20503: FILE EXTENSION ERROR - unsupported extension on file: 'filename'

Function

send_fax

Explanation

The extension on the supplied file name does not match the allowable values. (The file name extension is the last four characters of the file name. The first character of the extension must be a dot (.). The remaining three characters must be 'txt' or 'tif'. If a PCX to TIFF conversion utility has been set in the ODM using the BFIT tool then a file extension of .pcx is also permitted).

User response

Ensure that files to be faxed have file name extensions which belong to the allowable values.
