To be honest, the customer knows that this can be a stop issue:
"he only want to make a try..."

So, DCD is needed, for properly handling the fax to serial protocol?
(I'm wondering how faxsetup managed to complete without problem, perhaps 
is test only some AT commands and thus it does need all the things)

If you can suggest a multiport fax card that is supported by VMWARE ESX 
let me know...

I know that I can setup a physical machine with linux and a multiport 
fax card (and I have already done this kind of setup for many of our 
customer), buy this particular customer want to use "virtual servers" 
and thus he has to live with problems that this kind of solution has...
