Самопроизвольный отбой абонента MSAN1000

[Sergey Orlov]

Здравствуйте!
Используем Ваше оборудование MSAN1000.
Обнаружилась проблема:
Абонент MSAN совершает исходящий звонок. Встречная сторона отвечает, но после после 2х секунд установления соединения вызов отбивается со стороны MSAN с причиной Reason: Q.850;cause=41;text="Temporary failure".
Ниже представлена SIP трассировка проблемного звонка. Прошу помочь в решении проблемы. Спасибо.
