Abstract: A private communications network and method of private communications network operation. One or more communications servers each have connected communications devices. From communications devices users enter called party numbers that may include a carrier access code (CAC) and carrier identification code (CIC). The called party number is checked for a CAC and any identified CAC/CIC is parsed from the called party number. The parsed called party number and the CAC/CIC are passed independently of each other over a private network to a public network gateway server. The public network gateway server directs the parsed called party number to a carrier network identified by the CIC, connecting the user to the called party.

Abstract: A call management technique implemented using a call routing engine is described. The technique of the present invention may be used to advantage to implement dialed number translation techniques in a global system connected to different telephone networks.

Abstract: A telephone accessory that is connected to a subscriber's telephone line as an extension, and monitors the line for the initiation of a call from any telephone set. The invention detects a call initiation by determining that a telephone set has seized the line without ring voltage being present immediately beforehand. If the first digit dialed by the subscriber is a “1”, the invention immediately dials the remainder of a long-distance access code, without the initial “1”, followed by a “1” which signifies a long distance number. This burst of dialed digits takes a short time, after which the subscriber continues to dial the area code and number as normal. The effect for the subscriber is to manually dial a normal long ditance nimber as 1+area code+number, while this invention takes advantage of the fact that long distance access codes begin with “1” and automatically inserts the desired code.

The computer program broadly comprises a code segment for receiving NPAs and NXXs for an area such as an MSA; a code segment for receiving information differentiating local calls from long distance calls for at least some of the NPAs and the NXXs in the area; and a code segment for analyzing the NPAs, the NXXs, and the information differentiating local calls from long distance calls and for automatically creating at least some of the call routing for calls originating in the area.

Abstract: A method and system enable optimization of trunk group design in a public switched telephone network (PSTN). A community of interest, including two end offices connected by a direct trunk and at least one tandem switch, is identified using out-of band signaling data collected from the PSTN. An application server interfaced to the PSTN determines whether traffic in the community of interest passes through the tandem switch during a predetermined time period. When traffic passes through the tandem switch, the application server further determines whether the direct trunk between the end offices experienced an overflow condition during the same predetermined time period. When the direct trunk did not experience an overflow condition, an exchange code associated with the traffic passing through the tandem switch is designated as a misrouted code. The misrouted code is flagged so that associated traffic is redirected through the direct trunk.

Abstract: A Carrier Identification Code (CIC) aware private communications network. International calls are placed with a CIC from a station at an originating server and routed over a private network to a connected public network gateway switch located in another country for a far-end hop-off. The public network gateway switch includes a CIC cross reference table with corresponding local CICs. The public network gateway switch replaces the original CIC with a corresponding local CIC from the cross reference table. Then, the call egresses from the public network gateway switch to a corresponding selected carrier network and connects to the called party on the public communications network.

Abstract: A method, and a switched network adapted to carry out the method, and computer-readable media carrying instructions for controlling the network, to increase the utilization of the North American Numbering Plan. Numbers that otherwise would be stranded in a low growth rate area are ported to a network switch serving another rate area. When a switch receives a called number it determines if the number is portable and, if so, accesses a database to determine if the number has been ported. If the number has been ported the switch processes the call in accordance with information linked to the number in the database so that stranded numbers can be assigned to stations without regard to the rate area in which the stations are located.

Abstract: Migration of a circuit-based-switch to a packet-based-soft-switch in a SS7 telecommunications network is accomplished with no disruption to subscriber service and retains and reuses the assigned signaling point code (SPC) of the existing circuit-based-switch. The system and method inserts a new soft-switch between an SS7 signaling transfer point (STP) and the existing circuit-based-switch in a way where traffic is split incrementally off the circuit-based-switch to the soft-switch so that no administrative changes are required at either the STP or the existing circuit-based-switch. The soft-switch is gradually cutover to act as a proxy STP and tandem switch for the existing circuit-based-switch and routes all calls to and from the network on behalf of the existing switch. The system makes use of multiple internal networks of the soft-switch to accomplish the controlled routing of bi-directional traffic.

