Abstract: Methods, devices, and systems for smart load balancing are provided. SIP Requests destined for a particular AOR are delivered to one of several registered contact addresses according to associated availability score stored in routing element's contact resolution table. The availability score is periodically updated by the contact entity itself using the SIP PUBLISH mechanism to push the score to the routing element.

Abstract: A topic is associated with a temporary communications address such as a temporary telephone number. This assignment may be effected by the user when the temporary address is obtained by the user. Illustratively, a user who simultaneously uses a plurality of temporary addresses associates a different topic with each of those addresses. When a caller calls the temporary address, the call is redirected to the user's real address and the user receives the topic that is associated with that temporary address, and preferably also the called temporary address itself, along with the redirected call, and this information is either displayed or announced to the user. The information provides context for the call to the user, and may optionally be captured in call logs. Illustratively, when the user initiates a call via the temporary address or the topic, the temporary address or the topic is provided to the called party as the caller ID information. The user's identity is thus kept secret.

Abstract: Provided are methods, devices, and systems for maintaining a SIP survivable User Agent. The present invention is adapted to allow the User Agent to detect the status of the network, thus providing the User Agent to perform failover/failback operations. The User Agent may be adapted to determine the status of the network based on its own monitoring mechanisms and/or based on messages received from other network components.

Abstract: Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention is adapted to allow SIP endpoints or User Agents to discover and select the controller or controllers that the SIP endpoint will register with. Selection of the controller or controllers may be based upon the relative attributes of the controllers and the needs of the SIP endpoint.

Abstract: Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention may utilize messages, such as SIP NOTIFY messages, to trigger various network components to failover and failback based on the determined status of the SIP network.

Abstract: A presence aware communications system, that includes a messaging system configured to perform one or more of provide a subscriber's communication device with information regarding an incoming contact during a messaging session between the subscriber's communication device and the messaging system, provide the subscriber's communication device with a text message containing information regarding one or more messages when a notification is received that the subscriber's communication device is available, provide the subscriber's communication device with a text message relating to a voice message from a different first party received by the messaging system, in response to the subscriber's communication device requesting a connection with at least one of an inputted telephone number and address, provide the subscriber's communication device with a notification respecting at least one eligible message from a second party associated with the at least one of an inputted telephone number and address, while a conta

Abstract: A low-cost, high-temperature heat exchanger is made from a notched piece of metal, the metal being folded back and forth upon itself to form a monolith. The notches in the metal piece create openings, communicating with distinct sides of the monolith. Ducts are attached to the openings. Cut pieces of corrugated metal, which may have a catalyst coating, are inserted between folds of the monolith. The heat exchanger may be used as part of a fuel cell system, or in other industrial applications, to recover waste heat, or to conduct various catalytic and non-catalytic reactions. The invention also includes an element, or building block, for a high-temperature heat exchanger, including a folded metal monolith with metal combs inserted, the monolith and the combs defining seams which are hermetically sealed.

Abstract: A presence aware communications system, comprising a messaging system configured to perform at least one of the following operations: (a) provide a subscriber's communication device with information regarding an incoming contact during a messaging session between the subscriber's communication device and the messaging system; (b) provide the subscriber's communication device with a text message containing information regarding one or more messages when a notification is received that the subscriber's communication device is available; (c) provide the subscriber's communication device with a text message relating to a voice message from a different first party received by the messaging system; (d) in response to the subscriber's communication device requesting a connection with at least one of an inputted telephone number and address, provide the subscriber's communication device with a notification respecting at least one eligible message from a second party associated with the at least one of an inputted tel

Abstract: A telephony trainer and exerciser allows a user of the telephony system to practice and train using the telephony system and its various features. The telephony trainer and exerciser system provides at least one automated responder, and more preferably, a plurality of automated responders that can be called by the user, thereby allowing the user to practice different operating features of the telephony system. Using a recognizer agent, the automated responders are able to distinguish between commands given by the user and similar statements given by another automated responder. The trainer and exerciser system optionally includes a correlator agent to provide an audio and/or written transcript of the practice session. A coaching feature is also optionally provided to assist a user in operating the trainer and exerciser and/or the telephony system.

Abstract: A method and apparatus route telecommunication calls in a communication system based on media type by detecting a requirement for a special media type for a telecommunication call; and selecting a subset of a plurality of gateways wherein only the subset of gateways is capable of providing communication for the special media type.

Abstract: A gauge system determines the thread pitch diameter of an internally or externally-threaded article and includes a standard measuring caliper with styli selected and fitted into the caliper to correspond to a particular thread type and pitch. The styli are mounted into the caliper to provide a reference zero position to the calipers for either externally or internally-fitted articles. A processor is associated with the calipers and styli and is of a type which is configured for hand-holding. The processor has input buttons for inputting a descriptor of internal or external threads, thread type and thread pitch. The processor software receives and processes information received from the caliper to calculate the thread pitch diameter. A display connected to the processor presents the thread pitch diameter.
