How to Fix Bad Call Quality

Common causes

• Insufficient bandwidth: slow or congested internet.
• Browser problems: outdated browser, too many tabs or conflicting extensions.
• Audio hardware: faulty headset, wrong input or output device.
• Network settings: VPNs, firewalls or Wi-Fi interference.

Check your internet connection

• Run a speed test. Voice calls need a stable connection with low latency and little jitter.
• Use a wired connection when possible, or move closer to your Wi-Fi router.
• Pause large downloads, uploads and video streaming during calls.

Optimize your browser

• Use the latest version of Chrome or another supported browser.
• Close unused tabs and disable extensions you don't need.
• Clear cache and reload the app.
• Make sure microphone access is allowed for the site.

Test your audio hardware

• Use a wired or good-quality headset instead of laptop speakers.
• Check that the right microphone and speaker are selected in your browser and computer settings.
• Try another headset to rule out hardware faults.

Adjust your network

• Turn off VPNs during calls.
• Ask your IT team to allow voice traffic (WebRTC) through the firewall.
• On busy networks, ask about Quality of Service (QoS) to prioritize voice.
