Rapidport capability

Dear all,

I 'm testing rapidport 4 port usb to be used with GFI
Faxmaker 2013. I like it’s size.
I used to working with 8 external modem and Digi Neo Card.

My question :

  1. Is rapidport was designed to work well with GFI Faxmaker. Anybody has tried this before?
  2. If it is not, what product should I use?
