You don’t need to do anything besides check your email. You should find that when a fax arrives you will get an email saying that you have received a fax and all you need to do is open the attachment to see what has been faxed to you.

Please remember it can take 5-10 minutes to travel through the system due to the incoming fax being analogue and then needing to be converted to a digital fax that appears in your inbox.
