Fanvil X3 stops talking to the PBX via SBC

[AGidi]

Hello guys, we have an odd situation. We deployed around 25 fanvils X3 on 5 remotes stores.

Some of them, any given morning, stop working. More phones on the same SBC continue to work. Just one or two a month stop talking to the PBX.

We have a pi based SBC on each site, we load the www console, go to Lines APPLY settings and it goes back to work.
We have not been able to reproduce or diagnose why.

Any ideas? suggestions all welcomed.

I've had the same behavior with X3's on my hosted platform although it's gotten better after a firmware update so I don't think the SBC is a factor. Are you running the current firmware and 3CX templates?

I am not sure if related (as I do not use Fanvil) but there were some registration-like issues I recall recently where registration simply bombed out over time - here are some links for reference if you would like to look:

The links may help for ideas anyway.
