Sending DTMF tones

During calls, how to send DTMF tones so that I can remotely control my appliances?

How to do DTMF tones (Dual-tone multi-frequency signaling) with Android: http://developer.android.com/reference/android/media/ToneGenerator.html  

How with AI2?   Perhaps use the ActivityStarter .   You might want to try using a series of 10 or 12 recorded DTMF tones and using the Player component...that probably would NOT work as the Player probably will not work during a phone call as part of its design.

There is not capability in the AI2 phone component to generate the DTMF tone.

Yes, I did using "sound", when the button click, dtmf#8.wav sounds.
