Centos7 公网安装freeswitch1.10.2 阿里,腾讯,华为等云服务器均因nat失败
一. FS NAT穿透问题
团队自己写的WebRtc网页,用来做呼叫中心。私有网络: 怎么都能通。公网: 软电话经过nat穿透可以通话,但是webRtC网页端不可以,原因: sip拨号成功,但所有RTP包都发给了云的私网地址，通不了。而后，再看SDP，服务器发过来的就是私网地址， 网上基本都是说设置ext-rtp-ip和ext-sip-ip为公网地址就可以，还有其他各种配置文件, 但没有效果！
只能剑走偏锋, 技术搞不定,寻找硬件。条件缺一不可:
1.有公网IP
2.公网IP与私网IP必须为同一个
3.具备和私网相同的环境
二.云服务器寻找
市面上主流的云服务都试过了,无一例外都失败了,还克了许多金,心疼.到此不得不夸一下三丰云厂商.(跳转链接)免费试用,关键是满足以上需求,牛。服务器找到了开干!
三.搭建FS
1. 环境要求
操作系统：64位的centos7.9 (厂商最高提供7.6,需要手动update)
Freeswitch版本：freeswitch1.10.2
检查网络的连通性：能正常访问外网(ping www.baidu.com)
2.依赖包
x264
libks
signalwire-c
libav
可在官网下载,这里我提供所有的依赖包: 点击下载
3.关闭防火墙相关操作
CentOS7防火墙设置,关闭SELinux和端口相关操作

FS 基本操作命令
# 后台启动freeswitch服务
freeswitch -nc -rp
freeswitch -nonat -nc -rp //不检查路由穿透行，加上此参数后会启动很快
freeswitch -stop
fs_cli
# freeswitch -help
-help -- 显示本帮助信息
-version -- 显示版本信息
-rp -- 开启高优先级（实时）设置
-nosql -- 不使用SQL，show channels 类的命令将不能显示结果
-nonat -- 如果路由器支持uPnP或NAT-PMP，则FreeSWITCH可以自动解决NAT穿越问题。如果路由器不支持，则该选项可以使启动更快
-stop -- 关闭 FreeSWITCH，它会在run目录中查找 PID文件
-nc -- 启动到后台模式，没有控制台
