Overview:

Dialogic’s PowerMedia XMS is a highly scalable, software-only media server that enables standards-based, realtime multimedia communications solutions for IMS, MRF, Enterprise, and WebRTC applications on premise or in the cloud. Built on 15+ years of software media processing experience, PowerMedia XMS is trusted by world-class service providers and large enterprises to power millions of rich media sessions.

With an extensive list of successful implementations that include MRF for VoLTE, carrier hosted contact centers, enterprise communications, voice messaging and “mission critical” next-generation 911 services, PowerMedia XMS has proven to be a key building block to new and innovative applications. When deployed with the optional Dialogic PowerMedia Media Resource Broker (MRB), PowerMedia XMS scales to meet growing service-provider and business requirements.

PowerMedia XMS allows for rapid integration and development through open, and industry standard APIs, including MSML, VXML, NetAnn, and JSR 309, plus a Dialogic RESTful API. As a 100% software solution with Network Function Virtualization (NFV), PowerMedia XMS allows for installation on commercial off-the-shelf (COTS) servers, virtual machines, or public & private clouds.

PowerMedia XMS supports an extensive range of real-time media processing needs, including:

  • Multi-party conferencing – low-latency mixing of audio and video, including HD voice and high-resolution video up to HD 720p, and Multi-point Control Unit (MCU) for group communications with the ability to adapt individual streams to optimize the experience for each user
  • Transcoding – any-to-any audio and video codec conversion for a wide-range of fixed, wireless, and web-oriented codecs, including transrating and transizing for video
  • Media interworking – conversion of underlying transport protocols and encryption interworking, including support for a WebRTC Media Gateway
  • Recording – flexible centralized audio and video recording for mixed conferences, or individual streams
  • Stream processing – analyze, insert, and modify the audio or video stream for speech recognition, DTMF, video overlays, and much more
  • Person-to-Machine – connect to computer-controlled interfaces, not just other people, for applications such as Interactive Voice (and Video) Response (IVR and IVVR) systems, and speech interaction

Features and Benefits:


Features Benefits
Highly scalable, software media server with advanced multimedia processing functionality with an optional PowerMedia Media Resource Broker (MRB) Facilitates the development and deployment of rich communication applications and services across Web, VoIP/SIP, Mobile and PSTN networks with a wide range of connected endpoints. By offloading difficult media handling requirements to PowerMedia XMS, service providers, and developers are able to focus on unique aspects of their application without the burden and cost associated with developing highly-scalable media expertise in-house.
Standards-compliant IMS MRF with full Voice over LTE (IR.92) and Video over LTE (IR.94) support Conforming to the 3GPP IMS architectural specifications, PowerMedia XMS can be deployed as a Media Resource Function (MRF), providing key media processing capabilities that may be required by IMS-based services such as VoLTE and RCS. Additionally, its conformance to IMS specifications promotes compatibility between legacy telephony networks and evolving IP telecommunication standards.
Robust HD audio and video media support with IETF, 3GPP and W3C WebRTC codecs As new codecs are being introduced into the market, PowerMedia XMS can act as a transcoding gateway, providing interworking of a wide variety of audio and video codecs. PowerMedia XMS’s software nature also means that new codec support can be rapidly added without changing physical DSPs or necessitating complicated firmware upgrades.
Support for Commercial-Off-The-Shelf (COTS), virtualization, and Network Function Virtualization (NFV) deployment models Reduces both OPEX and CAPEX by utilizing existing datacenter infrastructure and cloud services for deployment of dynamically scalable communication solutions.
Media control through open, and industry standards based API’s Energizes service provider and communication developers by leveraging industry-standard programmable APIs to rapidly add sophisticated media handling capabilities to their applications.
Web-based GUI and HTTP RESTful Management interface for media server management, control and monitoring Intuitive, yet powerful operator console can reduce OPEX when deploying solutions by enabling the quick resolution of operation issues. The HTTP RESTful web management interface provides seamless integration with existing infrastructure for real-time monitoring, alarms, logging, and tracing.
Scalable licensing from ten ports to thousands of ports per server The simple, flexible, and scalable licensing model allows paying only for the functionality your application needs and only when you need it. Applications can start with licenses for basic audio services and can later add HD voice or video capabilities when required by the application, thus providing significant CAPEX savings opportunities by allowing solutions to be scaled easily by software upgrade as demand grows.
