Hi, yes we have a block of DIDs, externally you would dial 2802002 and the gateway will send to the PBX 2002 which is the extension number. Then the PBX should decide if 2002 is allowed to get the call or it should present an IVR with an error message. Thanks.

Try something like this:
Add the variable in the user XML configs like you did. In this example we'll use:
<variable name="allow_incoming_calls" value="false"/>

I'm not sure how you route the incoming DID block, but you could do something like this in your public.xml file or in a file in conf/dialplan/public/:
<extension name="Routing Inbound DIDs">
  <condition field="destination_number" expression="^(280(20\d\d))$">
    <action application="set_user" data="$2@${domain}"/>
    <action application="transfer" data="$1 XML default"/>
  </condition>
</extension>

Then near the top of default.xml you could do something like this:
<extension name="Handle inbound exceptions">
  <condition field="${allow_incoming_calls}" expression="^false$"/>
  <condition field="destination_number" expression="^280(20\d\d)$">
    <action application="log" data="INFO Call to extension $1 being routed to IVR"/>
    <action application="ivr" data="my_ivr"/>
  </condition>
</extension>

Naturally you'll need to build "my_ivr" or otherwise do something with the call. Standard disclaimer applies: I dropped this in off the top of my head so be sure to tinker with it if it doesn't work the first time. :)

How is the caller getting to the extension in the first place? Do you have a block of DIDs or is the caller dialing an ext at an auto attn?
