I am having same problem with fax. sometimes it works, sometimes it doesn't. I am able to send without a problem, but receiving is hit and miss. I think the Hub's answer machine conflicts with HP Officejet 7410.
I would like to know more about this switch and the right setup. I have heard of a switch that connects to the fax and then to ethernet that does something for VOIP.
Any help would be greatly appreciated.
Thanks,
