If your desk phone or conference unit is acting up, sometimes the quickest fix is to start fresh. Knowing how to factory reset a Yealink phone ensures you can clear old settings, restore the default password, and get the device back online quickly.
Whether you’re troubleshooting a T5 series desk phone, a DECT base, or a CP conference model, this guide walks you through every reset method step by step—so you can get your Yealink device working like new in minutes.
TLDR: Factory Reset a Yealink Phone
With the phone idle, press and hold OK for 5 to 10 seconds.
When “Reset to factory settings?” appears, press OK to confirm.
The phone reboots and returns to defaults.
Model notes:
Before you reset
A factory reset clears user data and settings, and resets the admin password to its default value. It does not typically roll back firmware, but a provisioning server may reapply firmware or config during first boot. (Yealink Support)
If the phone is managed by your provider, ask them first so it can auto‑provision after reboot.
Factory reset by model family
The screens and keys vary a bit by model. Use the method for your series below.
Most Yealink T2/T3/T4/T5 desk phones
Method A — long‑press key: With the phone idle, press and hold OK for 5–10 seconds, then confirm. (RingCentral Support)
Method B — menu path: Menu → Advanced → Reset Config → Reset to Factory Settings → OK. Default admin password is admin unless changed. (Zoom Support)
Yealink T56/T57/T58/VP59 and similar T5x

Yealink CP conference phones
CP925/CP960/CP965: Long‑press the Home button for ~20 seconds, then confirm. (3CX)
Reset a Yealink DECT base and handset

Unplug power or PoE.
Press and hold the Paging/Connect button on the base.
While holding, plug power or PoE back in.

Reset the base from a handset
On a registered handset: OK → Settings → System Settings → Base Reset. Enter PIN 0000 if unchanged, confirm reset. (SimpleVoIP)
Yealink’s DECT guidance also documents long‑pressing the device button to trigger a factory reset. (Yealink Support)
Factory reset from the web interface
If you can log into the phone’s web UI as admin:
Find the IP address, then browse to it.
Log in as admin / admin unless changed.
Go to Settings → Upgrade → Reset to Factory and confirm. (Zoom Support)
After the reset: get back online fast
Find the phone’s IP address
On most desk phones, press OK to open Status and read IPv4.
On DECT, OK → Status → Base to view the base IP. (Yealink Support)
Sign in to the web UI with admin credentials and confirm network settings.
Auto‑provision
If the provisioning server is already set, trigger it: Settings → Auto Provision → Auto Provision Now, or enable Repeatedly and set an interval. (Yealink Support)
Change the provisioning server manually
You can set the provisioning URL in the phone and then force a pull.
Option A — via web UI
Browse to the phone’s IP and log in as admin.
Go to Settings → Auto Provision.
In Server URL, paste the provisioning URL your provider gave you.
If your provider uses authentication, fill User Name and Password.
Click Confirm, then Auto Provision Now to apply. (Yealink Support)
Option B — from the phone screen
Menu → Advanced → Auto Provision → set Server URL → Confirm, then run Auto Provision Now. Wording varies slightly by model. (Zoom Support)
Tip for larger rollouts: Yealink also supports RPS and DHCP options for zero‑touch setup. Your provider can add the MAC in Yealink’s Device Management Service or deliver the URL with DHCP Option 66. (Yealink Support)
Two popular Yealink how‑tos
1) Find your Yealink phone’s IP address
Desk phones: press OK to show Status and read IPv4.

2) Program BLF or speed‑dial keys
In the Web UI → Phone → DSS Key, set a line key to BLF to monitor an extension, or Speed Dial for a quick call. BLF LEDs reflect idle, busy, and ringing states. (Yealink Support)

Troubleshooting and FAQs: How to Factory Reset a Yealink Phone
My phone asks for an admin password to reset. What now?
Try the Redial long‑press method on T57W/T58 series. It can trigger a reset without entering the password. If that is disabled by policy, contact your provider to unlock or reset credentials. (GoTo Support)
Will a factory reset change my firmware version?
A reset clears config and data, not the installed firmware. However, if your provisioning server enforces a specific firmware, the phone may immediately upgrade or downgrade after it re‑provisions. (Yealink Support)
The phone is stuck or bricked after a failed update.
Use Yealink’s TFTP recovery process to reflash firmware, then provision again. (888VoIP Support)
Default passwords and pins
Web UI default admin password is admin if unchanged. DECT base default PIN is 0000 unless changed. (Zoom Support)
