In a bid to help organizations assess how well VoIP systems are delivering end-user services and identify the network causes of quality issues, NetQoS (News - Alert) Inc. has introduced NetQoS VoIP Monitor. NetQoS VoIP Monitor is a network-based VoIP solution that combines quality of experience with network performance to accelerate troubleshooting, without server agents or probes.

 

NetQoS VoIP Monitor functions in association with Cisco (News - Alert) IP Telephony systems running Cisco Unified CallManager 4.2. The system analyzes two of the most essential 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).

 

NetQoS VoIP Monitor tracks actual end user call quality to provide alerts on call performance issues and separate the cause of VoIP problems to the network source to help organizations to improve performance with faster troubleshooting.

 

“Monitoring VoIP performance without measuring actual call quality is like cooking without tasting the food. NetQoS VoIP Monitor focuses on the VoIP application itself, enabling IT personnel to understand call quality and connect it to the network impairments that may be causing issues,” said Jim McQuaid, senior product manager for NetQoS. “Combined with the existing VoIP capabilities of the NetQoS Performance Center, which includes end-to-end performance monitoring, traffic analysis, and device performance management with IP SLA reporting, NetQoS now has a powerful solution for ensuring optimal network and application performance before, during, and after VoIP implementation.”

 

NetQoS VoIP Monitor enables centralized monitoring of signaling flows producing key metrics, such as time to dial tone. It offers summary call quality data for all calls in the system, including calls using any PSTN gateway. Coupled with NetQoS Performance Center, it provides a single web-based console for managing converged networks.

 

The solution monitors the in-progress quality of all calls from selected phones for immediate analysis as well as offers safeguards to avoid false alarms, such as alerts only when call performance problems affect a designated minimum number of call minutes or calls.

 

Thanks to NetQoS VoIP Monitor integration, the NetQoS Performance Center now offers a comprehensive solution for managing an enterprise VoIP system along with all other business-critical applications. The NetQoS Performance Center now helps users measure response times to show the impact of VoIP on existing applications, determine the volume of VoIP traffic across the WAN, perform active VoIP testing/monitoring via Cisco IP SLA to measure, VoIP jitter, latency, and packet loss, get hold of metrics on call signaling/setup protocols and most importantly, evaluate the quality of voice calls.
