Abstract:
Systems and methods of selecting a media path for data packets bearing the media of a telephone call to traverse during a voice over Internet protocol telephone call include testing the call quality of multiple potential media paths immediately before a call is setup. The potential media path with the highest call quality is used as the initial media path for the call. If the call quality of the media path currently in use declines below a threshold value during a call, potential alternate media paths are identified and tested for call quality. If one of the alternate media paths has better call quality than the media path presently in use, the call is switched to the alternate media path with the highest call quality.
Abstract:
Systems and methods for conducting a virtual meeting cause a display screen to present meeting participants with a depiction of a virtual meeting room populated with avatars representing the participants. Audio links between the participants allow some or all of the participants to hear what is being said by each of the other participants. Each participant can cause his respective avatar to make gestures that provide non-verbal communications to the other participants. In addition, one or more participants may be able to cause text, images, videos or other presentation materials to be displayed to the other participants on a virtual display screen present in the virtual conference room. Likewise, participants may be able to draw or write on a virtual whiteboard present in the virtual conference room. Participants may also be able to share or send notes to each other, or conduct private instant messaging sessions, audio sessions or video sessions with one or more of the other participants.
Abstract:
A system and method for synchronizing the presentation of a video program on multiple display devices makes use of a synchronized content distribution unit that receives a video program from a content provider as well as text, audio and/or video feeds from at least one user. The video program and the text, audio and/or video feeds are combined, and the combined program is then distributed to the display screens. Synchronization information may be encoded in the combined program, and this information may be used by the display screens or video controller associated with the display screens to cause the combined video program to be displayed on all the display screens in a synchronized fashion.
Abstract:
Systems and methods of recommending that two people form a link on a social networking system use activities conducted by the two people on a telephony system to determine if the two people are likely acquainted. If it appears that both parties are calling each other, or if both parties are placing or receiving calls from common individuals, a recommendation that they form a link on the social networking system is issued to one or both parties.
Abstract:
A method for packet telephony includes receiving over a packet communication network (22) a first message originating from a first end-user (32A) in a first aggregating organization (28) to place a call to a second end-user (32D) in a second aggregating organization (30). Responsively to the first message, respective values are assigned to one or more security attributes that are indicative of a likelihood that the call is a spam call. A second message is transmitted over the packet communication network toward the second end-user, the second message containing at least one of the respective values that was assigned to at least one of the security attributes.
Abstract:
A method and system for a server side detection of a Network Address Translation (NAT) device is provided. During the server-side NAT determination process, the client device is not required to have knowledge of the type of NAT device that the client device is behind. The server side NAT determination process may include comparing between the address information that is embedded by the client device and address information as obtained by units within the server-side NAT detection device.
Abstract:
A method for telephony includes receiving at a facility of a telephone service provider a first subscriber request to place a first call to a specified telephone number. A provider request is sent to a remote server (26), which maintains a database (28) of records associating telephone numbers with respective packet network addresses, for a record (72) indicating a packet network address to which calls to the specified telephone number should be placed. Upon receiving the record from the remote server, the record is stored in a local cache (42) at the facility of the telephone service provider. After storing the record, upon receiving at the facility of the telephone service provider a second subscriber request to place a second call to the specified telephone number, the record is read from the local cache and is used in placing the second call to the packet network address.
Abstract:
IP telephony communications are conducted by sending both data produced by a CODEC that represents received spoken audio input, and a textual representation of the spoken audio input. A receiving device utilizes the textual representation of the spoken audio input to help recreate the spoken audio input when a portion of the CODEC data is missing. The textual representation can be generated by a speech-to-text function. Alternatively, the textual representation can be a notation of extracted phonemes.
Abstract:
A method for call handling comprising receiving, from a first device, an incoming call request directed to a second device, wherein the call request contains call handling information and transmitting an outgoing call request to the second device, wherein the outgoing call request is based at least in part upon the call handling information.
Abstract:
Systems and methods of preventing an Internet service provider from identifying a stream of data packets as carrying a voice over Internet protocol telephony communication can make use of encryption techniques to prevent the Internet service provider from examining the content of the data packets. Also, multiple communications channels may be established between a telephony device and elements of an IP telephony system. A stream of data packets bearing the media of an IP telephony communication is then separated into sub-streams, and each sub-stream is sent through a different one of the communications channels. This prevents an Internet service provider from identifying a stream of data packets as bearing the media of an IP telephony communication based on a pattern in the data traffic.
