Using ActFax on a virtual machine
Can I use ActFax on a virtual machine?
Virtual machines (i.e. VMware ESXi, Hyper-V) would by no problem with ActFax. It is recommended to use at least ActFax version 6.10 when running the fax server on a virtual machine. On a virtual machine, internal fax boards do not work.
For analog fax lines, a possible solution would be using a network based USB hub to connect normal external USB fax modems to the system (i.e. Sylex DS-510 or Digi AnywhereUSB).
