Hi, I know it is NOT recommended by 3CX (and not supported). However, has anybody been able to setup OpenVPN service in the linux 3CX PBX? We are trying it, and as soon as we start the OpenVPN service the "3CX PhoneSystem 01 SIP Server" shuts down. Almost like it was monitoring the network interfaces on the server and shutting down on purpose. Again: I know this is not recommended. Still, in my scenario I would still like to test it as an experiment. Any experience? Thanks.
