Adding a DTMF dialer shouldn't be much of a problem, the tones are available on the net.
As for adding other userfull tones, I'm sure I don't know what you mean <_<
I dont mean that red box tones would be or should be included or any think like that, just all the tone need to use phones networks around the world.
I was just messing with you there
. As far as I know the DTMF tones are standard worldwide, so one set should do it.
I'll need to experiment a bit to find the best way to play the tones, I haven't messed with this kind of thing since I had a Psion 3a.
