Hi All, i'm trying do some calling test with pjsip , when i call makeCall function i catch one exception : Unalbe to find default audio device. i think there maybe something missing when i compiling pjsip project, in my windows 7 platform i installed SDL, and ffmpeg , and my default config_site.h file like below : " #define PJ_CONFIG_MINIMAL_SIZE #define PJ_CONFIG_MAXIMUM_SPEED #define PJMEDIA_HAS_VIDEO 1 #define PJMEDIA_VIDEO_DEV_HAS_SDL 1 #define PJMEDIA_VIDEO_DEV_HAS_DSHOW 1 #define PJMEDIA_HAS_FFMPEG 1 " is there i missing something in this config_site.h file , cause i can't initialization my voice device correct ?
