1、/etc/freeswitch/autoload_configs/switch.conf.xml

<param name="switchname" value="Root.Lee.Sofia"/> 
<!--系统“主机名”注册时显示的HOST及进入fs_cli后显示的主机名-->

如下："freeswitch@Root.Lee.Sofia"不再显示操作系统主机名，同时"Host:"显示名称也不再显示主机名

freeswitch@Root.Lee.Sofia> sofia status profile internal reg

2、/etc/freeswitch/sip_profiles/external.xml internal.xml

<param name="user-agent-string" value="Root.Lee.Sofia"/> 
<!--SIP信令中显示的user-agent，默认是FreeSWITCH＋版本号-->

如下：发送出去的INVITE消息里面包含的User-Agent: 名称改变

   ------------------------------------------------------------------------
   SIP/2.0 200 OK

3、源码./src/mod/endpoints/mod_sofia/sofia.c

if (!profile->sdp_username) {
profile->sdp_username = switch_core_strdup(profile->pool, "FreeSWITCH");
}  
#修改此处"FreeSWITCH"可修改SIP消息SDP的FreeSWITCH标识，这个文件有几处"FreeSWITCH"，均是显示，名称的，可以一并修改
#修改后需要重新编译sofia模块，并将编译出来的"mod_sofia.so"复制到FreeSWITCH相应的库文件位置


如下：SIP消息SDP中”o=******      s=******“不再显示"FreeSWITCH"

   o=Root.Lee.Sofia 1500262855 1500262856 IN IP4 172.16.100.229

   s=Root.Lee.Sofia

   t=0 0
   m=audio 32756 RTP/AVP 0

   a=ptime:20

4、SIP消息头中不带号码而是显示FreeSwitch问题，如下：

INVITE sip:7999@172.16.100.240:5060 SIP/2.0
Via: SIP/2.0/UDP 172.16.100.247:5080;rport;branch=z9hG4bKNvrZg7ZS0393e
Max-Forwards: 69
From: "ligen" <sip:FreeSWITCH@172.16.100.240:5060>;tag=66Sm8SUjvc4pp
To: <sip:7999@172.16.100.240:5060>

当送出的INVITE中From字段显示的是“FreeSWITCH@ip:端口”时，需要在网关中添加

<param name="caller-id-in-from" value="true"/>

否则，可能对端显示号码是88888888（华为呼叫中心就是这样子的）。
