DAHDI. Непонятные обрывы связи с Cause 16.
Добавлено: 11 апр 2012, 10:33
Всем привет. Имеем: Debian Squeezy, Asterisk 1.8.10.1 + dahdi_2.4.1.2+2.4.1-parabel_2.4.3 + Quasar E1 (8 потоков, 2 не используется, 4 АТС + 2 потока от Комстар), периодически пользователи жалуются на обрывы связи, т.е. вызов может длиться около минуты, а потом Cause: Normal Clearing (16).
Удалось отловить только это:
Подскажите, куда копать, где искать причину?
