Настройка Wildcard TDM410P. Channel InAlarm

Добрый день!

Помогите, пожалуйста, решить проблему настройки указанной платы с FXO-портами.

Asterisk 1.8.15.1 + FreePBX 2.10 В плату воткнуты и настроены 2 линии. Как видно из логов сама плата везде пишет ОК, но в статусе канала в Астериске "InAlarm: 1".

При исходящем звонке, естественно, Busy. Подскажите, в чем может быть причина алармов. С линией все в порядке, если подключить обычный телефон звонки ходят.
