Abstract: A network may include a method that includes, for example, receiving a communication request responsive to a telephone number mapping query failure, where the communication request is initiated by an originating communication device requesting a communication session with a terminating communication device, foregoing initiating the communication session as a circuit-switched communication session responsive to determining that the originating communication device and the terminating communication device are enabled to use packet-switched communications, and instructing a second network node to initiate the communication session as a packet-switched communication session between the originating communication device and the terminating communication device responsive to the determination. Other embodiments are disclosed.

Abstract: A method includes receiving, at a network component of a first carrier network from a source device, a telephone number of a destination device configured to communicate via a second carrier network. The method further includes in response to a query message sent to a telephone number mapping device of an internetwork packet exchange network, receiving a name server record at the network component, the name server record indicating a domain name associated with a second telephone number mapping device of the second carrier network. The method also includes in response to the network component sending the domain name to a domain name server of the internetwork packet exchange network, receiving an Internet protocol address of the second telephone number mapping device. The method includes sending, from the network component to the second telephone number device, a second query message based on the Internet protocol address.

Abstract: Techniques for validating alignment between network element configuration and DNS records associated with a communication network are presented. Alignment management component (AMC) can retrieve respective configuration parameter data items relating to respective configuration parameters associated with respective resource-related identifiers, and respective metadata items associated with the respective resource-related identifiers, from a configuration data store; and retrieve respective DNS records from respective DNS name servers, based on analyzing the respective metadata items associated with respective DNS records. For each resource-related identifier that is supposed to have a corresponding DNS record, based on the result of analyzing the respective configuration parameter data items and respective DNS records, AMC can determine whether the resource-related identifier has a corresponding DNS record stored in the DNS name server indicated by the metadata item. AMC can generate an audit report comprising a missing DNS record data item for each DNS record determined to be missing.

Abstract: Aspects of the subject disclosure may include, for example, providing a request associated with a call session to a server, wherein the request includes capability information associated with user equipment. A codec is identified according to the capability information to obtain an identified codec, which facilitates media service to the user equipment. The media service is accessed from a media resource function, which in turn, is accessed by the server responsive to the identified codec. An operable resource identifier is identified responsive to a search of a codec table, wherein the server accesses the operable resource identifier associated with the media resource function from a domain name server responsive to the resource identifier not being available at the codec table. Other embodiments are disclosed.
