View Support Downloads for this product
The Radisys Software Media Server is designed to install and operate on Linux-based COTS hardware servers, for enterprise and IMS MRF audio/video media processing applications.
The Radisys Software Media Server is a Linux-based SIP media server for enterprise and IMS audio/video media processing applications.
Carrier-Class features in a Software Product Offering
Radisys has built a reputation as the global leader in carrier-class media processing with our existing IP media server hardware products. The Software Media Server extends Radisys media processing technology into a flexible software-only product, providing enterprise VoIP and IMS solution vendors with additional platform and deployment options.
Reduce Total Cost of Ownership
The Radisys Software Media Server consolidates the functions of traditional announcement and recording servers, audio and video conference bridges, interactive voice response units (IVR/VRU), messaging equipment and speech platforms onto a single media processing platform which lowers the total cost of ownership in your IP telephony data center.
Economical media processing for Enterprise VoIP Applications
A single entry-level Radisys Software Media Server deployment can economically support a broad range of Enterprise VoIP applications including IP PBX, IP Contact Centers, VoiceXML-based IVR, Unified Messaging, or voice/video enterprise-wide conferencing.
Powerful enough for large IMS multimedia deployments
Radisys Software Media Server can be easily scaled through additional Linux-based compute platforms to deliver an optimized Multimedia Resource Function (MRF) for many of the most demanding IMS multimedia processing applications including video ringback tones, mobile video conferencing, calling card, IP Centrex, or network gaming.
Multiple Hardware Platform Options, including ATCA
Radisys Software Media Server, running on a carrier-grade Red Hat Linux operating system, can be deployed on commercial-off-the-shelf Linux appliance or blade servers, as well as AdvancedTCA platforms such as the Radisys Promentum Compute Modules.
Based on eXMP™ Media Processing Technology
The Radisys Software Media Server utilizes Radisys' new eXMP™ technology, a cross-platform media processing technology which is at the heart of all Radisys media processing products. eXMP technology maximizes media processing capacity and controls task distribution to increase computing resource efficiency. Based on Linux, eXMP technology also provides improved security and management features.
Interface Compatibility with any Radisys Media Sever Product
Since all Radisys media processing products are based on eXMP, the Radisys Software Media Server includes the exact same SIP control interface, management, and media processing feature behavior as our market-leading Radisys hardware-based IP media servers. Existing Radisys customers and solution partners can efficiently certify the Radisys Software Media Server with their solutions, while new Radisys Software Media Server customers can easily scale their integration development onto alternative Radisys media server platforms in the future.
