Добрый день!

Прошу помощи коллективного разума.
А проблема вот в чём:
Скрещиваю ap300b с SoftX(call agent) по mgcp.
При входящем неотвеченном звонке порт FXS ap300b остаётся в состоянии BUSY , при следующих входящих звонках у звонящего абонента в трубке КПВ, телефон на ap300b молчит.
И выйти из этого состояния можно только через подъём трубки на
телефоне ap300b.
