Troubleshooting
Common Issues & Fixes
Try these solutions before calling support.
No dial tone / phone won't register
Check that the Ethernet cable is firmly connected to the LAN port on the phone and the wall jack or switch. Verify the phone has power (screen should be lit). Try rebooting the phone by unplugging the Ethernet cable for 10 seconds and reconnecting. If the phone still shows 'No Service' or fails to register, contact Simple Fiber support — we may need to re-provision your phone.
Poor call quality / choppy audio
First, run a speed test at fast.com on a computer connected to the same network. If speeds are low, the issue may be your internet connection. Make sure the phone is connected via Ethernet (not WiFi) for best quality. Check that no one is running large downloads or uploads during calls. If the issue persists, contact us — we can prioritize voice traffic on your connection.
Can't hear the other party / one-way audio
Reboot the phone by unplugging the Ethernet cable for 10 seconds. Check that you're not on mute (mute icon on screen). If using a headset, make sure it's properly connected and the audio path is set to headset. If the problem continues, contact support — it may be a network or firewall issue.
Phone keeps rebooting or restarting
Check your Ethernet cable — a loose or damaged cable can cause power cycling on PoE phones. If using a power adapter, make sure it's the original Yealink adapter (third-party adapters can cause issues). If connected through a PoE switch, verify the switch provides enough power. Contact support if reboots continue.
Voicemail not working
Try dialing *97 directly to access voicemail. Make sure your voicemail PIN is set up (default is usually your extension number). If calls aren't going to voicemail, check your call forwarding and answering rules at talk.simplefiber.com. Contact support if you need your voicemail box reset.
