I am trying to troubleshoot a problem with Legal Size Faxes being truncated. We use the built in 3CX fax server to receive emails which are then forwarded to an email address. For standard letter size faxes it works perfectly. My problem is that we have a large corporate customer who sends us important legal size documents via fax from their service center in another country and these legal size documents are being truncated to letter size. I have tried to send legal size tests from the online fax services we use, but these services all wonderfully reduce to letter size before sending, so I am unable tell if the problem is in the 3CX Fax Server or with the sender. As the sender is a large service center, I would assume they would have long ago fixed this if their system was the problem - but who knows. My question is does anyone know if there is a limitation on what page sizes the 3CX fax server can receive? Is there a tweak somewhere that can be adjusted to not truncate pages or to reduce over-sized faxes to letter?
