Read how to check what firmware the phones are running on and how to upgrade them in this guide: How to manual upgrade a Fanvil IP phone.

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 Fanvil X and H series 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.
  • Manual Provisioning - 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.

  1. 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.

  1. All major provisioning settings are pre-populated. If your PBX has multiple network cards, select to which network this IP phone is connected.
  2. Click “OK”. The phone will configure automatically and will reboot to finalize the setup.

Remote phones: Provision with the Manual Provisioning Link

In order to provision the device for STUN (Teleworker) usage, you must use the Manual Link Provisioning method outlined here.

IP phones can be tweaked to match the user’s needs. Those might be skipped if they are not desired and the phone will be rolled out in a default configuration. Also they can be altered at a later stage and changes applied via the Management Console → Phones → Select Device → Re-Provision :
