这个测试程序是从eXosip原有的测试程序改造的。原程序是tools 目录下的 sip_reg.c
本程序主要改造了这几个地方：
1） eXosip_event_wait（） 函数的超时时间，从原来的1ms 修改为50ms
2） 对于初次注册时，服务器返回401的情况。 调用函数 eXosip_add_authentication_info（）发送鉴权信息。
其余的内容基本没改，在我们的sipserver 上面注册成功了。
从这个例程中 我们可以看出sip鉴权的基本流程
从sip角度看， 注册过程是这样的：
客户端 server
| --------regester ---> |
| <----------401------ |
| ---regester + nonce -》 |
| 《----------200-------- |
其中 nonce中带有鉴权信息。形如：
Authorization: Digest username="buxiangyi", realm="Yate", nonce="143e882c902a9c38a3286e9043c35d40.1366083396", uri="sip:172.16.50.189:5060", response="8119330abd3ff5e4e26d2fa87b563b39", algorithm=MD5
对于 eXosip， 其处理过程如下：
1)eXosip_init (初始化)
|
v
2)eXosip_listen_addr (监听sip端口)
|
v
3)eXosip_register_build_initial_register (构建一个register)
|
v
4)eXosip_register_send_register (发送register)
|
v
5)eXosip_event_wait (等待对端事件)
|
v
6)eXosip_execute (处理事件,调整内部状态)
|
v
7)eXosip_automatic_action (根据当前状况，发出响应消息)
之后应循环执行 5）-》 7）

执行结果
写脚本reg.sh(buxiangyi是我们测试用账号):
./sip_reg \
-r sip:172.16.50.189:5060 \
-u sip:buxiangyi@172.16.50.189 \
-c sip:buxiangyi@172.16.50.189:5060 \
-U buxiangyi \
-P buxiangyi \
-p 5060 \
-e 1800 \
-d
执行脚本：
hl@hl-VirtualBox:~/linphone/test_osip_linux$ ./reg.sh

。。。
可以看到客户端收到401之后， eXosip可以自动处理，向server继续发送带nonce的register，之后注册成功
