`<action application="export" data="execute_on_answer=record_session ${caller_id_number}-${destination_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.mp4"/>` 是一段FreeSWITCH配置代码,用于将通话录制为MP4格式。该代码中使用了`export`应用程序,它用于将一个变量导出到FreeSWITCH的全局变量中,以便其他应用程序可以访问它。
在这个代码片段中,我们使用了`execute_on_answer=record_session`应用程序来自动录制会话,并将录制的文件保存为`${caller_id_number}-${destination_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.mp4`的格式。其中,`${caller_id_number}`是主叫号码,`${destination_number}`是被叫号码,`${strftime(%Y-%m-%d-%H-%M-%S)}`是当前日期和时间,用于给录制的文件命名。
请注意,要使用MP4格式录制会话,您需要在FreeSWITCH中启用mod_avcodec模块,并安装适当的编解码器,例如libx264。希望这可以帮助您!

freeswitch execute_on_answer=record_session
`execute_on_answer=record_session`是FreeSWITCH中的一个应用程序,可以在通话接通时自动录制会话。使用`execute_on_answer=record_session`应用程序,您可以在通话开始时自动启动录音,并在通话结束时自动停止录音,从而轻松记录通话内容。
要使用`execute_on_answer=record_session`应用程序,您需要在呼叫路由中将其添加为呼叫路由模式的一部分。以下是一个示例呼叫路由:
```
<extension name="record_call">
<condition field="destination_number" expression="^100$">
<action application="answer"/>
<action application="execute_on_answer" data="record_session /path/to/recordings/${strftime(%Y-%m-%d-%H-%M-%S)}_${uuid}.wav"/>
<action application="hangup"/>
</condition>
</extension>
```
在这个示例呼叫路由中,我们定义了一个名为`record_call`的扩展,并使用正则表达式`^100$`匹配目标号码。当呼叫到达并匹配到此路由时,FreeSWITCH会自动应答呼叫并开始录制会话,录制的文件将保存在`/path/to/recordings/`目录中,并使用当前日期和时间以及唯一标识符进行命名。
请注意,`execute_on_answer=record_session`应用程序可以与其他应用程序一起使用,例如`play_and_get_digits`或`say`,从而实现更复杂的呼叫路由。希望这可以帮助您!
export PATH=$PATH:$CATALINA_HOME/bin
This command appends the path of the "bin" directory within the "CATALINA_HOME" directory to the existing "PATH" environment variable.
The "PATH" environment variable is a list of directories that the operating system searches for executable files when a user types a command in the terminal. By appending the "CATALINA_HOME/bin" directory to the "PATH" variable, the system can find and execute the scripts and commands stored in that directory without requiring the user to specify the full path to the executable file.
The "CATALINA_HOME" directory is typically used in the context of Apache Tomcat, which is a popular open-source web server and servlet container. The "bin" directory within the "CATALINA_HOME" directory contains the scripts and executables required to start, stop, and manage the Tomcat server.
By adding the "CATALINA_HOME/bin" directory to the "PATH" variable, the user can run Tomcat commands and scripts from any directory in the terminal without having to specify the full path to the executable file.
