Dialogic® PowerMedia™ Extended Media Server (PowerMedia XMS) is a powerful software media server that enables standards-based, real-time multimedia communications solutions for mobile and broadband environments.
PowerMedia XMS can help reduce development and operational costs by offering standards-based media control interfaces and management capabilities that can be deployed in the cloud or in traditional environments, such as the IP Multimedia Subsystem (IMS).
PowerMedia XMS is built on robust, feature-rich, and award-winning host media processing technology that has been developed by Dialogic and deployed by customers worldwide for more than a decade.
Overview
PowerMedia XMS offers a rich variety of advanced media processing functions, including audio and video play/record and content streaming, and can be used to build a wide variety of real-time multimedia processing solutions. These solutions can range from traditional voice messaging and conferencing to innovative video conferencing and social interaction applications, such as delivering internet content into a video conference in real time using the RTSP protocol.
Deployment Environments
PowerMedia XMS can be deployed on premise or in the cloud, allowing enterprise and service provider customers to benefit from cloud deployment. The control interfaces offered with XMS provide developers with the following choices of deployment environments:
Traditional SIP — A SIP Application Server (AS) controls XMS using the MSML control interface (RFC 5707) to enable deployment as an IMS Media Resource Function (MRF)
Innovative Web 2.0 and Cloud — A web application written in an appropriate language (Python, JavaScript, etc.) can control XMS using an HTTP RESTful interface. Developers can use SIP call processing functionality built into XMS or a third-party call control model where SIP signaling is handled by an AS.
Operations, Administration, and Maintenance
PowerMedia XMS provides powerful and user-friendly OA&M functionality, and can generally be installed and configured for initial use in 30 minutes or less. In order to reduce operational costs when deploying solutions, XMS can be managed remotely through a web-based operator console and an HTTP RESTful interface. XMS also supports remote real-time monitoring, alarms, logging, and tracing.
Licensing
The simple, flexible, and scalable licensing model of PowerMedia XMS lets customers pay only for the functionality they need when they need it. XMS-based solutions can be scaled from ten to thousands of ports by simple software upgrade.
