[Freeswitch-users] Billsec in dialplan

Hi, Is it possible to access ${billsec} in the dialplan after the bridge application (having hangup_after_bridge=false)?? I want to log the billsec but currently it is always empty. I have a workaround in a test server using api_hangup_hook to call a lua script with session_in_hangup_hook=true, and inside the lua script I can access the billsec variable and thus write it to the logs. Is there no way to do this within the XML dialplan? Thanks! Best regards, Joel.
