SIP trunk TLS transport protocol

[Flamba1000]

let's see if i understand correctly,

to use TLS instead of UDP as a transport protocol, my provider must give me an FQDN and the relative .pem certificate.

and this certificate has nothing to do with the certificate of my 3cx.

correct?

Thanks so much.

Hi @Flamba1000

Your provider must first of all support TLS. If they do then you will need the root certificate that was used to sign the certificate chain of the providers certificate.
This has nothing to do with the certificate of your 3CX FQDN.
