Hi,
 
day after I undertand a littlee more all these xml hell files (not friendly to read ;)),
but to be a PERl developer since 1999 understand regex and PERL language make life more easy...
However, I don't understand yet the concept of internal exterenal.
is it for phone registration AND outbound calls ?
for now I try to make an external call from 1000 ext (registered on port 5060)
so I added an extension in dialplan/default.xml
 
    <extension name="outbound_europe">
        <condition field="destination_number" expression="^00?(\d+)$">
              <action application="bridge" data="sofia/gateway/myprovider_europe/00$1"/>
        </condition>
    </extension>
so if call starts with "00" it redirects to my provider that manage outbound calls, is it correct ?
I put the myprovider.xml account into sip_profiles/external/myprovider.xml.
 
Thanks for your help
