Дублирование CDR в логе

[san]

Анализируя логи присланные пользователем я заметил, что каждая запись CDR дублируется по два раза. Скачал лог с нашей АТС и там тоже самое. Судя по всему VE-01 шлёт по два сообщения на каждую CDR. Может быть это сделано для повышения вероятности передачи?
Думаю, что дублирование захламляет лог, предлагаю избавиться от этого эффекта.
(оригиналы логов можно скачать с нашей АТС)
