Abstract: A method of providing cost information associated with one or more contact numbers in an address book may include receiving cost information, storing the cost information, mapping at least a portion of the cost information to one or more contact numbers using one or more pre-defined rules and transmitting the mapped cost information to a mobile device.

Abstract: In an embodiment, a method of accessing contact information on a mobile device may include caching contact information prior to powering off a mobile device, storing the cached contact information on the mobile device and displaying the cached contact information on a display screen of the mobile device when a subscriber accesses the address book after the mobile device is powered on.

Abstract: Systems and methods are presented for enabling improved communication between one or more communication devices such as mobile wireless devices. The present disclosure provides updatable dynamic, or active, phone book capabilities that provide a user with both contact information as well as dynamic network (web) content that can be updated by communication between a mobile device and a server. The disclosure further provides methods and systems for presence-based message delivery based on a criteria such as presence or identity of a caller or caller's device.

Abstract: This invention discloses a system for transmission of audio content to a telephone, the system including an audio stream navigation functionality operable by using a telephone user interface and enabling a user to select audio data to be heard by the user via said telephone, an interactive voice response unit operative in response to an input from said telephone user interface operating said audio stream navigation functionality and a transcoder operative in response to an input from said interactive voice response unit for providing audio data, from an audio source remote from said transcoder, to said interactive voice response unit for listening by said user via said telephone. A method for transmission of audio content to a telephone is also disclosed.

Abstract: The present disclosure generally relates to systems and methods for establishing and maintaining communication between two or more communication devices coupled to communication networks. Some specific aspects relate to communication between a plurality of communication devices each of which is coupled to a respective network. Other aspects relate to establishing such communication by way of contact lists maintained and facilitated on systems coupled to the networks. Users of multiple communication networks, such as VoIP, PSTN and wireless, employ multiple communication devices to communicate with their contacts. For example, a VoIP enabled computer is necessary to access contacts on a VoIP network and a mobile or cellular telephone is used to access contacts on wireless and PSTN networks. A contact list, stored on one communication device, in some instances, cannot be accessed from another communication device.

Abstract: Apparatus and a method for communicating media over a network including encoding the media into a server database at a server, downloading from the server database to a client database generally only those portions of the media which are necessary to satisfy user requests and in response to a user request for a given item of media, determining whether the media is present in the client database, and if not, automatically downloading those portions of the media which are necessary to supply the user with the given item of media from the server database.

Abstract: A method for billing a subscriber to a cellular telephone service for a VoIP call made by the subscriber, the method including determining when a subscriber to a cellular telephone service places a telephone call to a remote device using a local device associated with the subscription, where the telephone call has at least one VoIP call leg, capturing session information related to the telephone call, including information identifying the subscriber, and providing the information to a provider of the cellular telephone service, thereby enabling the cellular telephone service provider to bill the subscriber for the VoIP call.

Abstract: A method and system for automatic conversion of text to speech including automatically analyzing a text to define at least one vocabulary domain and carrying out a text-to-speech conversion by employing said at least one vocabulary domain.

Abstract: A method and system for automnatic conversion of text to speech including automatically analyzing a text to define at least one vocabulary domain and carrying out a text-to-specch conversion by employing said at least one vocabulary domain.

Abstract: There is provided a system and a method thereof for producing enhanced signals from an irreversible compression first processor in which there were performed irreversible compression encoding of signals and subsequently a compression decoding thereof. The method includes defining at least two sets of signals, wherein each set contains signals having a selected property of a signal, feeding the decoded signals of the first processor to a second processor, and processing the decoded signals by the method of projection onto convex sets, thereby imposing conformity to the sets of signals.
