Abstract: A method of routing voice communications is disclosed and includes receiving network event data at a telephone number mapping (ENUM) server of an originating network from a plurality of peering border elements associated with a plurality of peering communication networks. The network event data indicates a health status of each of the peering communication networks. The method also includes determining a network weight related to each of the peering communication networks based on the network event data, wherein each network weight indicates a proportion of calls that are to be routed from the originating network via the related peering communication network. The method further includes dynamically assigning a plurality of preference field values to session initiation protocol (SIP) addresses of the peering border elements within a plurality of naming authority pointer (NAPTR) records, based on the network weights.

Abstract: Systems and methods to select peered border elements for a communication session based on Quality-of-Service (QoS) are disclosed. In particular, an example method includes determining a composite QoS parameter of a communication session based on weighting QoS parameters of the session, the QoS parameters including a grade of service parameter of the session and a preferred mode of communication for a voice over Internet protocol (VoIP) device of a called party; querying a telephone number mapping server for a status of each of the peered border elements; assigning the session to be handled by a selected peered border element of the peered border elements based on the composite QoS parameter and the status of each of the peered border elements; and generating a QoS authorization token to reserve network resources associated with the selected peered border element.

Abstract: Efficient telephone number mapping (ENUM) based call routing during area code splits is described. An ENUM domain management component can associate an ENUM domain name with multiple records when a numbering plan area code split links an old area code of a telephone number corresponding to the ENUM domain name with a new area code. An ENUM provisioning component can perform permissive dialing of the old and new area code during ENUM based call routing by utilizing the multiple records.
