I am interested in handling incoming video or voice calls on WhatsApp programmatically, using languages such as NodeJS, PHP, or Java. I have searched online but only found information about handling phone voice calls using Twilio service or other services. I want to know if it's possible to:
- Receive incoming WhatsApp calls
- Answer the call
- Receive streaming data and send data back simultaneously in a bidirectional connection
- End the call.
I would appreciate any help in achieving this functionality.
