[Freeswitch-users] remove country code from destination_number

Hi, I'd like to have the country code "+49" removed from destination_number and changed to "0" I tried: <extension name="international" continue="true"> <condition field="destination_number" expression="^\+49(.*)"> <action inline="true" application="set" data="destination_number=0$1"/> </condition> </extension> but after correctly executing this extension-statement it reverts to the original version of destination_number
