How to Initiate an Intensive 48-Hour Latency Test with Nextiva Clarity

How to initiate an Intensive 48-Hour Latency Test with Nextiva Clarity

Latency refers to a short delay (usually measured in milliseconds) between when an audio signal enters and when it exits a system. Latency can be caused by analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound through air. On a stable connection with sufficient bandwidth and minimal latency, VoIP systems typically have a minimum of 20ms inherent latency and target 150ms as a maximum latency.

An Intensive 48-Hour Latency Test in Nextiva Clarity is used to help diagnose connection issues that may not appear on normal 5-minute interval tests. It is recommended that this test be performed during peak business hours, and it will not cause any disruption or degradation in service.

Follow the steps below to initiate an Intensive 48-Hour Latency Test in your Nextiva Clarity device:

  1. Navigate to nextiva.mycloudconnection.com, log in using your credentials, and select the name of the site you are troubleshooting.
  2. In the navigation menu, expand the Diagnostics section and select Network Health.
  3. Scroll down to the bottom of the page and check Monitoring Active in the Intensive 48-Hour Latency Test tile (Figure 1-1).

  4. Click the Apply button to launch the test, which sends out 10 pings every 30 seconds for 48 hours.
  5. The results for the past 10 hours are displayed as a simple line graph. If you’d like more detailed information, click the More… button or just click on the results themselves.
  6. The detailed information is broken up into three different time scales. Each time scale displays the round trip times and packet loss. It also displays pings with lost packets in a graph. Each ping is represented by a dot, and the dot’s color reflects the number of lost packets. Please note, you won’t see any results right after you initiate the test.
