example :

<extension name="blabla">

<condition>
<action application="set" data="test=cake"/>
</condition>
<condition field="${test}" expression="^(cake)$">
<action application="set" data="prfx=00"/>
</condition>
<condition field="${sip_to_uri}" expression="^(1\d{10,15})@$${domain}$">

<action application="set" data="getPrfx=${prfx}"/>

</condition>

</extension>

but ${prfx} is empty.

I'm almost sure I didn't understand FS vars scope yet....

Thanks
