SIM900. Нет мелодии звонка. Опции

[RadikX]

Динамик (8 Ом) подключен через последовательные резисторы 22 Ом к ногам SPK_P и SPK_N. При дозвоне нет мелодии звонка. При подъеме трубки разговор слышно. Громкость устанавливаю. В чем может быть проблема? Лог обмена прилагаю. (Звонок длился около минуты).

UPD: Мелодию слышно, но тихо. 50 омный динамик слышно лучше, но тоже гораздо тише чем было SIM900B.