Abstract: A private branch exchange (PBX) or other communication system switch processes a call to determine if an identifier associated with the call has a corresponding entry in a stored list of external endpoints registered with the switch. The switch directs the call to an external port of the switch for delivery to a given one of the external endpoints if the identifier associated with the call has a corresponding entry in the stored list of external endpoints registered with the switch. The given external endpoint does not have a fixed external port assignment in the switch. Instead, the switch dynamically selects from a set of external ports an available external port over which the call is directed to the given external endpoint. The dynamic selection of the available external port may be implemented using an automatic route selection (ARS) algorithm.

Abstract: An incoming call received in a private branch exchange (PBX) or other communication system switch at an external port of the switch is processed by the switch so as to appear to a destination terminal as if it were originated by an internal extension associated with the switch. The incoming call may be from a mobile telephone or other originator terminal that is utilizable external to a premises serviced by the switch and does not have an extension associated with any internal endpoint serviced by the switch. The switch attempts to map an identifier associated with the incoming call to a corresponding entry in a stored list of external endpoints registered with the switch. If the identifier has a corresponding entry on the list, the switch processes the incoming call such that it appears to the destination terminal as being originated by an assigned internal extension. For example, an internal alerting indicator and associated station display may be provided at the destination terminal.

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 new destination number determination switching system is provided for a telecommunications environment in which a called party has discontinued an old called party destination number and obtained a new called party destination number. The new destination number determination switching system is used to obtain the new called party destination number when a calling party places a call to the old called party destination number. The switching system includes a hub switch that receives a rerouted call from a corresponding original destination switch. The hub switch corresponds to a routing number prefix used to reroute calls from the corresponding original destination switch to the hub switch. The routing number prefix causes the hub switch to initiate a trigger to a network platform that obtains the new called party destination number.

Abstract: A universal triggerless number portability routing node receives a first call setup message from an end office. The triggerless number portability routing node may examine a first routing number (RN) value contained in the first call setup message to determine whether the first RN is a home RN value. If the first RN is determined to be a home RN value, a number portability database lookup is performed based on the called party dialed number. Once a number portability lookup is performed, the call setup message is modified to include a second RN value returned by the NP database, and the modified call setup message is routed to a destination node, which may be a tandem gateway or an end office/mobile switching center.

Additional steps may be made in response to the telephone number wherein more accurate information is gathered and utilized to ensure the reliable determination of the identity of the entity responsible for ultimately billing the called party.

Abstract: It is typical that a user calls an information assistance service provider to request information, e.g., a destination telephone number desired by the user, and chooses to be connected to the destination number. It is also typical that the information assistance service provider offers enhanced assistance service features, e.g., a StarBack feature. In prior art, to provide the enhanced service features, the user's call invariably continues to be connected to a servicing switch associated with the service provider after the user is connected to the destination number. To efficiently utilize the limited capacity of the servicing switch, in accordance with the invention, the user's call may be selectively released from the servicing switch before the call is connected to the destination number. Such a call release depends on certain criteria for determining whether the user is a candidate for utilizing an enhanced service feature after the call is connected to the destination number.

Abstract: The invention relates, inter alia, to a method in which an identifier is assigned to a terminal, said identifier being independent of an operator who operates the terminal. In a switching device, the identifier is used to determine a service providing program by means of which a communications service can be used from the terminal. For the service providing program which is determined, settings are then made as a function of the operator who operates the terminal.

Abstract: A telephone call logging system includes a database containing identifiers and optionally call control limitations assigned to the identifiers. Call control limitations may include budgetary, time, geographic, and other limitations to a call. A telephone line is subscribed to the system, and users of the line are provided identifiers which may have one or more of the call control limitations. When making an outgoing call, the telephone network queries the database and determine whether the telephone line is subscribed. If the telephone is subscribed, the telephone network communicates with a server which requests the user to enter the identifier. It is then determined which, if any, call control limitations, are placed upon the user and whether and for how long the call can be connected. The call and its disposition are recorded in a log preferably accessible via the Internet.
