How to capture the key presses during a call. They way user navigates IVRs when they call an operator they press 1 or some other key to select language and so on. Is there a way to programtically capture these key presses?

On the client side? No. There's no API for that. On the other side they obviously can. The only thing I could think of would be in you could record from the mic and do signal analysis looking for a dtmf tone, but my dialer has an option not to make beep noises when keys are pressed.

@user924 Those happen in the other end- on the computer that receives the call. Not on the client's phone – Gabe Sechan Apr 03 '18 at 13:02

I understand this, how do they get such events? for example if I have two android devices, during a call can I detect numbers on some device user pressed on the other device ? – user924 Apr 03 '18 at 13:52
