Приветствую

Подняли на Cisco 2811  PRI E1.
Звонки проходят нормально со станции на астериск и обратно,

Но проблема в том, что при звонке со станции на астериск звонок приходит, говорим, ложим трубку, И, с этого момента начинаются повторные вызова с cisco на asterisk с интервалом 40-45сек.

Если с астериска звонить через cisco, повторов нет.

Схема:
Станция-Е1-Cisco2811-eth-Asterisk(482600)

Что не так, просветите, пожалуйста.
