(三)pjsip 监听
1、新建项目 -> 在 "pjproject-2.8" 根目录同级；
2、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/"
3、链接器 -> 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/"
4、链接器 -> 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;"
5、ip转 pj_unit_32
pj_in_addr in_addr;
pj_str_t host = pj_str("192.168.0.55");
pj_inet_aton(&host, &in_addr);
// string ip 转 pj_uint32_t
addr.sin_addr.s_addr = in_addr.s_addr; //0;6、完整代码
