Solved Failed to start 3CX PhoneSystem 01 SIP Server. Core dumped

[EvilX]

Hi there.
I installed the 3cx instance with iso to real server.
After installation and base configuration sip service did't start.
Whats wrong?

Syslog:
Mar 23 01:17:56 local systemd[1]: Starting 3CX PhoneSystem 01 SIP Server...

I found the reason - tun interface.
I dont know why. After I stoped openvpn service - 3CX started.
Any one know, how to fix it? I need openvpn connection to that server.

Hello @EvilX

Please note that OpenVpn is not supported on a 3CX server as it causes issues like the one you are experiencing. The 3CX server should be a dedicated server to avoid any future issues.
