Hi Experts, I have this pjsip build pjproject-1.8.10 . I am trying to run it on windows 5 mobile. In my config file, i have set it to use wmme direct. #ifndef PJ_WIN32_WINCE #define PJ_WIN32_WINCE 1 #endif #define PJ_CONFIG_WIN32_WMME_DIRECT 1 #include <pj/config_site_sample.h> #define PJMEDIA_HAS_G729_CODEC 0 #define PJMEDIA_HAS_L16_CODEC 0 #define PJMEDIA_HAS_G711_CODEC 0 #define PJMEDIA_HAS_GSM_CODEC 0 #define PJMEDIA_HAS_ILBC_CODEC 0 #define PJMEDIA_HAS_G722_CODEC 0 #define PJMEDIA_HAS_SPEEX_CODEC 0 #define PJMEDIA_HAS_G7221_CODEC 0 When i am running the pcokect pc app, the registration is happening.
