一、新建项目 -> 在 "pjproject-2.8" 根目录同级；app
二、附加包含目录 "../../pjproject-2.8/pjsip/include/;../../pjproject-2.8/pjlib/include/;../../pjproject-2.8/pjlib-util/include/;../../pjproject-2.8/pjnath/include/"less
三、连接器 -> 附加库目录 "../../pjproject-2.8/lib/;../../pjproject-2.8/pjlib/lib/;../../pjproject-2.8/pjlib-util/lib/;../../pjproject-2.8/pjsip/lib/;../../pjproject-2.8/pjnath/lib/"ide
四、连接器 -> 输入 -> 附加依赖项 " ws2_32.lib;pjlib-i386-Win32-vc14-Debug.lib;pjlib-util-i386-Win32-vc14-Debug.lib;pjnath-i386-Win32-vc14-Debug.lib;pjsip-core-i386-Win32-vc14-Debug.lib;"oop
五、wireshark抓包： 能看到SIP发送数据，SIP属于OSI的应用层，要求对端可以链接才能看到本条协议数据ui
六、PJSIP流程： this
PJLIB-UTIL初始化 ---> 建立 pool factory ---> 建立SIP endpoint ---> 建立SIP transport ---> 发送短信code
七、主要代码说明：ip
初始化发送内容ssl
status = pjsip_endpt_create_request(sip_endptLocal, &method, &str_target, &str_from, &str_to, &str_from, NULL, -1, &body, &tdata);
if (status != PJ_SUCCESS) {
return status;
}
发送内容ci
status = pjsip_endpt_send_request_stateless(sip_endptLocal, tdata, "", NULL);
if (status != PJ_SUCCESS) {
return status;
}
