Thanks for your responses.
Grenville, can you tell me which Zimbra you have, how much this cost you per month?
Draugman, can you also tell me how much the Updox cost you and how much per month?
I have a dedicated fax line now and a fax machine. So if I use either Updox or Paperport, I would have to get a computer w/ fax modem to hook up to the dedicated fax line and have updox or paperport running 24hrs. And the incoming faxes would come in electronically and then I decide what to keep and to import into AC. AC prefers updox because it does it automatically?
With Zimbra I can still use my existing fax line?
