We have several Fanvil X210's cloud PBX that do not load BLF's loaded in portal...

We program BLF's in 3CX' Users' phone configuration but they do not load on phone. Even when we manually program BLF's on Fanvil, these disappear when we update phones.

Hi @David Adame

How are the phones provisioned? Local,remote, STUN or SBC? Also what is your PBX version and what firmware are the phones running?
When you manually add BLF's to phones and you restart / reprovision them those are overwritten by the default configuration.

Hi,

Thanks for the reply.

We are not using an SBC, registration is through STUN remote and our PBX runs on 16.0.655. Th phone is a Fanvil x210 on 1.12.19 and we've tried forcing the phone to manually accept the BLF programming, but somehow this phone loses it when it updates.

Product	Professional Annual
Version Number	16.0.655

Phone is on 1.12.19

Hi David,

At the site where the X210 is is installed, can you confirm that

- There is no SIP ALG on the firewall
- The SIP port and RTP ports are forwarded on the firewall for that specific phone's IP
- The phone has been reset and and reprovisioned automatically (not manually) using the Fanvil guides
