应朋友要求做了个简单的测试，花费时间不过半小时，记录如下：

OpenSIPS IP 地址：192.168.31.213

FreeSWITCH IP 地址：192.168.31.166

加载 uac_registrant 模块（这个模块依赖 uac_auth 模块，得先加载），向 FreeSWITCH 注册

先插入数据：

INSERT INTO registrant (registrar, aor, username, password, expiry, binding_URI) VALUES ('sip:192.168.31.166', 'sip:1001@192.168.31.166', '1001', '1234', 3600, 'sip:1001@192.168.31.213');

启动 OpenSIPS

fs_cli -x 'show registrations as xml' 得到的是：

<result row_count="1">
  <row row_id="1">
    <reg_user>1001</reg_user>
    <realm>192.168.31.166</realm>

    <network_proto>udp</network_proto>
    <hostname>DESKTOP-QEPDSM1</hostname>
    <metadata></metadata>
  </row>
</result>

fs_cli -x 'sofia global siptrace on'
