Because it is more than a simple 'DSP' library: it specialises in
telephony DSP, including FAX generation/recognition.

So, you give it a tiff file, and it generates the sounds to send on the
line. Conversely, when receiving a FAX, you feed it the sound from the
line, and it generates a tiff file. More or less... ;-)
