Dear All, I have added: #define PJMEDIA_AUDIO_DEV_HAS_COREAUDIO 1 in config_site.h and then I configured iPhone, and I run my program, it was OK for initialisation, but after I add the account, it got the error: Assertion failed: (pjsua_var.tpdata[0].data.ptr != ((void *)0)), function pjsua_acc_add, file ../src/pjsua-lib/pjsua_acc.c, line 400. I checked the line 400: /* Must have a transport */ PJ_ASSERT_RETURN(pjsua_var.tpdata[0].data.ptr != NULL, PJ_EINVALIDOP); PJ_LOG(4,(THIS_FILE, "Adding account: id=%.*s", //(int)cfg->id.slen, cfg->id.ptr)); pj_log_push_indent(); Therefore, how can I change the code to use the iLBC CoreAudio with iPhone. Cheers, Jack
