Hi, I tried to use ipv6 feature and ICE feature together at same time in PJSIP, but it did not work. I made them enable by separate. Is it a bug or I need to do sth to make them enable at same time? Things I did on it: In the pjsua_app.c app_config.ipv6 = PJ_TRUE ; app_config.media_cfg.enable_ice = PJ_TRUE; Thank you, Fatih Cakir
