[Freeswitch-users] dialplan - expression matching and variable - 2nd try

Hi all, sorry for the first message, I hit the wrong keys an Outlook sent the message...once again: why is the following not working: <condition field="destination_number" expression="^(500)$|^(600)$"> <action application="set" data="dialed_number=$1"/> <-- $1 is empty when using the above expression, $1 is empty. If I do it like this <condition field="destination_number" expression="^(5\d\d)$|^(6\d\d)$"> <action application="set" data="dialed_number=$1"/> <-- $1 is empty It's working. I don't understand why. Thanks in advance and best regards, Stefan
