Abstract: A switched telephone network is arranged in a manner to enable packet voice communication between telephone terminals via multiple redundant packet switched networks. The packet switched networks may utilize different protocols, be operated by different entities, and have primary functions other than voice communication. One example of such a network may be internetworked networks, such as the Internet. One example of an alternate packet switched network may be a network whose primary function is control of a circuit switched telephone network. The common channel interoffice switching system (CCIS) of a public switched telephone network (PSTN) is a preferred example. A voice communication link may be established from telephone terminal to telephone terminal via the Internet, the quality of voice communication may be monitored, and the link may be transferred to the common channel interoffice signaling network if and when the quality of voice communication deteriorates beneath a pre-established norm.

Abstract: A system and method of affecting transfer of a message such as a voice message from one centralized messaging system in a first switched telephone network to a centralized messaging system in a remote second switched telephone network wherein each of said telephone networks includes central offices connected to subscriber terminals. The message is inputted in analog form into one of the terminals connected to the first telephone network and stored in digital form in the centralized messaging system in that network. The message is then transferred from that centralized messaging system to the centralized messaging system in the second telephone network where it is stored. The message is then delivered by retrieval or an outgoing call to an addressee terminal in the second telephone network. The transfer between telephone networks and their respective centralized messaging services occurs via an internetwork to which each of the centralized messaging systems are connected.

Abstract: A system and method of effecting transfer of a message such as a voice message from one multipurpose, multimode centralized messaging system in a first switched telephone network to a multipurpose, multimode centralized messaging system in a remote second switched telephone network, wherein each of the telephone networks includes central offices connected to subscriber terminals. The message is inputted in analog or digital, voice or text form by one of the terminals connected to the first telephone network, selectably processed in the messaging system and stored in a selectable digital form in the messaging system in that network. The message is then transferred from that messaging system to the centralized messaging system in the second telephone network where it is selectably processed and stored. The message is delivered by an outgoing call to an addressee terminal in the second telephone network.

Abstract: An Intelligent Peripheral (IP) is used in combination with both narrowband type services (e.g., voice mail) and broadband type services (e.g., video transmission) and may provide protocol conversion, message translation, speech recognition, message editing and/or message-to-text conversion. The IP has a gateway switch between the various internal processing modules and the network line or trunk connections. The gateway switch provides selective routing of incoming calls to the appropriate modules, some modules providing narrowband type services and other modules providing broadband processing.

Abstract: A system and method of effecting transfer of a message such as a voice message from one centralized messaging system to another centralized messaging system in a switched communications network having a plurality of central offices connected to subscriber terminals and connected together by trunks wherein the transfer of the message is effected through a common channel signaling network without using the trunks.

Abstract: An intelligent network, such as might provide telephone services or the like, comprises local communication links, one or more trunk circuits and a number of separately located central office switching systems. The network selectively provides switched call connections between at least two of the local communication links. The switching systems also exchange signaling messages via an interoffice signaling network, as part of the procedures for establishing call connections. The interoffice signaling network includes an Intelligent Signaling Transfer Point (ISTP) which communicates with the switching offices via signaling links that are separate from the local communication links and the trunk circuit(s). In accord with the present invention, the ISTP includes a database storing call processing data associated with a plurality of the local communication links for control of call processing through one or more of the central office switching systems. The ISTP also includes a program controlled processor.
