[Freeswitch-users] lua script after transfer to conference

I have a Lua script that get the conference_member_id and then passes it to a DB. FS wont give me a member_id until I transfer the call to the conference and once I transfer the call to the conference the script stops execution until the user hangs up. How can I get the lua script to continue execution even after I transfer a call to the conference? I have session:execute("conference", 3001); userId = session:getVariable("conference_member_id") Thanks
