Habe nochmal eine Teles Faxkarte eingebaut und getestet. Leider erfolglos. Habe ziemlich alle Emulationen probiert.
Fehler:

>Telephone device is activated
>Waiting For Fax Command
FAX>Sending Started
FAX>Error: Fax Time out: no response was received in the expected time.
>Waiting for disconnection
FAX>Fax Operation did NOT complete successfully
>Disconnected

Schade
