Здравствуйте,
Изначально все нормально работало.
Хотел попробовать изменить используемый кодек. Предварительно сохранил конфигурацию. После внесенных изменений, перестали работать как исходящие звонки в город, так и прием входящих звонков. Залил обратно сохраненный конфиг. Прием звонков заработал нормально, исходящие звонки не проходят. Подскажите, пожалуйста, в чем может быть дело?

Текущая конфигурация:
