Кстати по просьбе товарищей которые хотели переключаемый режим RI - обратите внимание на пункт 29 - команда CRIPULSE

Есть и не очень хорошая новость - в связи с обнаруженой критической ошибкой в приеме DTMF, будет выпущена дополнительная сборка 8 версии после устранения данной ошибки. SIMCOM извиняется и постарается сделать это как можно скорее.

Обновленые даташиты выложу на сайт сразу по получению.
