    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 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.

    I made a Yoshimi instrument (.xiz file) for DTMF.

    Can find DTMF files here:

    <https://www.mediacollege.com/audio/tone/dtmf.html>

    They're in mp3 format and don't include dialtone, hangup, and ring-pstn.

    You don't need prerecorded files. Sox can generate DTMF sounds for you anytime you need them:
