that's not exactly what I meant
What I had in mind were individual sounds that nokia 3310 makes.
Something like this
Do you mean DTMF (https://en.wikipedia.org/wiki/Dual-tone_multi-frequency_signaling)? Aka the tones each number key makes when pressed. If this is the case you don't need to download them you can just generate them with audacity. There is a special DTMF Tone generator included by default.
