Abstract: A system, method, and computer program product for managing database servers and services is disclosed, which expands the capabilities of existing systems by providing better scalability and security. A database management system includes databases consisting of database clients and servers that handle the storing of information, a multi-database client that manages database servers, service modules which allow other systems to access the database servers, and a database access manager that manages requests from the service modules. A database access manager facilitates and coordinates interaction between the service modules and the multi-database client. Service modules provide interfaces from which other external or internal systems can access the managed databases. Requests can be sent between systems and the database access manager via the service modules. Two present and representative implementations of service modules are: user management and call detail record (CDR) collection.

Abstract: A method, system and computer program product are provided that reduce voice and data over IP (VoIP) packet overhead in an Internet telephony system, and regenerate missing or damaged data in a data packet. A media framer aggregates packets from multiple concurrent calls from several channels into a larger data packet. A transmission control module defines the format for each data packet, and updates and synchronizes header information in the data packets. A single virtual connection transmits data packets and other signals between originating and destination gateways located in the service areas for a caller and called party. System redundancy improves the quality of service by regenerating missing or damaged data in the data packets.

Abstract: A method, system and computer program product for route checking and management is described herein. In a voice over internet protocol environment, the invention allows for the testing of routes among various gateways. In one embodiment, gateways include routing managers for checking and storing route information. The method of the invention includes checking candidate routes for the level of quality, location and cost levels. Further, users can prioritize routes based on these criteria.

Abstract: A method, system, and computer program product that provides voice over the Internet communication. A Voice over the Internet (VoIP) system includes a gateway server that handles calls received from a public switched telephone network and a packet-switched network, a routing server, and a database server. Messages can be sent between the gateway server, routing server, and database server over the packet-switched network. A provisioning system is coupled to the database server. A management system is also coupled to the gateway server, routing server, database server, and management system over the packet-switched network. A network manager automatically queries a client database to determine an update, and sends a message representative of the update to at least one of the gateway server, routing server, database server, and management system over the packet-switched network. A licensing server supports licensing of the VoIP system.

Abstract: A method, system and computer software product for managing jitter buffering that accurately measures network latency, the variation in latency (also known as jitter), and efficiently manages the media packet stream and jitter buffers is disclosed. A framer time-stamps incoming packets. A traffic analyzer maintains a sliding window of statistics generated from a recent set of packets. A jitter manager monitors packets, receives and makes adjustments based on information received from the traffic analyzer, and manages any connected jitter buffers.

Abstract: A system, method, computer program product system for providing a carrier exchange (CX) backbone to a plurality of IP carriers to pass on their over-flow traffic to another participating carrier. The system and method offers a quality-based voice over Internet Protocol (VoIP) call routing management system with centralized call accounting. The system and method connects potentially incompatible IP networks (e.g., ATM, Frame Relay, etc.) to a single backbone operated by a CX provider. The barter-like system and method is mutually beneficial to all participants by providing low cost to originating gateways and additional revenue for terminating gateways in the form of increased minutes.
