FANVIL x series

[Federico Moschini]

Dear Support team,

Even if I received Upgrade Finished on the phone, after rebooting all the Fanvil phones have "SIP Register failed message".

If I restore the old firmware no problem.

Issue is with latest Firmware release and 3CX 15.5

Provision on stun.

Dear Support Team,

Any idea please? We cannot use 15.5 and we have to roll back if no solution from your side.
