In one embodiment, an internet telephony apparatus includes a network interface, connectable to a communication network, for sending and receiving internet telephony signals over the communication network. The apparatus further includes a telephone interface, connectable to an analog telephone device, for sending telephone control signals to the telephone device and receiving telephone control signals entered through a keypad of the telephone device. The apparatus further includes a controller operably coupled between the network interface and the telephone interface, the controller implementing a private internet telephony feature server for directing telephone calls, intended for the telephone device, received as internet telephony signals over the network interface and managing telephone services on behalf of the telephone device based on the telephone control signals received from the telephone device over the telephone interface.

A display apparatus includes a communication interface configured to communicate with another display apparatus, a display configured to display contents being shared with the other display apparatus and a video call user interface (UI) for a video call with a user of the other display apparatus, and a processor, in response to at least one of a gesture and a voice of the user included in video call data received from the other display apparatus satisfying a predetermined condition, configured to control the display to change a size of the video call UI displayed on the display.

A communication server and accompanying communication devices allow near instantaneous communication between users of the communication devices. A communication device may be configured with multiple channels, where each channel is assigned a corresponding communication device. As the communication devices are registered with the communication server, each communication device has knowledge of other registered communication devices. Thus, communication devices may communicate nearly instantaneously with each other. Furthermore, as the communication device is equipped with multiple channels, a single communication device may host a conference call with other communication devices. In addition, communication device may include multiple buttons to control the communication device, and indicator lights to indicate the status of calls with other communication devices.

Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining respective video feeds of respective participants of a group of video conference participants, wherein the group of video conference participants includes one or more presenter participant and one or more viewer participant; examining data of the respective video feeds to determine a current group aggregate sentiment output for the video conference, wherein the examining includes subjecting data of feeds of the respective video feeds to sentiment analysis that includes processing of facial feature representing video data of the feeds; and presenting a video conference view to one or more participant of the group of video conference participants based on the group aggregate sentiment output.

Disclosed are techniques for handling emergency calls via an emergency call routing system. A Voice-over Internet Protocol (VoIP) emergency call server may be configured to receive a session initiation protocol (SIP) INVITE for an emergency call from a telephone number serviced by a telecommunication service provider (TSP) SIP call server. The SIP INVITE message header may include multiple location objects including a registered geo-coded address location object associated with the telephone number placing the emergency call, and a location object comprised of lat-long coordinates determined at the time the emergency call is placed. The emergency call server may determine whether the registered geo-coded address and the lat-long coordinates are within a specified distance of one another. When the registered geo-coded address and the lat-long coordinates are within a specified distance of one another, the emergency call server may use the geo-coded address as the location object when handling the emergency call. However, when the registered geo-coded address and the lat-long coordinates are not within a specified distance of one another, the emergency call server may use the lat-long coordinates as the location object when handling the emergency call.

Images of residents of a controlled-environment facility may be captured at the time of intake into the facility. A feature detection process may be performed on each image to verify that corporeal facial features are present in each resident image and a copy of such an image of each resident may be saved. A request to initiate an electronic visitation session may be received and an image of a user is captured. A feature detection process is performed on the captured image to verify that images of features of a corporeal human face are present in the captured image, determining whether an image of a corporeal human face is present in the captured image. The electronic visitation session may then be connected in response to a determination that an image of a corporeal human face is present. Further, a facial recognition process may also be performed on the captured image.

A communication method includes: transmitting a change request from a first conference server to a management server; determining that a second conference server is a conference server after change; transmitting an ID identifying the second conference server from the management server to the first conference server; transmitting a control request from the first conference server to the second conference server based on the ID; performing communication between the second conference server and the management server to confirm whether the second conference server is permitted to control the particular conference room; performing an initialization processing to control the particular conference room; transmitting a completion notification of initialization from the second conference server to the first conference server; transmitting a change instruction from the first conference server to each particular client; connecting each particular client with the second conference server; and disconnecting connection between each particular client and the first conference server.

Systems and methods for providing video subtitling and text communications (e.g., real time text (RTT) and conventional text messaging) during video calls. The system can include video calling with voice recognition based subtitles. The system can also include a call log to provide a textual record of the audio portion of the video call. The system can utilize embedded or online (e.g., cloud-based) voice recognition systems to provide the subtitles and call log. The system can enable users to send RTT, standard text, or other messages to multiple users participating in a video call via a public text interface. The system can also enable users to send private RTT, standard text, or other messages to specified participants during video calls using parallel interfaces.

Methods and systems are described for storing video content collected by a home automation system. According to at least one embodiment, an apparatus for accessing video content collected by a home automation system includes a processor, a memory in electronic communication with the processor, and instructions stored in the memory which are executable by a processor to receive at a remote device live video content from a camera of the home automation system, and initiate real-time, two-way audio communication between the remote device and a user of the home automation system via the camera.
