Hi Guys,
it looks like that Telnyx support TLS SIP Trunk. Unfortunately, I can't find any manual how to do that. in 3CX documentation I can find only regular setup. Can anyone help?
The template shipped with 3CX is the configuration they support. Anything else is not supported. That being said it's probably something super complicated like changing the protocol to 'TLS' and changing the port. Telnyx support should be able to help.
