Nginx用做sip代理

=s_pcqq_aiomsg

看了这篇文章的方案一，我专门试了试，记录如下：

测试环境为：

fs1（5080 --- nginx --- fs2（5060）

局域网同一个网段，fs1把呼叫送到nginx的5060，后者代理到fs2的5060

第一步，fs1和fs2默认配置，sip call flow如下：

fs1       nginx        fs2

    invite--->

                  invite--->            

                 <---200

<---200

ack------------------->

坏了，ack直接发到fs2，没有经过nginx

第二步，调整fs1和fs2的配置，ext-sip-ip指向nginx，localnet.auto deny所有

再测试，现在ack可以经过nginx，bye也正常

第三步，继续调整fs1和fs2配置，ext-rtp-ip指向nginx，rtp也可以通过nginx转发，最后的结果是：

fs1                        nginx                       fs2

              sip5080<----

                                 --->sip 5060

         rtp(2000-2099) <---

                                 --->rtp(30000-30099)

结论到底如何，看官来总结吧

最后附上nginx配置文件：

#fs1:
#192.168.1.126
#sip:5080
#rtp:2000-2099#nginx
#192.168.100.75#fs2:
#192.168.1.12
#sip:5060
