VoIP Network Monitoring and Troubleshooting SolutionNIKSUN NetVoice is a powerful Voice-over-IP (VoIP) network management and security monitoring solution. NetVoice measures, records and reports on every VoIP flow in the network in real-time at production network traffic rates. It enables no-loss VoIP monitoring for enterprise and service provider networks. Its distributed and scalable architecture enables complete end-to-end monitoring in large-scale environments.

Integrated Voice and DataNIKSUN NetVoice together with NIKSUN NetVCR® provide the only comprehensive single integrated solution for monitoring VoIP and other data traffic simultaneously. This capability provides complete analysis of the interaction between VoIP and other data streams. Hence, a true measure of VoIP usage and QoS relative to other traffic can be precisely obtained. NetVoice provides all signalling, media and content information simultaneously.

Multi-Time Scale Analysis For 100% VisibilityNetVoice’s multi-time scale (packet to seconds to minutes to hours ...) and multi-level (link to application level) monitoring capability makes it an essential tool for VoIP network performance monitoring and troubleshooting. NetVoice provides 100% visibility into a VoIP network. It remotely captures network incidents the first time saving time and reducing costs for enterprises and service providers. QoS and StatisticsNetVoice provides the only unified turnkey solution for VoIP network management and offers detailed comprehensive decodes of most common VoIP protocols, QoS statistics (jitter, delay and packet loss) as well as audio/video playback to thoroughly ensure that the quality of every call is up to the mark.

NetVoice also includes quality metrics (for a call or a trunk) based on the ITU standard E-Model Mean Opinion Score (MOS) which takes into account codec & local-loop impairments as well as packet loss and jitter.

Interception Of Voice/Video and ReplayFor verifying voice quality or interception applications, NetVoice can record complete or filtered VoIP traffic at very high network rates. NetVoice is completely non-intrusive and does not affect other devices on the network or adds any overhead to the network that it is monitoring.

Collect, Record and Analyze Large Number of VoIP CallsNetVoice’s huge storage capacity, from gigabytes to multi-terabytes, enables users to store days, weeks to months and years worth of VoIP traffic. NetVoice’s scalable architecture is perfect for lawful interception, service assurance and compliance applications.

Traffic Analysis and VisualizationA powerful web-based user interface provides enormous flexibility in analyzing and visualizing calls through a network. The GUI has a easy to use layout for analysis based upon significant usability testing with enterprise and carrier customers.

Flexible Protocol, Traffic Analysis and CorrelationNetVoice supports multi-time scale analysis. NetVoice analyzes, filters and visualizes large amounts of data quickly and enables one to zoom in on only relevant data. With its support of advanced filtering, NetVoice easily enables one to locate information related to a specific calling number, called number, MOS score, etc.

At the microsecond and millisecond resolution, NIKSUN appliances detect and analyze short time events that are undetected when data is aggregated by the minute. Short-time events have been shown to have a major impact on the quality of audio and video transmissions.

NetVoice also provides detailed color enhanced protocol analysis information for OSI layers 2 to 7. It correlates call to message to packet analysis with an enhanced color-coding scheme.

Web-based User InterfaceNetVoice provides a Web-based interface (secure or standard) to en-able remote access from any computer using standard Web browsers such as Microsoft Internet Explorer and Netscape Communicator.

Powerful Analysis and Display FiltersNetVoice provides the capability for user-defined capture and display filters to quickly locate interesting and useful information. Filters can also be applied on retrieved data to display data related to a specific calling number, called number, etc.

Generate On-demand QoS and CDR InformationNetVoice generates QoS information (on a per call & a per trunk basis) & CDR data. Its large data store enables post-event troubleshooting on events that occurred hours, days or weeks earlier.

An Integrated and Scalable SolutionNetVoice can also be integrated with various other solutions from NIKSUN to provide complete network monitoring and troubleshooting for applications and services on an IP network.
