Hi,

If you use a system Hosted By 3CX, the only supported method of running your phones is via SBC only.
https://www.3cx.com/docs/3cx-tunnel-session-border-controller/

We do provide support for STUN on those systems, if you have issues you will have to troubleshoot them yourself

The requirements you see in that article will not be necessary if you install an SBC, we highly recommend you install one at the phones site which should largely solve any problems you might face with IP Phones, make provisioning easier, and increase the security of your lines through encryption.
