Step 2: Factory Reset the IP Phone

Before provisioning the IP phone, the phone must be brought back to factory defaults in case the device has

residual settings of a previous configuration. To reset the device read our How to Factory Reset Yealink IP

phones document.

Step 3: Provision the phone

There are several methods to provision a phone:

● Plug & Play - For phones on the local LAN or behind the 3CX SBC.

● RPS - For phones on remote networks that will connect directly to 3CX and use STUN.

For more information, see “When can I use which provisioning method?”

Local LAN or SBC: Provision via Plug’n’Play

1. Connect the phone to the network. A PnP request will be sent automatically to 3CX.

2. Go to the 3CX Management Console ⇒ “Phones” page. The new phone will be marked in Bold.

3. Click on the BOLD entry and choose between “Assign Ext” or “Add Ext”, depending on whether

you want to assign the phone to an existing extension or create a new one.

which network this IP phone is connected.

5. Click “OK”. The phone will configure automatically and will reboot to finalize the setup.

Remote phones: Provision via RPS server

1. Take note of the phone’s MAC address, usually written at the back.

3. From the dropdown list select the extension to which this phone must be assigned.

4. In the next dialog select the Vendor/Model of the phone and enter the device’s MAC address.

5. Switch the “Provisioning Method” to “Direct SIP (Stun - Remote)” and click “OK”.

from the dashboard:

If the message appears as a “Warning” follow the instructions outlined in the message and use the Manual

Link Provisioning method outlined here.

username, then press the DOWN arrow to get to the password input field and enter the voicemail pin as

the password.
