Initial Setup

  3. 3Once registered, you'll see your name and extension on the screen.

Connect to WiFi (Optional)

How To

Common Tasks

Step-by-step instructions for the most common phone operations.

1

Check & Set Up Voicemail

  1. 1Press the Message button on your phone, or dial 5001, then follow the voice prompts.
  2. 2The default voicemail PIN is 1234 — you'll be prompted to change it and record your greeting.
  3. 3Check voicemail remotely: call your own extension until it reaches voicemail, press the * key, then enter your PIN followed by the # key.
  4. 4Prefer the web? Log into talk.simplefiber.com and open the Messages tab to listen to, download, delete, or forward your messages.

Send Voicemail to Email

  1. 1Voicemails can be emailed to you so you can listen on your computer or smartphone.
  2. 2Turn it on in the portal at talk.simplefiber.com under Voicemail > Email Notification.
  3. 3We recommend the "Send w/ attachment, move to trash" option — it emails each voicemail and clears it off the phone so your mailbox doesn't fill up.

  3. 3To forward your company's MAIN number (not just your extension), log into the portal at talk.simplefiber.com — Manager permissions are required.

  3. 3To pick up: press that same Park key from any phone in the office.

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 SimpleFiber 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 5001 directly to reach your voicemail. Make sure your voicemail PIN is set (the default is 1234). If calls aren't going to voicemail, make sure call forwarding isn't on — dial *73 to disable it — or review your answering rules at talk.simplefiber.com. Contact support if you need your voicemail box reset.
