20080219265 | Method for tagging SIP contact headers while preserving the contact header format towards softswitches - A private communications network and method of managing calls in a private communications network. A Session Border Controller (SBC) listens for private network voice communications originating from private communications devices, e.g., Session Initiation Protocol (SIP) devices sending/receiving Voice over Internet Protocol (VoIP) communications such as SIP messages. The SBC assigns a unique port to each registering communications device and adds a path header with a single, common SBC port to the SIP register messages. A softswitch responds by adding a route header to identified voice communications. Thereafter, all identified voice communications pass through a single, common SBC port. | 09-11-2008 |
20090122791 | METHOD AND APPARATUS FOR SELECTIVE RECOVERY FROM BRANCH ISOLATION IN VERY LARGE VOIP NETWORKS - A digital telecommunications system, a method of reconnecting branches to a softswitch in a communications network and a program product for reconnecting branches to a softswitch in a communications network. A softswitch manages communications between devices at network endpoints, e.g., session initiation protocol (SIP) devices. When a branch is disconnected from the softswitch, the softswitch manages reconnects, prioritizing reconnects when multiple branches request reconnecting. | 05-14-2009 |
20090245497 | Telecommunications system, method of managing a telecommunications system for optimized bandwidth usage during conference calls and program product therefor - A telecommunications system, method of managing a telecommunications system and program product therefore. Telecommunications system branches are linked to a network and to each other in a wide area network (WAN). Each branch includes telecommunications devices and a media processor that supports a concurrent port for each local telecommunications device. A controller, e.g., at a data center, selects media processing resources to aggregate system media during conference calls for efficient bandwidth use. The controller may select resources based on user location, Call Admission Control (CAC) policy bandwidth usage, and availability of media resources and media processor ports. | 10-01-2009 |
20130066960 | Apparatus and Mechanism for Dynamic Assignment of Survivability Services to Mobile Devices - A system, a method and a device are each configured for dynamic assignment of survivability services to communication devices (such as, e.g. tablets, smart phones, mobile phones, laptops or other types of mobile communication devices) based on the device's current location and network context. Survivability services provide session and service continuity in case a centralized or cloud based session management service that may be hosted by one or more remote computer devices, such as for example servers, is not reachable due to network failure or service failure. | 03-14-2013 |
20130198307 | Apparatus and Method for Subscription to a Service and Use of the Service - An apparatus and mechanism to subscribe to a single address and or session management service from multiple devices (such as e.g. tablets, smart phones, netbooks or other types of communication terminals or client devices) with a single account and password through the automatic assignment of a dynamic opaque SIP service profile to each device a user uses to signin to the service. After sign-in transparent call management services are provided to the user and allow the user to control sessions on any signed-in device from any signed-in device without revealing the distinct dynamic opaque SIP service profiles to the user. | 08-01-2013 |
20130212287 | Method and Apparatus for Controlling Sessions From One or More Devices - An apparatus and mechanism to manage multi-modal real-time or quasi real-time sessions such as voice, video, instant messaging, or web-conferencing across multiple devices through a simple subscription to a session management service. A user can subscribe to the service from many devices (e.g. mobile device, desk phone, personal computer, internet appliance, internet TV, communication terminal, etc.) and through the service seamlessly move sessions back and forth between subscribed devices. In a preferred embodiment, a user utilizes a “virtual slider” in a simple “two touch” procedure to effectuate the movement of a communication session from one device to another device via the service. | 08-15-2013 |
20130311618 | Method and Apparatus for High Performance Low Latency Real Time Notification Delivery - A method for real time notification delivery comprises providing to an application server event notifications directed to a plurality of user agents that are at a site remote from an application server and that receive event notifications through a first network device that is capable of receiving aggregated notification messages, aggregating a plurality of event notifications directed to a plurality of user agents to create an aggregated notification message directed to a first network device, and routing an aggregated notification message to a first network device via a communications network. | 11-21-2013 |
20140016455 | METHOD, DEVICE, AND SYSTEM FOR PROVIDING A SURVIVABILITY GATEWAY SERVICE - A method and apparatus dynamically pair a user's communication devices with a personal survivability gateway. The gateway can support the establishment of communication services in case of a network failure between a site where the user's communication devices are located and the site that provides the user's communication services. Preferably, the survivability gateway is configured so that if a network failure occurs, the user does not experience service degradation, or at least significant service degradation. For instance, the user's inbound and outbound communications during such an outage may be routed through his personal survivability gateway and a survivability proxy to limit, if not eliminate such service degradation. | 01-16-2014 |
