Добрый день.
Есть проблема.
AS5350 IOS 12.2(2)XB5 соединена с Дефинити по R2.
AS5350 принимает от Дефинити звонки по R2 и отправляет в ISDN. Так вот при
покладании трубки удалённым абонентом возможны 2 варианта развития событий
(в зависимости от того, на какой номер звонишь):
- неправильный (на мой взгляд)

===================================================
Что можно сделать в первом случае, чтобы тайм-слот всё-таки освобождался по
приходу Disconnect из ISDN?
Нужно ли пинать телефонистов со стороны ISDN? Может они чего должны
подправить?
