Call quality issues - what to check first

Troubleshooting Poor Call Quality

Most VoIP quality issues are caused by the internet connection, not the phone system itself. Run through this checklist before raising a ticket:

1. Test your internet speed - visit fast.com. You need at least 5 Mbps download and upload per active call.
2. Use a wired connection - WiFi introduces latency and packet loss. Connect via ethernet cable if possible.
3. Restart your router - unplug it for 30 seconds and reconnect.
4. Check for background downloads - large downloads or streaming on the same network can degrade call quality.
5. Check the time - peak hours (8am-10am and 12pm-2pm) can cause congestion on some ISPs.

If the issue persists, open a ticket under the VoIP & Telephony department with your diagnostics.
