Asterisk. Конфигурационный файл cdr_tds.conf.

Asterisk может хранить записи CDR в базе данных FreeTDS (включая СУБД MS SQL), используя модуль cdr_tds.so. При загрузке этого модуля используется конфигурационный файл cdr_tds.conf.
После успешного установления соединения данные CDR записываются в эту базу данных.
