Did you lose a handset and receive a replacement?  You’re in the right place!

Did you add an extension and receive an additional handset?  You’ll want to go to Installing Your New PHONE PLUS Handset.

To make a replacement Yealink handset work with your current PHONE PLUS system, you will need to “de-register” the missing handset, then “register” your new handset with your Yealink cordless phone interface.

1. Gather all current Yealink handsets and look at the screens to determine which handset you are currently missing. Press the red hang up button once on each of your current handsets to identify which handsets you have remaining (ex: “Handset 1” or “Handset 2”).  You will need to de-register the missing handset.
2. On one of the existing Yealink handsets, press the middle OK button to open up the main menu.
3. From the menu, select Settings, the blue button with the gear icon.
4. Then select Registration.
5. Select De-Reg. Handset.
6. A prompt will come up asking you to enter a current PIN. Enter “0000” and click Done.
7. Select the handset that was lost, and press Ok to de-register.
8. Once the missing handset is de-registered, locate the Yealink cordless phone interface (pictured), and hold the wifi button down for ten seconds. The top green light will begin blinking.
9. Go to the main home screen of your handset and select the bottom left button that says Reg. This will register your new handset to the Yealink cordless phone interface (if the phone asks for a PIN number, enter 0000
10. Make test calls in and out to ensure the new phone(s) have been registered properly.

Repeat this process if you have multiple handsets to replace on your PHONE PLUS system.
