| NetQoS Launches NetQoS VoIP Monitor NetQoS has launched NetQoS VoIP Monitor to help organisations gauge how well VoIP systems are delivering end-user services and pinpoint the network causes of quality issues. By adding call setup and call quality metrics to its existing VoIP management capabilities within the NetQoS Performance Center, NetQoS now offers a comprehensive performance monitoring solution for converged networks. NetQoS VoIP Monitor is a network-based VoIP solution that links quality of experience to network performance to speed troubleshooting, without server agents or probes. The product, working with Cisco IP Telephony systems running Cisco Unified CallManager 4.2 or later, provides insight into two of the most important components of VoIP quality: call setup operations (such as time to dial tone and post-dial delay) and audio quality (MOS and underlying network impairments). By tracking actual end user call quality, providing alerts on call performance issues, and isolating the cause of VoIP problems to the network source, NetQoS VoIP Monitor enables organisations to improve performance with faster troubleshooting. With the addition of NetQoS VoIP Monitor, the NetQoS Performance Center now provides a complete solution for managing an enterprise VoIP system alongside all other business-critical applications by enabling IT professionals to: • Measure response times to show the impact of VoIP on existing applications; • Determine the volume of VoIP traffic across the WAN – including who is using it and when – to ensure VoIP traffic is not starving out other business-critical applications; • Monitor the health and availability of VoIP devices; • Perform active VoIP testing/monitoring via Cisco IP SLA to measure VoIP jitter, latency, and packet loss; • Obtain metrics on call signalling/setup protocols; • Gauge the quality of voice calls. Specific NetQoS VoIP Monitor Features: • Passive, centralised monitoring of signalling flows producing key metrics, such as time to dial tone. • Summary call quality data for all calls in the system, including calls using any PSTN gateway. • Integration with the NetQoS Performance Center to provide a single web-based console for managing converged networks. • Real-time call watch monitors the in-progress quality of all calls from selected phones for immediate analysis. • Safeguards to avoid false alarms, such as alerts only when call performance problems affect a designated minimum number of call minutes or calls. • Operations and Network Engineer views into call quality data, with separate Administrator views for configuration. • Ability to scale to monitor large numbers of phones for enterprise VoIP deployments. • Available as a single standalone unit or in a distributed configuration (up to ten individual Collectors and a single Management Console unit). write your comments about the article :: © 2007 Computing News :: home page |
