The notification server is fit to register an identifier of first terminal (1) and to transmit the identifier to the second terminal (4) after the second terminal has become accessible. Monitoring means (5) monitor the accessability of the second terminal. The notification server (6) registers e.g. the calling line identifier of the first terminal (1) and calls, after the second terminal (4) has become accessible, the second terminal (4), transmitting an artificial calling line identifier having the value of the calling line identifier of the first terminal, registered by the notification server. The call to the second terminal (4) is aborted as soon as the identifier has been transmitted to the second terminal.

Abstract: An enhanced computer telephony (CT) network design for a private branch exchange (PBX) telephone system network improves the computer telephony interface (CTI) capabilities of the network. Bi-directional data from remote telephone switching nodes of different PBX systems, each using a common software application, is combined into a single data stream by the network to simplify control of the remote PBX systems. Commands to, and events received from, the different PBX switching nodes are combined by use of a gateway to automatically and transparently route digital information for control of the correct remote system node.

Abstract: To protect the privacy of a user subscribing to a mobile telephony operator, the operator produces an isolating identifier by which the user can link up anonymously with a content provider. The operator/producer is the only entity capable of relating the isolating identifier to the user on request. An isolating identifier is, furthermore, either an isolating session identifier, hence one that changes at each connection of a user to a provider, or an isolating context identifier, hence one that persists over several connections. Furthermore, a context identifier is proper to a user/provider pair. This even further isolates the user. The format of the isolating identifier is compatible with the format of the NDS field, defined in the telephony standards.

Abstract: An efficient and improved dynamic home agent discovery algorithm and system to be used in a protocol for network communications. The present invention encapsulates and integrates communications of the home agents into a single home agent communication. Communication between a mobile node and the home agents is simplified to a single home agent communication. Dynamic home agent discovery processes are performed, based on the single home agent communication. Encapsulation is achieved by having each of the home agents maintain a home agent list that contains information about each of the home agents coupled to the home link. A designated home agent receives and processes home agent discovery requests from the mobile node on behalf of home agents coupled to the home link, and a designated home agent sends home agent advertisements to and communicates with the mobile node.

Abstract: Within a network environment, redundant capabilities for exchanging call-processing signals enhance reliability of telephony support for telephony endpoint devices. A data network, such as a telephony-over-local area network, provides primary support for the telephony endpoint devices, which may be telephony-enabled computers or Internet Protocol telephones. A second network has a first mode in which it is inactive with respect to telephony traffic to the telephony endpoint devices, but has a second mode in which call-processing signals are routed through the second network in response to a determination that the data network is disabled. As a result, telephone features such as call deflection may be continued when the primary support is disabled.

Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request.

Abstract: A network element management system which can exploit the customized interface features of a variety of versions of a variety of complex system products from a variety of manufacturers. This is done by maintaining a meta-model, which is not itself a model until instantiated, of the possible known product configurations to be interfaced to. Once the meta-model is instantiated, it provides configuration parameters which the interface program uses to build a correct configuration for the management and/or monitoring interface. This is particularly advantageous in the preferred embodiment of a telecommunications network element management system, but also has potential applicability to other large “supersystem” applications.

Abstract: A method for optimizing an established call routed across a network from an originating exchange to a destination exchange over a first connection path. The first connection path features a path metric of interest, such as administrative weight. A second connection path is identified which features an improved path metric, the path is made operative and the call is directed over the second connection path. Thereafter, the first connection path may be dismantled. The second connection path is preferably identified by signalling a call set-up message over the network, wherein the message incorporates a reporting field and each transiting exchange propagating the message updates the reporting field until it specifies the path metric of the replacement connection path traversed by the call set-up message. A connect message incorporating the reporting field back is signalled back to the originating exchange from the destination exchange.

