  • Patent number: 9185212
    Abstract: Devices, systems and methods are disclosed for selecting and sending one of a plurality of responses to a call on a communications device. A user may select a default response or a custom response. When the user receives a call to a communications device, a set of responses is displayed on the communications device to facilitate selection by the user. A response includes a message and a call processing command. A message is in the form of an audio clip, text message, webpage, picture, video, etc. A call processing command, such as “accept call”; “reject call with voicemail”; “reject call without voicemail”; “place caller on hold”; “forward call to 555-555-5555”; “I will call you back”; etc. is performed along with the message. This plurality of responses can be organized by the user in groups associated with classes of callers, such as friends, family, co-workers, etc. In this manner, the responses available to the user when a call is received changes depending on the caller.

  • Patent number: 9184940
    Abstract: A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request. The method queries an tElephone NUmbering Mapping (ENUM) server for a called party of the session request, and determines if at least one Naming Authority Pointer (NAPTR) resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier (SIP URI) is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.

  • Publication number: 20150309708
    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.

  • Patent number: 9137269
    Abstract: Methods and apparatus for handling a communication session for an unregistered Internet Protocol Multimedia Subsystem (IMS) device are disclosed. An example method includes, in response to receiving an internet protocol multimedia subsystem session initiation message from a user endpoint, determining whether the user endpoint is registered; and, when the user endpoint is determined to be unregistered: determining whether the internet protocol multimedia subsystem session initiation message is directed to an exception endpoint by performing a lookup on a list; determining whether a profile for the unregistered user endpoint is available; when the profile for the user endpoint determined to be unregistered is unavailable, loading a default profile; and establishing an internet protocol multimedia subsystem session on behalf of the user endpoint determined to be unregistered when the internet protocol multimedia subsystem session initiation message is directed to the exception endpoint.

  • Publication number: 20150244745
    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.

  • Publication number: 20150215660
    Abstract: Aspects of the subject disclosure may include, for example, identifying a request to record video content at a multimedia storage device, wherein the video content corresponds to a program having a scheduled broadcast time that occurs during a peak viewing period. Data is obtained to prevent viewing of the video content prior to the broadcast time. The video content, responsive to the identifying of the request, is sent selectively to the multimedia storage device during a non-peak viewing period prior to the peak viewing period. The video content includes the data to prevent the multimedia storage device from sending the video content to another device prior to the time when the program is scheduled to be broadcast. Other embodiments are disclosed.
