International Classification:

H04M 156

US Classification:

37914217, 37914201, 37914204, 455566

Abstract:

An interactive user interface displayed on a monitor as part of a telephone is disclosed. The interactive user interface allows a user to easily use basic and advanced telephony functions, telephony-related services, such as accessing phone directories and voice mail, and non-telephony services. These non-telephony services can include any information deliverable over, for example, TCP/IP or DHCP, and can include information such as stock prices, weather, sports data, and so on, typically from third-party services. It can also include intra-company information such as meeting schedules, conference room bookings, cafeteria menus, and so on. A user can also pull up context-sensitive âhelpâ information on the display at any time to learn more about a particular mode, option, or feature.

Abstract:

Various aspects of an interactive multimedia system and associated methods. In general, the multimedia system employs central and peripheral hubs that function to provide services to a plurality of clients of a call manager server, or manager subsystem. The hubs and subsystem cooperate to serve requests originating in the plurality of clients. The client-server-client architecture allows for distributed processing and resource management. Redundant connections between the various network subsystems and hubs provide survivability. Each subsystem or hub is provided with the ability to initialize or recover from systemic errors, thereby distributing initialization and recovery. Certain of the distributed resources are capable of being managed from other subsystems, thereby allowing sharing of the resources. An open numbering plan allows efficient call treatment of dialed numbers. Call processing is sharable between multiple manager subsystems.

Abstract:

Methods for concealing audible distortions resulting from changes in jitter buffer size include receiving an audio stream, storing the audio stream in a jitter buffer, and determining a pitch period associated with the audio stream. To expand the jitter buffer, a method includes inserting additional audio data that has a duration corresponding to an integer multiple of the pitch period into the audio stream. To contract the jitter buffer, a method includes removing a portion of the audio stream having a duration corresponding to an integer multiple of the pitch period.

US Classification:

379 9301, 37914217, 37943306, 455566

Abstract:

According to the present invention, methods, data structures, and computer-readable media for processing input to a telephone having an interactive user interlace are disclosed. A telephone user inputs commands through buttons and keys on an interactive user interface. A selection made from a menu on the telephone is detected. The menu can be a collection of options, features or commands corresponding to physical context-sensitive soft keys or a line keys. A message based on the menu selection is created and passed to a menu processing object. If a soft key is pressed, the menu processing object is a soft key processing object. An event based on the menu selection is also created. It is then determined which mode from the numerous modes available on the phone is presently active or has focus. Once the active mode that presently has focus is determined, an appropriate menu label set and segment display is displayed on the display monitor.
