Concepts and technologies pertaining to enabling internet protocol carrier peering to foreign network domains are provided. A method includes identifying, by a computer system executing within an originating carrier network, a plurality of numbering plan area identifiers corresponding to a receiving carrier network. The method further includes accessing, by the computer system executing within the originating carrier network based on the plurality of numbering plan area identifiers, a plurality of numbering plan area zone file records stored on a private enabled telephone number mapping server. The method also includes creating, by the computer system executing within the originating carrier network, a single instance of a name authority pointer record placeholder within each of the plurality of numbering plan area zone file records stored on the private enabled telephone number mapping server.

Enabling internet protocol carrier peering to foreign network domains

Methods and apparatus to achieve internetwork connectivity. Initiation is detected, by a first device on a first network, of an internet protocol (IP) connection with a second device on a second network, wherein the first network includes a plurality of egress devices that are configured to send requests for inter-network connection information. A subset of the egress devices are selected, wherein each of the subset of egress devices are configured to query for connection information relating to the second network. The subset of devices are caused to query the at least one other network for the connection information relating to the second network. The connection information is received relating to the second network. The connection information is caused to be used in establishing the IP connection between the first device and the second device.

Methods and target architecture for enabling IP carrier peering

Methods and systems may provide carrier ENUM based routing for subscriber devices (e.g., voice or other multimedia services over IP) to locate and to connect to subscriber devices of another IP peering carrier. A private ENUM database may be used to connect subscribers of disparate carriers using a domain for designated breakout gateway control functions.

Enabling IP carrier peering

Methods and apparatus to achieve internetwork connectivity. Initiation is detected, by a first device on a first network, of an internet protocol (IP) connection with a second device on a second network, wherein the first network includes a plurality of client devices that are configured to send requests for inter-network connection information. A subset of the client devices are selected, wherein each of the subset of client devices are configured to query for connection information relating to the second network. The subset of devices are caused to query the at least one other network for the connection information relating to the second network. The connection information is received relating to the second network. The connection information is caused to be used in establishing the IP connection between the first device and the second device.

A method and apparatus for enabling a call originated in the VoIP network to be routed from the egress of the VoIP network to the terminating PSTN network using an egress route, such as an appropriate egress access trunk, that is in the same Local Calling Area (LCA) of the called party number are disclosed. This allows the call to be completed to the called party without paying access charge. For example, the method assigns a Billing Telephone Number (BTN) or a Charge Number (CgN) to an egress route between a communication network and a Public Switched Telephone Network (PSTN) network. The method then routes a call originating from the communication network and terminating to the PSTN network using the egress route without incurring an access charge.

Method and apparatus for providing enhanced services local routing

A method and apparatus for providing email notification for called and/or calling parties of a call placement are disclosed. The method enables a packet network service provider, e.g., a VoIP or SoIP service provider, to register customers for email notification service, to obtain the disposition of calls from Call Detail Records (CDRs), call control elements or application servers that have access to call signaling information in real time, to identify calls that resulted in ringing without an answer or busy disposition, and to determine whether or not the called and/or calling party subscribed to the email notification service. If the calling and/or called party subscribe to the notification service, the service provider sends an email notification to the calling and/or called party containing the caller and called party information, the time of the call, the disposition of the call and the like.
