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.

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 IP 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 (SIP) 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, a computer-readable storage medium in a media controller having computer instructions to execute a soft-phone client application on the media processor, receive an audio call or a video call originating from an IP Multimedia Subsystem network where the calls are directed to the media processor by a gateway having a switch that routes the audio call or video call in accordance with a destination address included in a Session Initiation Protocol (SIP) header message, and selectively answer one of the audio call or the video call. The computer instructions can be operable to present an audio portion of the audio call through a speaker of a presentation device when an audio call is answered. Other embodiments are disclosed.
