maybe try searching some samples on freesound.org?
otherwise, maybe experiment a bit with square wave lfo's on a triangle wave or a sine wave, and bitcrush it a bit

i believe a few wave editors render them (old demo of cooledit pro?) iirc each one is only two sine waves, you can probably find the freqs noted somewhere online.

you can emulate the sounds with a PWM mono-oscillator synth.
maybe a little overdrive to fake it better.

That's right. Here's the dial string "123456789*0#" generated with CoolEditPro:

Process further to taste...

It's just two stacked sine tones each. For the exact frequencies see Wikipedia:

You might want to check out this free online service that will translate numbers into DTMF tones (touch tones):

http://www.dialabc.com/sound/generate/

If you want to know the details of the frequencies involved, this is a decent reference page:

I've saved the best for last. The free audio editor Audacity will generate any DTMF sequence you want, with complete control over tone length, spacing between tones, etc:
