В нашем проекте мы реализовали Sinch в веб-приложении angular 2.
Пока почти все работает нормально, за исключением случаев, когда я пытаюсь вызвать пользователя, используя демо-версию телефона synch.
Когда приложение работает на переднем плане, оно будет звонить, и соединение будет выполнено.
когда приложение работает в фоновом режиме, ничего не произойдет.
В приложении angular не запускается eventlistener onCallProgressing, страница просто ждет, пока не выплюнет это сообщение об ошибке: 
Похоже, проблема заключается в отсутствующих функциях jquery, так как я переписал проект на angular.
Мне нравится знать, что я могу сделать, чтобы исправить эту проблему с помощью API-интерфейса sinch.
полная ошибка стека ошибки следующая:
