为何要研究freepbx呢，之前研究了asterisk 17，当时创建分机，是在配置文件里面完成的。存在一个问题，那就是每次创建分机后，或者改动配置后，都需要重新启动应用，才能生效，这个会影响线上的业务。于是转而研究动态加载的方案，原生的asterisk方案里面有realtime技术，这个非常灵活，但是呢，就是因为太灵活，需要学习的东西，基本都是底层的，比较难一时半会弄清楚。
于是选择freepbx作为替代产品，freepbx产品是包装asterisk的一款产品，安装非常方便，配置是图形化的界面，每个配置项有相对明确的解释，支持国际化，想看那个语言就那个语言，当然，我们看中文就好了。
我这里安装采用的是ISO版本安装，从freepbx官网（https://www.freepbx.org/）下载的，V15版本。
安装非常方便，可以在一台裸的物理机上，像安装操作系统一样的安装，也可以通过VMware，基于虚拟机内安装。置于怎么安装，这里不做介绍，自己可以去网上找资料学习如何安装操作系统即可。我这里是基于VMware的虚拟机实现的安装。这里要介绍的是网络的问题，因为我再Win10的机器上，安装VMware，虚拟出了一个机器（2C2G30G），安装freepbx大概花了10分钟吧，不用费什么劲。
我的虚拟机和我的宿主机之间是通过NAT通信的，这里配置的过程，简单说下：
1）在freepbx的系统里面，将默认的IP分配机制由DHCP调整为static。为何这么做呢？这里主要考虑到方便后续建立分机号对应的AOR，Endpoint等对象数据的一致性，不至于出现机器IP变化了，而asterisk对应的pjsip的对象没有变，导致不必要的错误。
TYPE="Ethernet" PROXY_METHOD="none" BROWSER_ONLY="no" #BOOTPROTO="DHCP" BOOTPROTO="static" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_FAILURE_FATAL="no" IPV6_ADDR_GEN_MODE="stable-privacy" NAME="eth0" UUID="b75f1df9-9b30-4e00-8f9a-5e96a07dd5e1" DEVICE="eth0" ONBOOT="yes" IPADDR="192.168.38.129" NETMASK="255.255.255.0" GATEWAY="192.168.38.2"
2）将Win10机器的对外上网的网卡共享给VMware8，方便虚拟机通过Win10宿主机访问外网
具体的操作流程，请参考图中的编号，体现了操作的顺序，完成4的步骤后，点击确认即可。
配置完后，在freepbx的虚拟机上，ping宿主机，以及从宿主机上ping下freepbx宿主机，若双方都能ping通，说明没有问题了。若有问题，ping不通，则可能需要将虚拟机的network重启一下（service network restart）。
或者将宿主机上的VMware8网络节点禁用启用一下，如下图（选择VMware8，点击鼠标右键，选择禁用，然后再启用，即可）
在完成了freepbx的安装和基本的网络配置后，我们就需要验证一下基于freepbx的简单实用了。这里，我创建两个分机10001和10002，这两个电话之间进行互打电话。
1）建分机
step1：
在“通信接口连接”里面选择“分机”，或者英文界面时，“connectivity”---》“Extensions”。
step2：
然后，选择上图中的1或者2任何一个入口，都可以进入进行pjsip的分机的创建。这里没有选择chan_sip，而是chan_pjsip，因为pjsip相对来说模块更独立，性能相对更好。
step3：
按照上图中的编号，填写相关的内容，最后按照6指示，提交保存。
step4：
创建完分机后，准备打电话，在yateclient上配置上10002这个分机，发现无法认证，认证过程失败。这个是为什么呢？
上面截图是freepbx后台显示的日志，认证失败
分析了很久，然后在freepbx的官方网站上看到操作步骤里面，每一步操作，只要涉及到数据配置的变更，都强调了点击“Apply Config”，即下图所示的红色的按钮。
我也点击了这个按钮后，然后再拨打电话，还的确就是这个问题，因为没有“更新配置”，页面上修改的配置，并没有触发后台系统的相关Endpoints的表结构中去让其生效，可以通过命令行，在系统查看当前系统的Endpoints的信息进行确认当前的Endpoints中是否有你想要的，若么有，就需要考虑这个“更新配置”按钮是不是没有点击。
其实，在freepbx的操作界面上，也可以查看当前asterisk系统下的pjsip的Endpoints信息的，请看下图（先点击1，然后在2对应的框中，输入“pjsip show endpoints”，最后回车即可）：
2）打电话
在基于yateClient的工具进行拨号，在本地启用两个yate客户端，一个作为10001的终端，一个作为10002的终端。拨打电话界面效果如下图
从这个图，很清晰的可以看出，电话是从10002的分机拨打给10001这个分机的。此时，点击Accept按键，即可接通电话。（细心的小伙伴，可能会说，打电话和接电话怎么在一个截图里？呵呵，我这里是在模拟，在同一台机器上完成的通话）
再看看后面的日志，清晰看看通话的asterisk的逻辑：
