Jitter is the variation in the time between packets arriving, caused by network congestion, timing drift, or route changes. The longer packets take to arrive, usually affects audio. Jitter is measured in milliseconds(ms), if you are receiving Jitter greater than 50ms can increase latency and result in packet loss.
Jitter, Latency and Packet Loss can cause the following issues: Choppy audio, Delayed or Dropped calls, Static or Garbled audio.
What can you do to resolve these issues?
- Check to make sure your connection is stable.
Use a router recommended by Nextiva, proven to provide good QoS.Here is a list of recommend routers here.
Perform a Bandwidth test. Each phone has a 100kb upload and 100kb download requirement to work properly.
For Static, Echo, Garbled
- Look at the physical connection between the phone and ethernet cord.
- For handset devices, test if there is static when the call is on a speaker phone. If there is still static, the device may need to be replaced. Contact Nextiva sales for a replacement device.
- If the call was succesful with the speakerphone on, then the issue is likely the headset itself. Contact sales to receive a new headset.
