If you are using the new I4B, then you should write as a small CAPI 
application, that answers the call, plays back a message and waits for a 
DTMF. The CAPI version in the new I4B, for passive ISDN cards supports DTMF 
detection and ECHO cancellation. You will need both to have success with your 
solution. You can look at the source code for capitest and chan_capi, to see 
how CAPI messages are processed and created.
