Hello,

i'm trying to call an extension, to normalize the called number to FR format, needed by an external operator SIP trunk, using the sip_req_user variable, and set a variable iv_dest_number to bridge the call using the normalized dest number.
I'd like to use extensions to split a big dialplan, and make my configuration more readable.

I'm quite confused by the way the regex is returning the $1 variable inside this extension : ARRAY
This same code is working without problem inside the main dialplan.

What am i doing wrong ?
What would be the best way to do that ?

Thanks with anticipation for any advice

Extension :
    <extension name="N_called_FR">
        <!-- All numeric and non empty called number                    -->
        <condition field="${sip_req_user}" expression="^\+?(\d+)$" break="on-true">
            <condition regex="any">
                <!-- Called number in FR format                          -->
                <regex field="${sip_req_user}" expression="^0(\d{9})$"/>
                <regex field="${sip_req_user}" expression="^33(\d{9})$"/>
                <regex field="${sip_req_user}" expression="^\+33(\d{9})$"/>
                <regex field="${sip_req_user}" expression="^0033(\d{9})$"/>

                <action application="set" data="iv_dest_number=0$1"/>
            </condition>
        </condition>
    </extension>
