H5 does not transpose configuration changes.

[ALTGR SA]

Good morning,
I have configured some Fanvil H5 via (SBC) proxy phone.

The phones configure and work corretmante, but if I make configuration changes such as adding/removing/changing BLF the phones do not acknowledge the change.

If I do factory reset the configuration is received without any problems.

Does anyone have any ideas?

Reprovisioning doesn't work if you use 3CX certificates, but the H5 phones are not running the correct firmware.
