I am sending dtmf tone via this code.
String number="tel:+962791212121,2,3,3";
Intent c1= new Intent(android.content.Intent.ACTION_CALL, Uri.parse(number));
startActivity(c1);
It send perfect dtmf as this. 2+(2 sec delay)+3+(2 sec delay)+3.
but I want to remove that 2 sec delay or I want to control that delay.
How can I control (2 sec delay)?
Or any other method to send dtmf tone during call?
To remove the delay remove the comma.
