The mechanism of FAX ME is that the server receives FAX data as a TIF file, converts TIF to a PDF file, and turns it into an email attachment.

When the file conversion fails in any way, the FAX data may be sent as a TIF file.

I received a sent result report via email. It says "Could not send FAX."

If the sent data included password, special strings or functionality, transmission may fail. In that case, please remove

password, special strings or functionality and try again.

“Open as iPhytterFAX” is not displayed.

This may be attributed to iOS5's specification of displaying only a maximum of nine applications. To resolve this, please update to iOS6
