This adoption of UC services to enable better collaboration assumes to enable IT Staff to interrogate by that service quality will be sufficient for end users to interact effectively. Today’s UC extension, phone number, user ID deployments, however, are very complex, require uncompromising interoperability or IP address between multi-vendor products and traverse a number of different network domains. While • Leverages nGenius Infi niStream traditional performance monitoring approaches have focused on the network-related appliance as a common intelligent performance of these services, there are a myriad of issues that can impair video and data source for analyzing and voice quality. IT organizations must assess the performance of all components involved in generating performance metrics for the call across the entire network from end-point to end-point which includes call signaling voice, video and data applications and evaluate call quality from the perspective of the user. To achieve a true representation of voice and video quality, IT organizations must look inside the packet payload and • Deploy standalone or integrate with analyze the media waveform to understand how echo, signal-to-noise ratio, and other nGeniusONE platform environmental artifacts are affecting the end-user quality of experience in addition to the network affects such as latency, jitter and packet loss. Product Overview nGenius® Voice | Video Manager is a UC performance management and analysis solution that enables comprehensive real-time service management for UC services. It can be deployed as a standalone UC Performance management solution or in conjuction with the nGeniusONE™ unifi ed performance management platform for comprehensive service delivery management capabilities encompassing voice, video and data services. nGenius Voice | Video Manager delivers granular application-specific metrics for IP- based Telepresence, Video and Voice session transmission and conversation quality to characterize real-time service performance and the true user experience.
