BLF buttons are not updating

[Jlidds]

I have a number of clients that have found BLFs are not updating on Fanvil handsets (X3U, X4U-v2, X6U, X210, V62G). Even after reprovisioning the phone and power cycling the phone, the BLFs are not updating to reflect the user within 3CX.
We factory reset a couple of these but now they do not show any BLFs at all. This appears to be happening on both V20 and V18.

Has anyone come across this recently? It was only picked up at the end of August 2025.

Hello Jlidds,

In short this means that provisioning does not work anymore for the Fanvil phones.
This could be some problem with the provisioning template.

You could execute the following test:
Login to the 3CX Admin - User account - IP Phone ->> copy details to build a link
{provisioning link} / {mac adres} .cfg

This should download a config file for the phone, if not, than the provisioning template is not good.
If this is the case, copy MAC, and delete phone from user, than add the phone again with same MAC.

Redo the test above, or just reboot the phone to check if it does now get the provisioning config again.
