Hello,

I looked around for the old Sun DTMF .au files, wasn't able to find them.

However, just came across this in my installation of Zoom:

-rw-r--r-- 1 root root  16296 Aug 17 20:15 dtmf_8.wav
-rw-r--r-- 1 root root  16296 Aug 17 20:15 dtmf_9.wav
-rw-r--r-- 1 root root  12392 Aug 17 20:15 dtmf_a.wav
-rwxr-xr-x 1 root root  12392 Aug 17 20:15 dtmf_dial.wav
-rw-r--r-- 1 root root  16296 Aug 17 20:15 dtmf_star.wav
-rw-r--r-- 1 root root 409666 Aug 17 20:15 ring_pstn.wav

They are:
$ file dtmf_5.wav 
dtmf_5.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, 
mono 16000 Hz

So should be able to convert them to 8-bit ulaw, if that's what you
want for your Pi experiments.
