We ran into the issue with being able to see fax forwarding information in the address book of imageRUNNER ADVANCE C5035. We know it is working (faxes are coming to the folder of the computer they suppose to go to) but for some reason address is not showing up, instead it looks like no fax forwarding was setup.
