Troubleshooting Call Quality

Choppy audio, echo, or dropped calls almost always trace back to your network or device rather than the phone system itself. Work through these in order.

Check your network first

• Switch to a wired connection if possible — Wi-Fi is much more prone to the packet loss and instability that cause choppy audio.
• Restart your router/modem to clear up transient connectivity issues.
• Close bandwidth-heavy apps (video calls, large downloads, streaming) while you're on a call.
• Make sure you have at least 5 Mbps upload and download available.
• If you're on a corporate or restrictive network, confirm your firewall allows UDP ports 10000–20000 — calling traffic can be silently blocked by strict firewall rules.

Check your browser and device

• Use an up-to-date version of Chrome for the best compatibility with the web dialer.
• Update the mobile app to the latest version if you're calling from a phone.
• Disable browser extensions that might interfere with audio — test in an incognito/guest window to isolate the issue.
• Use a headset with a built-in microphone instead of your device's speaker/mic to cut down on echo.

If calls disconnect specifically in the mobile app

If calls consistently disconnect only when placed or received through the mobile app — but are fine on the web dialer — this usually points to an account-level configuration issue rather than something you can fix from your device. Contact support with details on when the disconnects happen (inbound/outbound, which number) so they can check your account's calling configuration.

Still having issues?

If problems persist after working through the above, contact support with the approximate time of the call, the number involved, and whether it was inbound or outbound — that lets them pull the specific call logs rather than troubleshooting blind.
