ConnectyCube React Native VoIP push token issue

Question

This is my normal, successful subscrition to apn or gcm channel

subcribeToPushNotification(deviceToken) {
    const params = {
      notification_channels: Platform.OS !== 'ios' ? 'apns' : 'gcm',
      device: {
        platform: Platform.OS,
        udid: DeviceInfo.getUniqueId()
      },
      push_token: {
        environment: __DEV__ ? 'development' : 'production',
        client_identification_sequence: deviceToken
      }
    }

    // JS SDK v2
    /*ConnectyCube.pushnotifications.subscriptions.create(params)
      .then(result => {console.log("RESULT: ", result)})
      .catch(error => {console.log("ERROR: ", error)});*/

    // JS SDK v1
    ConnectyCube.pushnotifications.subscriptions.create(
      params,
      (error, result) => {
        if (result)
          console.log("RESULT APNS: ", result)
        else
          console.log("ERROR VOIP", error)
      }
    );
  }

Now I need to use VOIP push notification, but when I try the following code:

subcribeToPushNotificationVoip(deviceToken) {
    const params = {
      notification_channels: Platform.OS === 'ios' ? 'apnsvoip' : 'gcm',
      device: {
        platform: Platform.OS,
        udid: DeviceInfo.getUniqueId()
      },
      push_token: {
        environment: __DEV__ ? 'development' : 'production',
        client_identification_sequence: deviceToken
      }
    }

    // JS SDK v2
    /*ConnectyCube.pushnotifications.subscriptions.create(params)
      .then(result => {console.log("RESULT: ", result)})
      .catch(error => {console.log("ERROR: ", error)});*/

    // JS SDK v1
    ConnectyCube.pushnotifications.subscriptions.create(
      params,
      (error, result) => {
        if (result)
          console.log("RESULT APNS: ", result)
        else
          console.log("ERROR VOIP LAST: ", error)
      }
    );
  }

console.log gives me this error :

 ERROR VOIP LAST:  {"code": 422, "detail": ["Invalid notification channel specified"], "message": {"errors": ["Invalid notification channel specified"]}, "status": "error"}

voip token example: 4dd23c212d2a8865c4747ee278de0947d0de80445400f8f85cdb5a6f3923cb74

I am using the Universal (Sandbox & Production & VoIP) SSL certificate

For VoIP it should be

 notification_channel: "apns_voip"

• For VoIP pushes it requires to generate a separated push token when subscribe a user, please see how to get it https://github.com/react-native-webrtc/react-native-voip-push-notification#usage

• Then when token is retrieved, you need to subscribe to voip pushes by passing a ‘apns_voip’ channel in a subscription request

• Them when you want to send a voip push notification, also use ‘apns_voip’ channel when create an event
