Title: AW: [hylafax-users] Fax Performance

Thomas,

The file is called c000000001 (the number is the so-called comm-number and increments with every fax. You will find it in the log subdirectory of hylafax. To find out what comm-number a fax received, check the xferfaxlog file in the etc subdirectory of hylafax. "man xferfaxlog" will give you explanations on the structure of this file.

Hi Lee Howard,

Thank you.
