Abstract: A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium in a media controller having computer instructions to execute a soft-phone client application on the media processor, receive a call originating from an internet protocol multimedia subsystem network where the calls are directed to the media processor by a gateway having a switch that routes the call in accordance with a destination address included in a session initiation protocol header message, and selectively answer the call at any of a plurality of terminal devices including a mobile cellular phone coupled to the media processor via a femtocell. The computer instructions can be operable to present an audio portion of the call through a speaker of a presentation device operatively coupled to the media processor. Other embodiments are disclosed.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at a mobile switching center server, transmitting a mapping query from the mobile switching center server to a database in response to the request for the voice call, route the request from the mobile switching center server to an internet protocol multimedia subsystem for facilitating establishing the voice call when the mapping query is successful in obtaining an internet protocol address for establishing the voice call with a recipient communication device, and routing the request from the mobile switching center server to a second server for facilitating establishing the voice call without routing the request to the internet protocol multimedia subsystem when the mapping query is not successful in obtaining the internet protocol address. Other embodiments are disclosed.

Abstract: 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.

Abstract: Aspects of the subject disclosure may include, for example, determining from a transport protocol message, capability information associated with user equipment associated with a call session, determining a first codec to provide a first media service to the user equipment associated with the call session according to the capability information, and responsive to determining the first codec, searching a codec table to obtain a first resource identifier associated with a first media resource function to provide the first media service according to the first codec. If the first resource identifier associated with the first codec is not available at the codec table, accessing the first resource identifier associated with the first media resource function from a domain name server and, in turn, transmitting a first request to the first media resource function to provide the first media service to the user equipment associated with the call session. Other embodiments are disclosed.

Abstract: In one embodiment, a method and apparatus for resolving domain name system queries using unique top-level domains in a private network space are disclosed. For example, the method determines that a domain name service query specifies a destination residing in a private network space rather than in a public Internet space. The method then routes the domain name service query to a top-level domain name service server associated with the private network space, without routing the domain name service query to a root domain name service server in the public Internet space. The top-level domain name system server resides in the highest level of a hierarchy of domain name system servers belonging to the private network space.

Abstract: Aspects of the subject disclosure may include, for example, a method and system to interconnect a first communications carrier to a second communications carrier by receiving a request to connect a communication from a first carrier to a second carrier; modifying a private ENUM (tElephone NUmber Mapping) domain of the request to include an intercarrier ENUM apex based domain; retrieving a routing record using a domain name server (DNS) indicated by the intercarrier ENUM apex based domain; and routing the communication to the second carrier using the routing record. Other embodiments are disclosed.

Abstract: A method, apparatus and computer-readable medium for identifying a subscriber home domain in a communication network are described. A national subscriber profile is partitioned into regions and a NAPTR resource record is modified to identify in which region a particular subscriber is located. In response to a calling party requesting that a connection to a called party be established, a database is queried to provide a modified NAPTR record which identifies the region in which the called party is located. A connection can then be established without polling each region.
