I want to make a call control CSTA with pjsua, and I need to begin with a INVITE with content type=application/csta+xml, and not "sdp". I was trying with pjsua_call_make_call, but seems that sdp negotiation (and contentype) is harcoded inside. Thats my try... pjsua_msg_data msg_data; pjsua_msg_data_init(&msg_data); msg_data.content_type = pj_str("application/csta+xml"); pjsua_call_make_call( current_acc, &tmp, 0, NULL, &msg_data, NULL); Anybody can help me how to make a invite with only content type=application/csta+xml ? and without make very internal code (Im a newbie...)
