Yealink Phone not registring

[epbarnard]

I have a 3cx hosted server. Softphones does register and works 100% but I can not get the desk phones to register. Who can advise me on manually setup up the phone to work?

If it's 3CX hosted they only support using an SBC. If you have that set up they should just show up in the server. https://www.3cx.com/docs/3cx-tunnel-session-border-controller/

You can attempt STUN but don't expect it to work

Are you using supported phones? and If so, have you tried using our step by step guide yet for your model?
