DTMF dial tones, is there a way? During phone call

Is there a way to make a Construct2-built app dial a phone number, and furthermore, after a few seconds, dial some tones?

For example, call an automated phone service and dial the numbers that will trigger certain service navigation options.

Thanks!!

Trying to write a non-game app with it huh? You do have the ability to call json and call to data on the html page too... maybe those would help...
