Abstract: A system and method of delivering ringback audio content are disclosed. In one embodiment, the method includes receiving a connection request at an originating serving call session control function (S-CSCF) network element. The connection request indicates that a caller device has placed a call to a destination device associated with a ringback audio content service subscriber. The method also includes receiving a plurality of naming authority pointer (NAPTR) records at the originating S-CSCF network element from a telephone number mapping (ENUM) server. The NAPTR records include a plurality of ringback audio uniform resource indicators (URIs) associated with the destination device. The method also includes modifying the connection request to include the plurality of ringback audio URIs.

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.

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: A method that incorporates teachings of the subject disclosure may include, for example, determining at a first directory server of a first regional call processing system whether a new name authority pointer associated with a telephone number is within a first geographic region of the first regional call processing system, transmitting the new name authority pointer to a first name server of the first regional call processing system for provisioning the name authority pointer to the first name server responsive to determining that the telephone number is located within the first geographic region, and transmitting the new name authority pointer to a second directory server for provisioning the new name authority pointer to a second name server of a second regional call processing system responsive to determining that the telephone number is not located within the first geographic region. Other embodiments are disclosed.

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: An aspect of the subject disclosure may include, for example, receiving a request from a communication device to initiate a communication session in a packet-switched network, obtaining a first name authority pointer record responsive to determining that there is an undesirable operational state in the packet-switched network, wherein the first name authority pointer record comprises a null record, obtaining a second name authority pointer record responsive to determining that there is a desirable operational state in the packet-switched network, wherein the second name authority pointer record comprises a record, and initiating the communication session according to one of the first name authority pointer record or the second name authority pointer record. Other embodiments are disclosed.

Abstract: An architecture is described that can enhance and/or simplify tactile-based I/O transactions in connection with a user-interface (UI) of limited form factor. In particular, the architecture can monitor a position of a selector object such as an operator's finger relative to a UI display as the selector object hovers or moves above the UI display. Based upon this position, an analogous coordinate in the UI display can be determined, and a portion of the UI display substantially centered at the coordinate can be modified. As one example, the UI display can be modified to increase the magnification scale (e.g., a virtual magnifying glass) of the portion of the display indicated by the selector object.
