3cx and DE410 IP PRO

[clauderegert]

Good evening everyone.
I have a problem with this phone.
It is correctly configured in 3cx, it is registered.
But when I call him from an extension, I don't hear it ringing, and the recipient hears nothing.
The strange thing is that with this phone I can call, but I can't receive.
Reset the fw, reset, but the problem persists.
I point out that the server 3cx is external to the company, when the server 3cx was internal I didn't have this problem.
The dns are correctly configured.

Thanks for your support.

Hi @clauderegert

That model is not in our supported list so we cannot say whether it will work correctly.

The problem is most likely due to the fact that the phone is external, it will need to be configured as per our STUN recommendations otherwise it will not behave correctly.

Even with those recommendations, you may still face issues with it so your best bet is to replace this phone with one from our supported list here: https://www.3cx.com/sip-phones/

Thanks for you support Johns

How can I configure it with the Stun?

I'm afraid I cannot help very much on this matter, like I said this is not in our supported models so I am not aware of its setup options.

The best I can recommend is to replace it with a supported model or wait and see if another forum member who has configured this before manually can share their setup.
