Testing a SBC and phone wont provision

[ElementalWindX]

I have a 3cx in vultr hosted, and a sbc beside me with a fanvil x6u.

I have the sbc connected to my 3cx in vultr just fine showing online several hours.

The 3cx can see the phone under phones listed as new in bold. I assign it to an extension and it saves in 3cx, but the phone never provisions.

What am I missing here that is stopping this phone from provisioning?

Is the phone on current firmware?

So provisioning is the process of pulling the configuration from the PBX. The normal culprits would be:

- Can the phone reach the management console? Since the SBC seems to have provisioning and the phone and SBC are on the same network then most likely yes.
- Can the phone read the configuration? This is where the firmware comes into play. If the phone is on an older firmware it may not trust the LE certificate used by the PBX in which case it won't be able to pull the configuration file. So as @SteveITS mentioned, make sure you are on the current firmware as recommended by 3CX.

Make sure 'Block Remote Tunnels **' is unticked under Options



Check the blacklist and remove any IP addresses

Are there any internet restrictions at the SBC site , as you need to allow https, ntp traffic out.

any chance you change local IP adress on SBC ?
If you did prepare your SBC with another IP than the one actually in use , then use the previous one or set the new in console
