FreeSWITCH 使用 lua 脚本 接管 分机注册,鉴权等
1. 更改lua.conf.xml配置
<configuration name="lua.conf" description="LUA Configuration">
<settings>
<!--
Specify local directories that will be searched for LUA modules
These entries will be pre-pended to the LUA_CPATH environment variable
-->
<!-- <param name="module-directory" value="/usr/lib/lua/5.1/?.so"/> -->
<!-- <param name="module-directory" value="/usr/local/lib/lua/5.1/?.so"/> -->
<!--
Specify local directories that will be searched for LUA scripts
These entries will be pre-pended to the LUA_PATH environment variable
-->
<!-- <param name="script-directory" value="/usr/local/lua/?.lua"/> -->
<!-- <param name="script-directory" value="$${script_dir}/?.lua"/> -->
<param name="script-directory" value="$${script_dir}/"/>
<param name="script-directory" value="$${script_dir}/?.lua"/>
<!-- 接管分机注册 -->
<param name="xml-handler-script" value="user_auth_xml.lua" />
<param name="xml-handler-bindings" value="directory" />
<!--<param name="xml-handler-bindings" value="dialplan"/>-->
<!--
The following options identifies a lua script that is launched
at startup and may live forever in the background.
You can define multiple lines, one for each script you
need to run.
-->
<!--<param name="startup-script" value="startup_script_1.lua"/>-->
<!--<param name="startup-script" value="startup_script_2.lua"/>-->
<!--<hook event="CUSTOM" subclass="conference::maintenance" script="catch-event.lua"/>-->
</settings>
</configuration>
其中
<param name="xml-handler-script" value="user_auth_xml.lua" />
<param name="xml-handler-bindings" value="directory" />
指定使用 user_auth_xml.lua 优先获取分机配置.
包括分机注册,拨打鉴权验证等获取分分机配置信息.
2. user_auth_xml.lua 脚本

如果要使用数据库, 自行取消注释并修改.
当前使用的是 从 scripts/users.txt 文件中 读取 分机号码 和 密码(空格分隔,每行一个分机).
scripts/users.txt 文件中没有配置 分机号和密码时,将会自动到xml 配置中去查找.
即: 此 lua 脚本 优先于 xml 配置文件执行, XML_STRING 变量为 nil 时就去查找默认的xml配置.
当前使用的是 1.10.3 版本测试的, 较低的版本可能要执行第三步,如下
3. 更改 conf/directory/default.xml 使 其配置的分机配置失效
红色 框里的 注释或者删掉
我用 1.10.3 版本, 不删也可以, 其他版本未测试, 更高的版本 应该也不用删掉的
不删的话, lua 脚本中 XML_STRING 变量为 nil 时就去查找默认的xml配置
