WhatsApp calls surface through the call event on the socket. Baileys does not answer calls, but you can detect them and reject them programmatically.

​
Listen for incoming calls

Subscribe to the call event to receive WACallEvent[] payloads. Each event carries the id of the call and the from JID of the caller, along with a status field (offer, accept, reject, timeout). 
sock.ev.on('call', async (calls) => {
  for (const call of calls) {
    console.log(`Call ${call.status} from ${call.from}`)
  }
})

​
Reject a call

Use sock.rejectCall(callId, callFrom) to decline an incoming call. Pass the id and from values from a call event whose status is 'offer'. 
sock.ev.on('call', async (calls) => {
  for (const call of calls) {
    if (call.status === 'offer') {
      await sock.rejectCall(call.id, call.from)
    }
  }
})
Baileys cannot accept or carry voice/video calls. Rejecting is the only supported action for incoming calls.
