SIP TLS

[Zol]

Dear Community,

I would like to try registering my SIP Trunk with TLS.
Is this guide still valid for 16.0.676 (Standard Annual) > https://www.3cx.com/docs/secure-sip/

What kind of certificate should I upload here?



Thank you for your tips

Hi @Zol

It's fairly straightforward: Your provider must give you a TLS Root Certificate (.pem) so you can encrypt the traffic. If they have SRV records the system will automatically know where to connect for TLS mode (Auto Discovery option on General trunk tab), or the provider might just tell you to change your port to the one they are listening to for TLS connections
