Abstract: Systems and methods for enabling an audio conference are provided. In one aspect, a system includes a transmitting device which receives audio signals representing sounds captured by at least two microphones from participants situated at a first location. A time-of-arrival delay between at least two of the audio signals is calculated and a beam-formed monaural audio signal and corresponding spatial data are generated and transmitted to remote participants situated at a second location. A receiving device processes the beam-formed monaural audio signal based on the spatial data to render and output spatial audio via speakers to the remote participants at the second location. In various aspects, the spatial data may include an angular value or a participant identifier that are determined based on the time-of-arrival delay. The spatial data may also indicate a total number of conference participants that are detected at the first location.

Abstract: A method for shifting an original call established between a first user device (1) and at least a correspondent device (2) through a first application server (3) in order to route it through a second application server (4), the method comprising—instructing the first application server (1) to forward the original call through the second application server (4) to the first user device (1) upon receiving the application server shift instruction, the first application server being instructed to establish a three-way conference communication between the first user device (1), the correspondent device (2) and the second application server (4) in order to forward the original call from the first application server (3) to the second application server (4); —determining that an incoming call routed from the second application server (4) to the first user device (1) has an identification information matches identification information of the original call; —causing the first user device (1) to pick-up the incoming call

Abstract: A method for interfacing a plurality of videoconferencing client devices the method comprising, in a computer server (5) connected to a client devices:—receiving a first client video stream (7) from the video routing client (4);—tagging a video image of the first client video stream received from the video routing client;—sending, through a bidirectional communication channel (14), the first client video stream (21) to a mixing client (2);—receiving, through the bidirectional communication channel with the mixing client, a mixed video stream (15) from said mixing client;—detecting in the mixed video stream received from the mixing client a video image portion which is different from the tagged video image of the first client video stream;—extracting the detected video image portion from the mixed video stream;—generating a second client video stream (23) from the extracted video image portion;—sending the second client video stream to the video routing client.

Abstract: A system for managing interactions within an enterprise includes a network-connected server, and software executing on the server from a non-transitory physical medium, the software providing a first function for establishing a recorded instantiation of a reoccurring event and assigning a unique identifier to that event, a second function for creating an abstract conversation entity object representing the reoccurring event and for creating an executable conversation instance entity object to represent specific meetings or collaboration events under the reoccurring event, a third function for matching any incoming or outgoing interactions or interaction requests that materialize within the enterprise domain to the conversation instance entity tied to the conversation entity, and a fourth function for managing and archiving the interaction records and results thereof as searchable interaction records tied to the conversation instance entity.

Abstract: A device is dedicated to the processing of audio and video data for multimedia communication, via an asynchronous network, between first LAN audio and video terminals and second LAN audio and video terminals. This device includes i) a connector which establishes communications with the first LAN audio and video terminals and with other connectors installed in another device, ii) a first dating module which attaches a transmit time mark and an identifier to the audio and video data emitted by the first LAN audio and video terminals, before their transmission to the other connector and iii) a processor which determines a time difference representing the transmission time difference between the received audio and video data and presenting the same identifier.

Abstract: A method for the synthesis of a user's interactions associated with a user, characterized in that it comprises the following steps: aggregating a user's interactions from interaction means (10, 20, 30, 41, 40) associated with a user; identifying the users concerned by said actions; identifying the interaction means associated with each concerned user; recovering the information received to establish at least one interaction via the identified interaction means; checking the availability of the identified interaction means; caching inside the user's terminal retrieved information related to said identified users' available interaction means; presenting interaction notifications to the user.
