Hello guys, there was such an interesting question in my head. What methods or functions you can make calls to applications, not just standard calls, but as a function of voice calls in WhatsApp, I know it is not easy and not easy, but the priest requires adventure, I ask you to suggest in which directions I should swim. I searched the Internet for spaces, but unfortunately I didn’t find anything, there’s not much about it. I will not thank in advance.

It depends on which protocol you are going to use for voice. If the GSM path is standard, then everything is sour - you can only change the dialer interface and this is through a hack (something like headset emulation), but otherwise you can only call the dialer via standard Intent.ACTION_CALL

And if the voice goes through the IP then life is simpler:

  1. Look in the direction of the SIP API
  2. In addition, there are several proprietary APIs, such as Twilio
