PowerMedia XMS

Rich Media Processing and WebRTC

for Developers and Operators.

What is server-side WebRTC media processing?

PowerMedia XMS serves the needs of application developers and network operators with:

  • Cloud-ready, virtualized media processing software
  • Production-ready media server interfaces for web and traditional media applications
  • A full suite of media application capabilities with WebRTC support
  • Comprehensive audio, video, and contact center features

Offloading difficult media handling to PowerMedia’s flexible rich media processing software helps to improve the user experience, optimize network efficiency, and reduce development time.


Typical Media Processing applications

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

  • Multi-party conferencing – low-latency mixing of audio and video, including HD, 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 – local audio and video recording or interface with 3rd party recording systems
  • Stream processing – analyze, insert, and modify the audio or video stream including 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) systems, speech interaction, biometrics, and more

PowerMedia XMS for Developers

Developers can leverage PowerMedia XMS’s programmable API’s to rapidly add sophisticated media handling capabilities to their applications. By offloading difficult media handling requirements to PowerMedia XMS’s specialized software, developers can focus on the unique aspect of their application without having to become media processing experts. PowerMedia XMS supports web-oriented APIs, a standardized Java interface, and media server scripting languages for easy development with powerful media controls.

PowerMedia XMS for Network Operators

Service providers and Network Operators can quickly plug PowerMedia XMS into their existing networks using its standardized media control interfaces. PowerMedia XMS is 100% software based and supports widely used hypervisors for easy integration into virtualized cloud environments. PowerMedia XMS is deployed in a variety of environments, including service providers, enterprises, and contact centers.

PowerMedia XMS for WebRTC

WebRTC is revolutionizing communications by providing a powerful and large open source community-based technology for embedding communications in web browsers and mobile applications. PowerMedia XMS includes support for WebRTC audio, video, and media plane, allowing developers and network operators to extend their applications and services to the web. PowerMedia’s web-oriented API’s and virtualized software are ideally suited for the dynamic, cloud-based environments where WebRTC is typically deployed alongside other web services.

PowerMedia XMS WebRTC Media Gateway

One of the most common WebRTC applications is extending existing SIP-based systems to communicate anywhere over the web. PowerMedia XMS acts as a WebRTC Media Gateway to mediate WebRTC media-plane differences from those of typical existing VoIP networks including encryption interworking, transcoding, and client-based NAT traversal support. PowerMedia XMS is pre-integrated with a variety of application servers and signaling gateways with HTTP-to-SIP (H2S) functionality and rapidly integrates with others using its web API or standard interfaces.

PowerMedia XMS Media Resource Function (MRF)

The 3GPP’s IMS architecture is the de facto specification for large scale telco networks and is a fundamental requirement for future federated communications services in that domain. PowerMedia XMS is conformant with 3GPP-specified media server interfaces. PowerMedia XMS provides critical media processing capabilities required by IMS-based services such as VoLTE and RCS. It simplifies and streamlines media processing management by consolidating disparate application-server based media processing into a centralized media server architecture as specified by the 3GPP.

Transcoding Gateway

New codecs are introduced into the network far faster than older ones are retired. 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 codecs support can rapidly be added without changing physical DSPs or complicated firmware upgrades.  PowerMedia XMS’s virtualization support also allows for much for flexible and cost effective cloud-oriented network models.

Data Sheet

  • Dialogic® PowerMedia™ XMS energizes application delivery by boosting performance with state of the art mixing of media-rich communications; software providing a seamless transition to virtualization and cloud delivery and telco hardened scalability.

Technology Brief

  • Dialogic’s WebRTC Codec Survey results are in! We targeted the survey at Dialogic’s developer community. Respondents included an equitable mix of developers from traditional service providers, established systems integrators, and newer upstarts.
  • Dialogic is pleased to present the results of its 2013 WebRTC Impact Survey that asked 169 key 
    executives of Service Providers and Application Developers to assess the impact of WebRTC on 
    their business models.
  • Delivering carrier class business communications services, such as Interactive Voice Response (IVR), for customer self-service and conferencing applications have become a profitable opportunity for service providers. Value added business communication services have proven to be a natural portfolio fit for service providers delivering core communications bandwidth and wide area networking services to large commercial accounts and government agencies. Thanks to the combined solution set of the Oracle Communications Converged Application Server paired with Dialogic® PowerMedia™ XMS, carriers and service providers can introduce value-added communication services, such as IVR self-service and conferencing solutions, to their portfolio in a cost effective and efficient manner.

White Paper

  • This white paper provides an introduction to HD Voice and discusses its current adoption rate and future potential, including use case examples which paint a picture that HD Voice upgrades to certain network and enterprise infrastructure will be seen as important, and perhaps as a necessity to many.

  • As the industry moves more towards full-scale IP networks, the issue of interconnecting diverse networks and different service providers - each with its own IP network(s) - becomes more important to resolve in order to support the seamless delivery of next generation services. There will be concerns for security and end-to-end quality of service (QoS) to be addressed to make sure the different “moving parts” that make up these services are delivered to the customer in the expected manner.  It will be important to set up the mechanism by which all the participants in the service delivery supply chain are compensated for the value they provide to the overall end-to-end service.

    The GSMA IP eXchange (IPX) provides a visionary approach to the challenges fixed and mobile service providers have with interworking IP-based services and networks. It provides multiple, service-aware connectivity models that provide QoS as well as cost efficient, optimal routing of IP traffic. The same platform can be extended to bridge the gap between IP and legacy TDM networks.
