I have not found any solutions online so I will try and see if someone knows what’s up here
So, I have setup a VPN on my server and everything is working fine (phones can connect, make phone calls, etc.)
The problem is, I made some tests and it appears phones can still connect and get service even if they are not on the vpn.
Is there a way to prevent any connection except those that come from my VPN ? Does it have something to do with the port 5061 ?
Thanks in advance
