Модем берет трубку через раз.

[Казаков]

Все господа, сил больше нет моих бороться с модемом. Ситуация такая. Модем обычно берет трубку после первого звонка, но иногда он перестает брать трубку вообще. Перед этим никаких манипуляций с ним и с п.о. не проводится. Обычно я лечил это переустановкой драйвера, и помогало (хотя возможно это просто совпадение), но рано или поздно это должно было надоесть и надоело. Я конечно не исключаю возможность собственной криворучности так что...
Вот статистика:

Дальше я отменяю коннект вручную.
При необходимости могу предоставить статистику удачного Callback-a,
надеюсь на вашу помощь.

Как видно из журнала, модем обнаруживает звонки, и драйвер их правильно интерпретирует:

По какой-то причине программное обеспечение не желает посылать команду ответа (ATA). Возможно, неаккуратно поправили драйвер или registry (меняя #cid=1 на #cid=0). Но скорее всего, что-то "не так поставили". Возможно, самый быстрый выход - переставить операционку.

Да, операционку переставил на следующий день и все заработало.
