I have a FreePBX server running on Vultr and I want to do 2 things:
- Enable TLS on port 5060 and SRTP.
- Create a VPN server for clients that don’t support TLS.
I have a couple old ATAs that don’t support TLS but I can create a VPN tunnel using OpenVPN on the router. What I fail to understand is how do I set up FreePBX/Asterisk so that clients coming through the VPN don’t need to use TLS and SRTP while clients not coming through VPN do? I am using PJSIP for all extensions and trunks. Thanks!
