Problem With Sending Dtmf Tones From Android App Over An Active Call

The DTMF tones are getting generated on my Experia 10 [Android 2.1]. The problem is, I was expecting this kind of behavior :- I call a number, and the call is accepted at the othe

Solution 1:

I want to know a way, using which I can send DTMF signals over to the other end through a normal phone call.

Android applications have no access to the in-call audio stream. You can fake a it a bit in speakerphone mode.

Is there a way to intercept an outgoing call and generate DTMF in between that call ?

No.
