We have done just that for deployment needing to use satellite connection as
only available option. 
It was for a ship serving as a floating laboratory.


It works like this:

Fax over IP (FoIP)

Fax over IP using PBXware uses internal logic to accept/send fax calls as
normal at trunk and the local network level. Difference lies in how it
handles transmitting the faxes across the IP networks (Internet, LAN, WAN
etc.) The process goes as follows:

1.	A fax call is received into PBXware PSTN trunk.
2.	PBXware creates an image file from received fax and sends it to
remote PBXware using IP network.
3.	After receiving the file remote PBXware system converts the file and
calls the local fax machine as a normal fax transmission.

 

Sending faxes out from the ship will work in similar way:

1.	PBXware receives a fax transmission from local fax machine.
2.	PBXware transform the fax transmission into image file.
3.	PBXware then sends the image file to remote PBXware
4.	After receiving the file remote PBXware looks up the destination
number and faxes out using PSTN trunk.
