Здравствуйте!
Есть два Астериска: в Украине (1.4.24.1) и США (1.4.22) связь через IAX2.
На американском сервере стоит карточка Digium TE122B.
Cуть проблемы: из Украины long distance звонки,например, в Канаду или куда-угодно, идут через 1-ну линию (442-771-7000), а из США - через другие 22 линии, напрямую (т.е. если ext 7007, то будет использована линия 442-771-7007). Без каких-либо причин и изменений в настройках линия 7000 стала возвращать 'all-circuits-busy' при попытке осуществить LD звонок.
Остальные же 22 линии работают на "ура", т.е. из США звонки проходят, из Украины - нет.

Вот логи неудавшегося звонка,с pri debug span 1:

Двумя месяцами ранее была похожая проблема - но тогда не работал весь диапазон линий. Это произошло из-за ДОС атаки, и американский провайдер заблокировал LD звонки. Сейчас я созванивалась с провайдером - говорят с их стороны блоков нет.
Пожалуйста, помогите разобраться в проблеме. Заранее спасибо.
