I know it's possible... but how can I send DTMF digits after the call answers without the tones being audible?

Windows Mobile 5 or 6

Is there an API call for this?

I don't think so.   the DTMF (Dual-tone multi-frequency) are audible  - do you mean send other commands but not using DTMF ?

I know it can be done. I have an app (Handheld Contact - ACT! of WinMob) that dials a number:
           xxxxxxxxxx
Then, sends the DTMF string:
          *#xxxxxxxxx

The 2nd part was audible, but the developer made a change and suppressed it
