Hi, We're using a 3CX system v10 on a Proxmox VPS with Windows 7 Pro 64bit. Everything works fine, but.... When 3cx phonesystem takes a call and welcomes its caller in the welcome menu, after a certain amount of seconds you notice a really short interruption and the menu resets it selves (starting over again in the menu). I did multiple tests; did an internal test, same problem, connected the 3cx directly on the modem/router, same problem. What solved the problem, but what i don't want, is that I installed 3cx on a standalone desktop (exactly the same settings and installation), instead of the Proxmox VPS. My problems were gone! Does ANYONE have an idea what causes the interruption on the Proxmox VPS? Thanks for your replies!
