Добрый день.
Обнаружено непрохождение входящих вызовов на станции NEAX7400M100MX (SC-2991 C2-0002.03), с платой PN-30PRTA (SC-2885 B1-0002.00). Проблемы возникают с входящими вызовами, поступающими с терминала А на терминал В, на котором установлена безусловная переадресация на терминал С, который является абонентом NEC (А→B→C). При этом, вызовы, поступающие непосредственно от терминала А к терминалу С успешны (A→C). Есть подозрение, что NEC не понимает в Setup поле Facility.
На IPS подобных проблем не обнаружено.
Возможно ли какими-либо программными средствами решить данную проблему, т.е. без замены процессора?
Сообщения SETUP и DISCONNECT прилагаются.
Заранее спасибо.
