Outgoing call from mobile device to web

Android
1

I have trouble with connecting between browser and mobile device. When I make a call from the web to the phone, everything works well. But when I call from device to Web, I can’t get connect.
iceconnectionstatechange listener detected peerConnection.iceConnectionState === 'checking' (or failed)
“react-native-webrtc”: “^1.75.3”,
“react-native”: “0.62.2”,

export function* initConnectionSaga(action) {
  const stream = yield select(state => state.rtc.localStream);
  const user = yield select(state => state.user);
  const sender = getSelf(user);

  socket.emit('rtc', { event: 'peer-video', sender, user: action.peer });

  const peerConnection = new RTCPeerConnection(configuration);
  peerConnection.addStream(stream);
  yield put({ type: Actions.RTC_SETUP_LISTENERS, peerConnection, peer: action.peer, sender });
  yield call(sendOffer, peerConnection, action.peer, sender, stream);
  yield put({ type: Actions.RTC_PEER_CONNECTION, peerConnection, peer: action.peer });
}


const sendOffer = (peerConnection, user, sender, stream) => {
  peerConnection.createOffer()
    .then(desc => {
      peerConnection.setLocalDescription(desc).then(() => {
        socket.emit('rtc', { event: 'offer', offer: peerConnection.localDescription, user, sender })
      });
    });
};

const sendAnswer = (peerConnection, user, sender, offer) => {
  peerConnection.setRemoteDescription(new RTCSessionDescription(offer))
    .then(() => peerConnection.createAnswer()
      .then(desc => {
        peerConnection.setLocalDescription(desc).then(() => {
          socket.emit('rtc', { event: 'answer', answer: peerConnection.localDescription, user, sender });
        });
      }));
};

const setRemoteDescription = (peerConnection, answer) => {
  const remoteDesc = new RTCSessionDescription(answer);
  peerConnection.setRemoteDescription(remoteDesc);
  return peerConnection;
};

Please, help. I sat on this problem for a week, but nothing worked out.

Please, guys!
Maybe one of you has this problem and you were able to find its cause or (in the ideal case) its solution :exploding_head: :exploding_head: :exploding_head:

I can give you any logs, package versions, code snippets and other))

Try adding these options in createOffer:

peerConnection.createOffer({
      offerToReceiveAudio: true,
      offerToReceiveVideo: true,
    });
