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.

Method, device, and system for providing a survivability gateway service

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.

Telecommunications system, method of managing a telecommunications system for optimized bandwidth usage during conference calls and program product therefor

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.

Method for tagging SIP contact headers while preserving the contact header format towards softswitches

A data management system with data stored in multiple disparate formats in synchronized stores, method of synchronizing the data and recovering from synchronization failures and program product therefor. Data changes in one data store are cached in a universal format in an active synchronizer and forwarded to a second store from the universal format cache. Standby synchronizers provide failover handling by identifying synchronization failures and self-selecting a replacement synchronizer to serve as the active synchronizer.

Data synchronizer with failover facility

A telecommunications system having a software dispatcher is provided for delivering messages between dispatcher clients, i.e., software subsystems that may be in the same process, a different process, or on a different machine. The dispatcher manages a pool of threads to balance the workload. The dispatcher can process both synchronous and asynchronous messages by dispatching the message to all registered subsystems in order of their registered priority.

Dispatching messages among registered software modules in telecommunications system including telephony internet server coupled between packet network and PBX

A method to ascertain a network topology, wherein a request message is transmitted from a first network node to at least one second network node connected to the first network node, a second network node enters its associated node number in the network into the request message and forwards the request message to at least one third network node connected to the second network node, the request message is forwarded until all the network nodes arranged in the network and all connecting lines connecting the network nodes have been passed through, the request message is transmitted back to the first network node, and the network topology information, available in the form of the node numbers entered in the request message, is stored.
