Hello, I would like to record a call, with the date in the filename. A read that in condition i can use api function, but i can't use the result of the function, Is there any error in this extension? How could i solve this problem? <extension name="incoming"> <condition field="source" expression="mod_sofia"/> <condition field="destination_number" expression="^668$"/> <condition field="%{strftime} {%Y%m%d%H%M%S}" expression="^(.*)$"> <action application="set" data="datetime=$1"/> <action application="record_session" data="C:\freeswitch\record\${caller_id_number}_${destination_number}_${datetime}.wav"/> <action application="bridge" data="portaudio"/> </condition> </extension> Thanks, Tamas
