20080298358 | Method and apparatus to control access to content - The present invention provides a method, apparatus and computer program product for accessing content via a packet-switched network based on a content access policy. The content is marked with a rating. The rating is extracted from the content, to verify conformance with the content access policy. On verification of the conformance between the rating and the content access policy, access to the marked content is provided. | 12-04-2008 |
20100067668 | INTEGRATING TELEPHONY AND VOICE MAIL ROUTING - A data processing system comprises call processing logic comprising a voice mail subsystem, or a call management subsystem configured to process voice-over-IP (VoIP) calls, or both a voice mail subsystem and a call management subsystem; service advertisement logic coupled to the call processing logic and operable to send one or more service advertisement messages by unicast to a remote peer data processing system that is also configured with compatible service advertisement logic, wherein the remote peer data processing system is located in a different LAN segment than the data processing system; and each service advertisement message comprises one or more network addresses associated with the call processing logic, and one or more data sets each comprising an identifier value, a first value that indicates that the identifier value is associated with a telephone extension, and a second value that indicates that the identifier value is associated with a voice mailbox. | 03-18-2010 |
20110044326 | IDENTIFY A SECURE END-TO-END VOICE CALL - We describe a system embodiment comprising generating a Secure Real-Time Transport Protocol (SRTP) encapsulated packet and including a secure media indicator into the SRTP encapsulated packet. The method further comprises inserting the SRTP encapsulated packet into an SRTP voice stream associated with an active call between a source and a destination endpoint and indicating an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator. | 02-24-2011 |
20110216153 | DIGITAL CONFERENCING FOR MOBILE DEVICES - The present embodiments may relate to video conferencing. A conferencing gateway receives a video signal from one or more conferencing devices that are participating in a video conference. The video signal is adjusted to conform to the one or more mobile conferencing device specifications, such as display size, resolution, frame rate, or bandwidth. The adjusted video signal is transmitted to a mobile conferencing device for display. | 09-08-2011 |
20130003720 | SYSTEM FOR AD-HOC COMMUNICATION SESSIONS - In one implementation, a guest device on an ad hoc network is permitted to initiate a communication session through a packet switched network depending on the destination endpoint of the communication session. A network device maintains a list of approved destination endpoints, which may be identified by telephone numbers, addresses, or uniform resource identifiers. The approved destination endpoints correspond to services that are offered to users of guest devices, such as voicemail, videoconferencing, or customer service. The network device receives a request for a communication session from a guest device, and the request includes data indicative of a destination endpoint. The network device compares the data indicative of the destination endpoint to the list of approved destination endpoints. If there is a match, the request is forwarded to a next hop router. If there is no match the request is dropped or returned to the guest device. | 01-03-2013 |
20130065637 | WIRELESS CELL PHONE HEADSET RELAY - In example embodiment, a BLUETOOTH application on a cell phone acts as an audio proxy and enables shared use of the cell phone's BLUETOOTH headset between the cell phone and a BLUETOOTH enabled desk phone. When a telephone communication is established via the desk phone, audio data is sent from the desk phone to the cell phone, and the cell phone relays the audio data to the headset. Audio data from the headset is relayed by the cell phone to the desk phone. | 03-14-2013 |
20130268981 | OPTIMIZATION OF VIDEO FOR WIRELESS DELIVERY - In one embodiment, a method includes receiving at a network device interposed in a network path between a source and a receiver, video optimized for a wired network link located between the source and the network device, identifying the receiver as a wireless device, optimizing the video for wireless transmission, and transmitting the video optimized for wireless transmission to the receiver. An apparatus is also disclosed. | 10-10-2013 |
20150222760 | METHOD AND APPARATUS FOR PROVIDING RINGING TIMEOUT DISCONNECT SUPERVISION IN REMOTE TELEPHONE EXTENSIONS USING VOICE OVER PACKET-DATA-NETWORK SYSTEMS (VOPS) - A Multiservice Access Concentrator (MAC) provides a time limit for a first ringing voltage signal in response to an attempted call. The call is attempted via a voice over packet-data-network system (VOPS), wherein the VOPS comprises voice over Internet Protocol (IP), voice over Frame Relay, voice over Asynchronous Transfer Mode (ATM), and voice over High-level Data Link Control (HDLC) network systems. Generation of the first ringing voltage signal is terminated upon expiration of the time limit. A control message is transmitted to terminate the attempted call, wherein the control message is transmitted via the VOPS. | 08-06-2015 |
