6004 подключен к офисной атс несколькими линиями
при вызове на линию №1 по хотлайну вызываем абонента - связь ОК
Абонент нажимает трансфер и набирает номер (занимает линию №2) - связь ОК
В момент когда абонент отключается и по идее должно произойти соединение линий 1 и 2

Линия 2 - связь рвется (busy)
Линия 1 остается висеть на холде и вернуться на нет возможности