Abstract: A method of and apparatus for supporting intelligent call routing (ICR) systems multiple vendors, in a vendor neutral fashion using a computer is described. One embodiment has a voice program send a call routing request using an HTTP format to a call routing program. The call routing program decodes the HTTP request and identifies the appropriate vendor-specific communication format and communications method for talking to the ICR system specified in the HTTP request. The call routing program sends the request and receives the answers from the ICR system in the vendor specific formats. The call routing program provides the ICR system response back to the voice program in a vendor neutral fashion. This approach allows voice programs to easily be written that work with multiple ICR systems and allow component reuse of call routing code amongst programs that end up working with multiple systems.

Abstract: A method and system for establishing a local call from a payphone by a customer through long distance carrier switches. The payphone customer dials a long distance provider primary intralata carrier (PIC) code followed by a number sequence. The local call is routed to a long distance provider switch using the long distance provider PIC code. The payphone call is then routed to a voice response unit (VRU) using the number sequence. The VRU prompts the payphone customer to select local calling from the VRU menu, enter a destination number, and to enter their long distance calling card information. The system then verifies that the customer's calling card account is active and connects the call.

Abstract: A method and apparatus are disclosed for automatically translating the dialed string entered by a calling party to identify a called party into another dialed string. The string translation may be based, for example, on characteristics of the telephone number or telephone terminal of the calling party or characteristics of the call itself. Translation rules translate the dialed string entered by the calling party to another dialed string. Each translation rule contains one or more conditions and a corresponding action item that should be performed to translate the dialed string when the rule is satisfied. The improved abbreviated dialing feature allows a shorter sequence of digits dialed from any telephone connected to a compliant switch to be replaced by a longer dialed string.

Abstract: Automated call routing systems and methods are described. In one implementation, a speech recognition directory system facilitates the routing of callers based upon stored results of recent disambiguations, which may be stored in heuristic profiles that are associated with callers. Instead of requiring a caller to process a series of disambiguation attempts, in which secondary information is presented for the caller's approval, this call routing scheme leverages the fact that the user is likely seeking a person they've previously contacted. In large directories, this call routing scheme improves the speed of the transaction and eliminates the frustration of the disambiguation process. Rather than pursuing a disambiguation process with the caller, the call routing system may immediately announce the transfer. The caller may abort the process if the selected call destination is incorrect.

Abstract: A system for providing termination information for an international telephone number includes a centralized database of terminating characteristics. The system may also include request processing logic that receives an international telephone number from a user. In response to receiving the telephone number, the request processing logic may automatically query the centralized database to obtain information that indicates whether the telephone number uses wireless termination. In response to obtaining the information from the centralized database, the request processing logic may automatically transmit to the user a response that indicates whether the telephone number uses wireless termination. The system may also include a database engine that uses a tree structure of linked nodes to perform a longest matching prefix search on the telephone number in response to the request processing logic querying the centralized database.

Abstract: A method is disclosed for designing a signaling network of call coordinators (CCs) for internet telephony. The new method can be used to design a CC network of arbitrary size that satisfies, with high probability, limitations on the maximum number of sockets per CC and on the maximum number of hops between an arbitrary pair of switches in the network. According to the disclosed method, the network of CCs is treated initially as a collection of isolated points, one point for each CC. Then, links are added between pairs of CCs, excluding pairs lying within the same switch. The links are added randomly, but with a particular probability p, which may be different for different pairs. Thus, whether a given link is added depends, in effect, upon the outcome of a loaded coin toss in which the probability of a positive outcome is p.

Abstract: A method and apparatus for unified overlay dialing enables simplified telephone dialing to occur within a standard overlay area and eliminates disruption dealing with area code saturation. Each three-digit area code within an overlay area is associated with a single-digit suffix, with the parent area code obtaining the suffix “0”. Intra-overlay area dialing then proceeds on the basis of a seven digit number plus a one-digit suffix, rather than a full 10 or 1+10-digit number. For dialing to the parent area code from within the overlay area, the suffix may be omitted entirely, and the expiration of a suitable timing delay causes the seven digit number provided to be dialed into the original (parent) area code. This method can be implemented in connection with a telephone company central office switch, a modified custom calling service or be made accessible to individual telephone subscribers using computerized customer premises equipment.
