Q: 

Uplink DTMF tone generation

Greetings

Is there any way I can dynamically generate uplink DTMF tone (ie the receiver hears it)?

When I looked at the android source code I saw a function called startDTMF() which is exactly what I need, but I couldn't find any API that allows me to access that function...

I then thought of using ToneGenerator and tried to inject the sound to the mic stream, and again I couldn't find a way to achieve this...

Any help is appreciated.

HELP!!!!!

A: 

Perhaps the android.media.ToneGenerator class in the SDK can help?

Yes I tried that, but it's only good for generating downlink dtmf tone (ie what YOU hear). As I mentioned I tried to find a way to inject the audio to the mic stream but no luck... :(

Ah, I see, sorry for the misunderstanding!
