a video message). A request to open the client application at the calling device is transmitted responsive to a selection of the second in-call option. The message is received in response thereto.

  • Patent number: 11575792
    Abstract: A conference service number system enables the reconfiguration of an existing telephone number as a service number usable for selectively routing calls to each of a client endpoint and a dedicated conference software instance. A conferencing system implements separate conferencing software instances for individual operators for whom unique telephone numbers, are assigned. A telephony system facilitates calls to and from telephone numbers and implements a menu system (e.g. an interactive voice response (IVR) menu) for presenting a caller with options to either route a call to a specific telephone number to the subject operator (e.g., to a client device of that operator) or to a conferencing software instance implemented specifically for that operator. The call is accordingly routed to either a device of the operator or to the conferencing software instance based on the selection by the caller.

  • Publication number: 20230030849
    Abstract: A user experience workflow may be configured based on input received for various object types selectively arranged within the user experience workflow and then bound to a destination identifier, such as a telephone number or web address. A user interface of software for configuring a user experience workflow is presented at a user device and input from that user device is used to selectively arrange objects within a user experience workflow and/or to configure objects thereof. After configurations are applied to the objects, the user experience workflow is bound to the destination identifier. An end user device which accesses the destination identifier (e.g., by calling the telephone number, visiting the web address, or using an application connecting to the web address) may then traverse the user experience workflow, including in some cases having configured content presented thereto.

  • Publication number: 20230034158
    Abstract: Location determination and telephone number distribution for emergency calls is enabled by a telephony system which maintains multiple pools of telephone numbers. Each pool corresponds to a different region such that the pools of telephone numbers are defined at the region-level rather than at the site-level. The telephony system determines the location of a calling device initiating an emergency call regardless of whether the calling device is at a known site. Based on the determined location of the calling device, one of the pools of telephone numbers which corresponds to that location is selected. The telephony system thereafter distributes a telephone number for the calling device to use for the emergency call from that selected pool of telephone numbers to facilitate an emergency call between the calling device and a local public safety answering point.

  • Publication number: 20230032769
    Abstract: A conference participant is alerted as to an event during a conference responsive to a determination that a focus of the conference participant is other than on the conference. During the conference, an event associated with the conference participant is detected based on a real-time transcription of the conference. For example, the event may relate to a topic relevant to the conference participant or a request associated with a name of the conference participant. A determination is made that a focus of the conference participant is other than on the conference based on information associated with a device of the conference participant, such as input received from a camera associated with the device or a setting of an audio output device associated with the device. Based on that determination and the detected event, output is presented to alert the conference participant as to the event.

  • Publication number: 20230035845
    Abstract: Message-based interactive voice response (IVR) menu reconnection is used to reconnect a calling device to a destination at a specific node of a call path after the calling device disconnects from a call with the destination. Menu options of an IVR service presented during a call between the calling device and the destination are determined responsive to the calling device disconnecting from the call. A message including one or more selectable elements each associated with one of the menu options is then transmitted to the calling device. Responsive to a selection of a selectable element at the calling device, the calling device is connected to a destination endpoint. Thus, where the calling device had partially or fully traversed an IVR service during the call, the message-based IVR menu reconnection disclosed herein enables the calling device to reconnect to the destination without having to repeat that IVR service traversal.

  • Publication number: 20220353365
    Abstract: A disconnection of a client device is disconnected during a multi-participant communication, such as a call or a conference. An indication of the disconnection is transmitted to the client device to cause an agent at the client device to record media locally at the client device. The media recorded by the agent at the client device based on the indication of the disconnection is later received and included within a recording of the communication. For example, a gap of the recording in which the disconnection occurred may be identified, such as by performing a comparison of media within the recording to identify a start time of the gap and an end time of the gap. The media is then inserted within a portion of the recording of the multi-participant communication corresponding to the gap.
