Hey hey,
just a small UDO to generate DTMF digit tones:
http://juliencoder.de/sound/m_scene_dtmf.zip

It comes wiith an example. If you pick up your phone in Germany and play the 
example to it, it will dial the automatic information system of the train 
service. Funny really. :) Just thought I'd share this. It will become part of 
the m_3d_suite - or a more appropaitely named successor.

Best wishes and keep calling,

Jeanette
