Step 1: Verify the Firmware on Your Fanvil F52/F52P, C58/C58P, C62/C62P IP phones
Important Note: Supported firmware version is v.2.3.431.247.
You’ll need to verify that the firmware version that’s currently installed on your Fanvil phone is v.2.3.431.247. To check which firmware is installed on your Fanvil phone, power up the phone and press “Menu” > “Status” and scroll down to “Firmware” so that you can see the version. 3CX Phone System users that have 3CX Maintenance Agreement can update their Fanvil firmware from within 3CX Phone System by logging into the 3CX Management Console. To do this, visit the Phones node and select your Fanvil phone and click on the “Upgrade Firmware” button. If you’re using an older, outdated version of 3CX Phone System, visit the Fanvil Support page and download the latest firmware for your Fanvil phone.
It might be required to factory reset your phone after a firmware update to ensure that any previous configuration is erased.
Step 2A: Provisioning a Fanvil F52/F52P, C58/C58P, C62/C62P IP Phones Using Plug and Play
To begin Plug and Play provisioning plug your Fanvil IP Phone into the same LAN subnet as the PBX and power it up. Make sure you’ve plugged your phone into the same LAN subnet as the machine that has 3CX installed on it (3CX Phone System must run on port 5060) and that the phone has been reset to factory settings. If you are trying to provision an extension in a remote network (WAN) in a different subnet, or on a PBX whose default port is not 5060 please skip this step and see Step 2B.
