Обрывы при звонках в Мегафон (продолжение)

В продолжение этой темы: http://asterisk-support.ru/question/66056/obryvy-pri-zvonkakh-v-megafon/, потому как создать ответ не знаю, а добавлять дебаг в комментарий наверное будет немного жестко

Лог и PRI ниже. Я, конечно, не эксперт в дебагах, но ничего странного не заметил. Завершение вызова с Cause: Normal Clearing (16) to originator. Есть у кого идеb, что делать дальше? И спасибо что кто-то тратит время на чтение этих логов
