title: ConnectyCube React Native VoIP push token issue
body: <p>This is my normal, successful subscrition to apn or gcm channel</p>
  
  <pre><code>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 =&gt; {console.log("RESULT: ", result)})
        .catch(error =&gt; {console.log("ERROR: ", error)});*/
  
      // JS SDK v1
      ConnectyCube.pushnotifications.subscriptions.create(
        params,
        (error, result) =&gt; {
          if (result)
            console.log("RESULT APNS: ", result)
          else
            console.log("ERROR VOIP", error)
        }
      );
    }

  <p>Now I need to use VOIP push notification, but when I try the following code:</p>
  
  <pre><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 =&gt; {console.log("RESULT: ", result)})
        .catch(error =&gt; {console.log("ERROR: ", error)});*/
  
      // JS SDK v1
      ConnectyCube.pushnotifications.subscriptions.create(
        params,
        (error, result) =&gt; {
          if (result)
            console.log("RESULT APNS: ", result)
          else
            console.log("ERROR VOIP LAST: ", error)
        }
      );
    }
  </code></pre>
  
  <p><code>console.log</code> gives me this error :</p>
  
  <pre><code> ERROR VOIP LAST:  {"code": 422, "detail": ["Invalid notification channel specified"], "message": {"errors": ["Invalid notification channel specified"]}, "status": "error"}
  </code></pre>
