Abstract: A method and system for providing intelligent network control services in IP telephony, wherein the system includes a location manager and an IP telephony proxy server. The location manager includes an interface to a legacy telephony service control entity and the IP telephony proxy server includes an IP interface to the location manager. If the IP telephony proxy server requires intelligent network services, then the IP telephony proxy server sends an IP telephony session initiation request to the called party at the location manager. The location manager uses the information to query the legacy telephony service control entity for routing information. When the location manager receives a routing response from the service control entity, the location manager maps the response to an IP telephony session control message back to the IP telephony proxy server.

Abstract: The present invention is directed to a method for placing a call between a client in one network and a client in another network. The IP network includes a SIP server and a network gateway configured to provide access to a public switched network. The method includes receiving a SIP call request message from the first client. The SIP call request message is authenticated to thereby identify an authentic originating client. Subsequently, a database is searched to find client billing tag corresponding to the authentic originating client. The call is completed if the client billing tag is obtained, and not completed if the client billing tag cannot be obtained. Thus, the present invention provides an efficient method for billing phone calls that are placed from SIP enabled devices to a telephone connected to the Public Switched Telephone Network (PSTN). The method of the present invention also substantially eliminates certain types of fraud.

The system transports IP media for the session between the calling party and the first device, and between said called party and a second device. The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session.

Abstract: A method, system, and computer program product for controlling customer resources for Internet protocol (IP) traffic delivery are disclosed. The network utilization of a group of endpoints on a network is tracked to generate group utilization level information corresponding to a current amount of network resource consumption by the group of endpoints. A request for network resources for a data flow for an endpoint in the group is received from a router associated with that endpoint. The request for network resources includes an identifier associated with the endpoint. A determination is made whether to accept the request based on the group utilization level information, the identifier, and a first predetermined profile associated with the group and including a first network utilization limit.

The intelligent network includes a multi-service control point, an ATM signaling intercept processor, and a service administration. The multi-service control point receives an input extracted from an input ATM setup message that includes a called party phone number value and a VToA designator, and generates an alias ATM address of a called party CPE that corresponds to a network gateway in communication with a PSTN switch through a plurality of trunk lines and a desired trunk line of the plurality of trunk lines. The multi-service control point generates an output in response that will be used to generate an output ATM setup message that includes the alias ATM address.

Abstract: A method of routing a telephone call includes receiving an indication, at a handset device 112, to initiate a telephone call. It is then determined, preferably by the handset device 112, whether the telephone call is an emergency services telephone call. If the telephone call is not an emergency services telephone call, it is routed to a proxy server 134. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gateway 116 without first accessing the proxy server 134.

Abstract: An approach is provided for supporting telephony services over a data communication network. A network server receives multiple early media streams associated with a communication session between an originating network element and one or more terminating network elements. The network server selectively suppresses the early media streams, such that the originating network element receives a single signaling message indicating status information of the communication session (or call). The present invention has particular applicability to SIP (Session Initiation Protocol) IP (Internet Protocol) telephony services.

Abstract: An illustrative intelligent network and method for providing voice telephony over Asynchronous Transfer Mode (“ATM”) and private address translation are provided that can provide significant advantages. The method includes generating an input ATM setup message at the calling party CPE that includes a VToA designator and a called party phone number, extracting information from the input ATM setup message, analyzing the information, designating an ATM address of a called party CPE to be stored in the first parameter of an output ATM setup message, determining if private address translation is needed, designating the ATM address of the called party CPE to be stored in a first instance of the second parameter of the output ATM setup message, designating an ATM address of an egress ATM edge switch to be stored in the first parameter of the output ATM setup message, and generating an output ATM setup message.

Abstract: In a SIP network, SIP servers are provisioned with information used to authenticate subscribers and entities that will be placing calls. This information can be used during call establishment to allow or deny calls, as well as to determine the appropriate party to bill if the call involves a charge, such as a long distance charge. In addition to allowing calls between authenticated and trusted entities, there is a need for the SIP server to allow certain kinds of calls that involve non-trusted users or entities. If non-trusted entities where not recognized, trusted users and entities within the SIP network would not be able to receive calls from users or entities not know to the SIP server that is providing them services.
