SolarWinds VNQM offers a scalable VoIP monitoring solution that tracks Cisco CallManager and Avaya Communication and Media Server performance. After you have added your call manager devices to SolarWinds VNQM and configured them to send call data to SolarWinds VNQM, SolarWinds VNQM presents current network performance metrics and different aspects of your VoIP infrastructure in views that contain tables, graphs, and charts. You can use the SolarWinds VNQM dashboard view to drill in to problem areas to start identifying the underlying problems.
In this VoIP troubleshooting scenario, an employee has called you (the VoIP engineer) complaining of a call that dropped earlier in the day. To head off other complaints, you decide to be proactive and use SolarWinds VNQM to identify the cause of the issue.
Before you begin:
The following example shows you how to use SolarWinds VNQM to look up the record of the dropped call and identify the source of the problem.
In this example, the search includes all calls that failed within the last 2 hours.
In this example, the USAUS-AVAYA-ACM-01 device managed the call.
While the MOS and packet loss at the call origin are acceptable, the latency and jitter values are high. For the call destination, all quality metrics are too high, especially the 39% packet loss.
This resource shows that jitter and latency between hop 1 and hop 2 are too high. In addition, the network segment between router 2 and router 5 is not meeting its SLA.
From here you can:
