beaglebone-asterisk应用笔记

前言

问什么是用这个系统呢？之前说的要做一个SIP系统服务器，用来测试IP Recorder应用。之前使用Raspberry PI已经可以顺利运行了。接下来用BeagleBone-Black来实现一下这个功能。

准备

1. 一块BeagleBone-Black板子；
2. 一块4G的Micro-SD卡；
3. 有线网络或USB网卡

安装系统

下载beaglebone-asterisk镜像文件

由于我使用的旧版本的BBB，所以我尽量下载低版本的镜像文件。我下载的是
[raspbx-bbb-28-05-2013.img.xz]http://beaglebone-asterisk.raspbx.org/download/raspbx-bbb-28-05-2013.img.xz版本。

解压镜像包

该镜像包可以通过7Zip软件进行解压。该软件可以通过google或baidu进行搜索下载。

烧录镜像文件的Micro-SD卡

通过Win32DiskImager烧录到Micro-SD卡。

运行

将Micro-SD卡插入到BBB的卡槽，给BBB上电，OK了，系统开始运行了。

运行raspbx系统

系统上电后，查找到raspbx的IP地址，在浏览器中输入相应地址，可以看到freePBX的界面。

启动wifi配置

root@raspbx:/# ifup wlan0
ifup: interface wlan0 already configured

查看wifi连接状态

root@raspbx:/# ifconfig
