Does anyone success on enabling APS-Direct on Symbian S60 3rd MR? How can I do to enable it? I tried to set #define PJ_CONFIG_NOKIA_APS_DIRECT 1 #define PJMEDIA_AUDIO_DEV_HAS_SYMB_APS 0 #define PJMEDIA_AUDIO_DEV_HAS_SYMB_MDA 0 #define PJMEDIA_AUDIO_DEV_HAS_SYMB_VAS 0 in file config_site_sample.h but when I make call, my app crashes right after receiving SIP 200 OK.
