СвязьПроект

Здравствуйте, прошу помощи, т.к. сам уже ничего не могу сделать с этой проблемой.
Есть IP-шллюз AP700 (4xFXS),есть Cisco соединенная по Е1 PRI c АТС Panasonic TDA-100.
Проблема вот в чем:
1.Звонки проходят в обе стороны, но разговор слышен только в одну с сторону, от шлюза в АТС.
2.При звонке со шлюза на АТС нет КПВ.
Не могу понять в чем проблема.
Пожалуйста подскажите кто может.

Если пытается соединиться, но busy, значит кодек не понимает, хотя 711 - странно.

Нет занятости нет, соединение устанавливаеться, звонок проходит, только вот слышно в одну сторону, от AP700 в сторону Panasonic'а.
Кодек везде одинаковый, даже в PRI между Cisco и Panasonic.

Будем думать дальше....
