然后整个拨号计划都包含此扩展名：
<context name="default">
<extension name="SignalWire CONNECTORS incoming call">
<!-- the number you assigned in your dashboard -->
<condition field="destination_number" expression="^(\+19162510217)$">
</condition>
</extension>
</context>
在fs_cli上确认：
freeswitch@tr2> xml_locate dialplan
<section name="dialplan" description="Regex/XML Dialplan">
<context name="default">
<extension name="SignalWire CONNECTORS incoming call">
<condition field="destination_number" expression="^(\+19162510217)$">

</extension>
</context>
</section>
但是在检查传入事件时，有一个CHANNEL_EXECUTE事件（和一个匹配的CHANNEL_EXECUTE_COMPLETE事件）表明transfer应用程序已执行。这是一个差异（点击“运行代码段”以查看它）：
