Troubleshoot Avaya VoIP Call Quality With VoIP and Network Quality Manager

Troubleshooting Avaya VoIP call quality can be complicated. VNQM will help you:

  1. Identify the cause of jitter

    Jitter can occur due to congestion in the LAN or the access link, load sharing, routing table updates, and route flapping.

  2. Reduce latency on the call

    Latency can occur as a result of propagation delay, handling delay, queuing delay, router outages, or link congestion.

  3. Recognize packet loss quickly

    Packet loss due to link failures, traffic congestion and buffer overflow, faulty networking hardware, or a misrouted packet.


1 Search and filter your call detail records (CDRs)

1 Search and filter your call detail records (CDRs)

Easily search and filter your CDRs and call management records (CMRs) to isolate the affected call. Search criteria includes Call Origination and Destination (phone number, IP address, region, gateway/endpoint), Call Manager, Call Time, Call Status, and Call Quality. Search for all calls within the last 15 minutes with a critical MOS score then select the appropriate call to view call details and begin troubleshooting.

2 View VoIP Call Details

View the specific call details including the VoIP Call Signaling, the Call Path Details, and the corresponding IP SLA Operation. In the example below, MOS score, jitter, latency, and packet loss for the call are high. You can correlate with HOP 1, 2, and 3 of the SLA Operation path. By clicking on the IP address of HOP 1, 2, and 3, you will be presented with IP SLA operation details to begin troubleshooting potential network issues.

3 Correlate with IP SLA Operation

3 Correlate with IP SLA Operation

Call paths can then be correlated to an IP SLA operation path where you can view RTT, jitter, and latency.

4 Correlate to Network Device Performance

4 Correlate to Network Device Performance

With integrated SolarWinds Network Performance Monitor (NPM), you can view detailed performance metrics such as CPU and memory utilization, interface status and utilization, latency, and response time of the IP SLA source device for further troubleshooting.
