170.5. 基本配置 /etc/freeswitch/vars.xml

170.5.1. 默认密码

			
[root@netkiller ~]# cp /etc/freeswitch/vars.xml{,.backup}

随机产生密码

			
[root@netkiller ~]# randpasswd | cut -c -10
NLYPx9JjSx

修改默认密码，将 1234 改为

			
  <X-PRE-PROCESS cmd="set" data="default_password=1234"/>
改为   
  <X-PRE-PROCESS cmd="set" data="default_password=NLYPx9JjSx"/>

170.5.2. 领域

配置领域

			
<X-PRE-PROCESS cmd="set" data="domain=sip.netkiller.cn"/>

170.5.3. 公网IP地址

配置公网IP地址

适用场景，公网IP直接在Linux eth0 网卡上配置。

			
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=stun:stun.freeswitch.org"/>
改为
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=host:sip.netkiller.cn"/>
或
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=IP地址"/>

170.5.4. NAT 配置

前面的基本配置，是物理服务器网卡直接配置公网IP地址，很多云主机采用弹性IP机制，将公网IP映射到云主机上。这种模式就需要用到 NAT

配置方法还是修改 /etc/freeswitch/vars.xml 文件

170.5.4.1. 方案一

					
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=autonat:你的公网IP地址"/>
					
				

					
  <X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=autonat:121.37.25.251"/>
  <X-PRE-PROCESS cmd="stun-set" data="external_sip_ip=autonat:121.37.25.251"/>

170.5.4.2. 方案二

					
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=host:你的域名"/>
					
				

					
  <X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=host:sip.netkiller.cn"/>
  <X-PRE-PROCESS cmd="stun-set" data="external_sip_ip=host:sip.netkiller.cn"/>

170.5.4.3. 方案二

					
<X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=host:$${domain}"/>
					
				

					
  <X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=host:$${domain}"/>
  <X-PRE-PROCESS cmd="stun-set" data="external_sip_ip=host:$${domain}"/>

170.5.5. 编码

			
  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,G722,PCMU,PCMA,H264,VP8"/>
  <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=OPUS,G722,PCMU,PCMA,H264,VP8"/>

170.5.6. 控制台日志级别

			
<X-PRE-PROCESS cmd="set" data="console_loglevel=4"/>
或
<X-PRE-PROCESS cmd="set" data="console_loglevel=info"/>

样本参考

例 170.1. /etc/freeswitch/vars.xml

这是我的配置仅供参考
