Kotlin

Fazer uma ligação

Por fim, vamos configurar a função de fazer chamadas a partir deste aplicativo.

No onCreate função, adicione o ouvinte de desligamento do RTC:

client.setOnCallHangupListener { callId, callQuality, isRemote ->
  onGoingCall = null
  hideUI()
  startCallButton.visibility = View.VISIBLE
  waitingForIncomingCallTextView.visibility = View.VISIBLE
}

Este ouvinte de chamada irá lidar com a situação em que a outra pessoa na chamada desligar. Quando isso acontecer, reinicializamos o aplicativo para seu estado original.

Adicione o código do ouvinte de clique para iniciar a chamada em onCreate também:

startCallButton.setOnClickListener { startCall() }

Para iniciar a chamada após pressionar start call botão “Adicionar o” startCall método interno Mainctivity classe:

@SuppressLint("MissingPermission")
fun startCall() {
  client.serverCall(mapOf("to" to otherUser)) {
      err, outboundCall ->
    when {
      err != null -> {
        connectionStatusTextView.text = err.localizedMessage
      }
      else -> {
        onGoingCall = outboundCall
        hideUI()
        endCallButton.visibility = View.VISIBLE
      }
    }
  }
}

O método acima inicia a chamada.

Webhooks

À medida que você for realizando a ligação, por favor, mude para o terminal e observe o /voice/answer endpoint chamado para recuperar o NCCO:

NCCO request:
  - callee: 447700900000

Além disso, à medida que a chamada passa por várias etapas, /voice/event está recebendo eventos:
