[Freeswitch-users] transfer_fallback_extension

On a number of websites and in my conf/directory/default.xml file I see: <variable name = "transfer_fallback_extension" value = "operator"/> And in my conf/dialplan/default.xml file I see <extension name = "operator"> where the operator 'extension' is defined as a single extension number. But I don't want the failed transfer attempt to go to a single pre-defined extension I want the failed transfer attempt to go back to the extension which initially launched the transfer attempt How/where would I modify the variable transfer_fallback_extension to get this to work as needed? Or should this be handled in a different manner somewhere else within FreeSWITCH? If so, where/how? Thanks
