I've been testing with VMware workstation 5.5 and 6 and 3CX seems to run just fine in either. The guest OS was Windows XP Pro. I will try it in VMware ESX 3.01 shortly and report back my findings.
The back-up and restore feature of this phone system is great. I've moved to and from testing between virtual machines and physical ones and am able to back-up and restore seemlessly. This will make for a very nice desaster recovery (is there such a thing!?).
Also, do you know of a way to automate the backup process?
Thanks,
Jim
