here is an example.

extension agent_state is called with execute_extension like that:
<action application="execute_extension" data="agent_state XML features"/>



    <extension name="agent_state">
      <condition field="destination_number" expression="^agent_state$"/>
      <condition field="${agent_state}" expression="^(IDLE|EMPTY)$">

        <action application="set" data="origination_cancel_key=#"/>
        <action application="export" data="execute_on_answer_1=spandsp_start_dtmf"/>
        <action application="export" data="execute_on_answer_2=bind_meta_app 4 a s execute_extension::att_xfer XML features"/>
        <action application="set" data="transfer_ringback=%(2000,4000,425,0)"/>
        <action application="execute_extension" data="populate_xfer_dial_string XML features"/>
        <action application="att_xfer" data="${xfer_dial_string}"/>

        <anti-action application="set" data="transfer-digits=NULL"/>
        <anti-action application="eval" data="cancel transfer"/>
        <anti-action application="playback" data="tone_stream://%(500,500,425,0);loops=3"/>
        <anti-action application="set" data="api_result=${uuid_hold off ${uuid}}"/>

      </condition>
    </extension>


so, if destination_number is "agent_state" and if ${agent_state} variable is "IDLE" or "EMPTY" , perform actions else perform anti-actions




hope it helps.

Yes, I know this, Ken. The problem is with nested condition. Anti-actions in nested conditions are executed if parent condition fail? Also, I've
observed that even if parent condition fail, actions or anti-actions in nested condition is executed. Ie, nested condition is checked and if fails -
anti-action is executed, if it pass - actions is executed, regardless if parent condition fail or pass.

I expected that any actions/anti-actions in nested condition will be executed only if parent condition pass. Yes, wiki states that parent condition is
not checked until nested-conditions are not checked. But, if at the end parent condition fails, whole extension should not be executed.

For now I changed the conditions in a simple AND without nested conditions.
