Для тестирование некоего оборудования понадобился "тестовый стенд", который пробрасывает звонок с одного обычного телефона на другой через E1.

Примерно так:

Тел.1                                                      PRI0
          > IP-АТС <--H323--> AS5350 <      > тестируемое оборудование

Тел.2                                                      PRI1

Тестируемое оборудование абсолютно прозрачно и другим концом подключается ещё кое-куда, что в данной ситуации совершенно непринципиально. Не будем уточнять, для каких целей оно используется. ;)

Затык, как обычно, образовался в циске.
В неё из IP-АТС (АГАТ-UX, очень люблю сиё железо) приходит номер вида 91xx, в неё обратно надо отправить номер вида 1xx. Всё казалось бы просто.
Однако:

Не пойму, в каком месте он "De-Activated".

Важное примечание: в данной ситуации вместо тестируемого оборудования используется перекрёстный патч-корд, ибо доступ к оборудованию связан с получением допусков и пропусков, поэтому хотелось бы отладить сначала на обычной меди.
