Actions are all run AFTER all conditions are parsed so the nated var is not set yet.  you can do a single condition in this case, and set nated for use elsewhere if you need it in the actions.

Hi Guys,

I'm trying to do some string matching against a created var and looks like I am doing something wrong but I can't find whats it.

I'm wrote an extension just for tests purposes on dialplan/default.xml:

<extension name="nat_detect" continue="true">
     <condition>
        <action application="set" data="nated=${cond(${network_addr} != ${sip_contact_host} ? 1 : 0)}"/>
     </condition>
     <condition field="${nated}" expression="1">
       <action application="log" data="Action=${nated}"/>
       <action application="set" data="proxy_media=true"/>
       <action application="set" data="sip_nat_detected=true"/>
       <anti-action application="log" data="Anti-Action=${nated}"/>
     </condition>
</extension>

Using two SIP extensions (1000 and 1001) behind NAT and I expected too see "Action=1" on the logs/console, but I'm seeing "Anti-Action=1".

I really appreciate any inputs.
I'm using FS 1.0.3 stable.
