Yes, they are mostly locally registered users. The groups are defined like

      <group name="group1">
        <users>
          <user id="1001" type="pointer"/>
          <user id="1002" type="pointer"/>
        </users>
      </group>

Some users are associated with external numbers:

<include>
  <user id="external_user">
    <params>
      <param name="dial-string"
value="[toll_allow=local]loopback/XXXXXXX/default/XML"/>
    </params>
    <variables>
      <variable name="user_context" value="default"/>
    </variables>
  </user>
</include>

if that matters.
