Incoming fax message are delivered as a PDF, but the PDF does not have the correct A4 format. How can I force that?
Set on the XPhone Server under SETTINGS -> UM -> FAX -> GENERAL on the "Advanced Settings" a new parameter called Fax2Mail\Tiff2Pdf with the value
Save the parameter and then the mainsite itself. Now the UM services should be marked to restart. Start the UM services.
