I didn't understand how to actually do what you asked :( , but here's 
what I did do:

I set up the dial plan to use sip for a local number, rather than just 
dial out on PSTN over dahdi. That worked. So that must mean the DTMF 
tones get to asterisk over the internal dahdi channel, but for some 
reason are not sent out over the outgoing dahdi channel, right?

I do not hear a continuous tone if I press a key for a few seconds.
