Top Quality Audio The Radisys media server supports a comprehensive Voice Quality Enhancement (VQE) feature set to overcome background noise, packet loss, acoustic echo and variable network delays, the four most common sources of audio quality problems in a VoIP network. This comprehensive VQE solution also generates VoIP quality metrics that can be used to support service level agreements. Reservationless and Meet-Me Conferences Subscribers can set up conference calls dynamically in reservationless mode acting as an "always on" meeting number or URI—or schedule a traditional Meet-Me conference call at a specific time. Subscriber PINs and Passwords allow easy, instant access to services. Economical reservationless conferencing services make up over 95 percent of the conferencing minutes of a modern CSP. Event Conferences The same SIPware platform also supports the Radisys Event Conference Manager (ECM), a sophisticated, PC-based conference management software program for operators conducting large- scale conferences. The software allows operators to easily provision and manage conferences, handle operator requests and participant arrivals, and assist participants during question-and-answer sessions for these premium audio conferencing services. Flyout windows enable operators to view information about conferences, participants, bells, prelists and requests all on one screen—eliminating the need to toggle between windows. Mobile Chair Person Using Radisys SIPware APIs, the Chinese CSP also developed an iPhone application, allowing a conference moderator to start and manage a conference call from a mobile smartphone device. Collaboration During working meetings, conference participants want to share and edit documents while on a call. To create this functionality, CSPs need to integrate enterprise customer environments and new business models. Designed with collaborative services in mind, SIPware's IP-based architecture facilitates integration with web-based GUIs, unified communications (UC) clients, web conferencing services, desktop calendaring and productivity tools, as well as existing network management and customer care systems. Moreover, SIPware provides detailed session records in the format required by the CSP's existing billing systems. Radisys Integrated Conferencing Solution Overview The Radisys Integrated Conferencing Solution consists of the SIPware Conferencing Application Server and Radisys Media Servers. SIPware hosts the signaling processing between endpoints and call processing logic, along with "controlling" the Radisys media server to perform the actual VoIP conference mixing between dozens—even hundreds of endpoints. Radisys SIPware can be combined with a Radisys software media server on a single commercial-off-the-shelf (COTS) service platform or scaled into large multi-site configurations supporting hundreds of thousands of ports. The distributed architecture tsports fault recovery without session disruption if any single solution component or geographic location might fail. SIPware also supports open IP-based APIs, allowing rapid integration with existing operations and administration systems, web-based applications and portals, along with integration with desktop productivity tools and unified communications systems. The Radisys SIPware conferencing platform is a complete, turnkey solution integrated with Radisys media servers.
