"Not connected to the Internet", and "not connected to a LAN" are very different things. I doubt VOIP would work if the server was not connected to a LAN. There could be quite a few things on the LAN, depending on it's size, such as viruses, malware, and even users doing scans of the network. Don't assume that "out there" is insecure, and "in here" is secure. That's one of the biggest mistakes to make when creating a secure environment.
You're right. I was thinking like a phone tech -- that the VOIP system's wiring was still separate from the regular LAN.
But even with old-school phone switches, your support contract would require software updates at regular intervals and unless you had redundant hot-failover equipment, that would involve scheduled downtime.
