есть ли способ отключить вызов программно в ios

Question

Примечание: Я создаю это приложение только для внутреннего использования.

У Apple есть структура под названием CoreTelephony, которая обеспечивает обратный вызов при приеме, отключении вызова и т. Д. Так что я пытаюсь получить вызов, я мог бы отключить вызов или перевести вызов на другой номер.

Я потратил много времени на это, но я не понимаю, как отключить вызов. Любая помощь будет оценена.

Это не мой код, я нашел его на GitHub, я испытал это сам и изменил его для своих нужд, но вы все еще можете использовать его, просто удалите мой дополнительный код:
