用下面方法查看密码
[root@netkiller ~]# cat /etc/freeswitch/vars.xml | grep default_password
YOU SHOULD CHANGE THIS default_password value if you don't want to be subject to any
<X-PRE-PROCESS cmd="set" data="default_password=eFo1zKZyS2wcZ3KG"/>

NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE
FreeSWITCH works off the concept of users and domains just like email.
You have users that are in domains for example 1000@domain.com.
When freeswitch gets a register packet it looks for the user in the directory
based on the from or to domain in the packet depending on how your sofia profile
is configured. Out of the box the default domain will be the IP address of the
machine running FreeSWITCH. This IP can be found by typing "sofia status" at the
CLI. You will register your phones to the IP and not the hostname by default.
If you wish to register using the domain please open vars.xml in the root conf
directory and set the default domain to the hostname you desire. Then you would
use the domain name in the client instead of the IP address to register
with FreeSWITCH.

有一组号码，他们可能在通话，你希望终止他们的通话，接到自己这边来，可以使用，代接电话功能。
确认代接电话拨号规则已经配置 /etc/freeswitch/dialplan/default.xml
<extension name="global-intercept">
<condition field="destination_number" expression="^886$">
<action application="answer"/>
<action application="intercept" data="${hash(select/${domain_name}-last_dial_ext/global)}"/>

创建一组用户 callgroup 相同，此处的 callgroup 与 组呼叫 没有任何关系，callgroup 是指代接电话组。
[root@production default]# cat /etc/freeswitch/directory/default/177.xml
<include>
<user id="177">
<params>
<param name="password" value="0848"/>
<param name="vm-password" value="0848"/>

<variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/>
<variable name="callgroup" value="bg7nyt"/>
</variables>
</user>

配置好后，你可以找几个电话测试，拨通一组后，用另一部话机不通 886 就能接管正在通话的号码。
