[Freeswitch-users] Putting CDR's together

I'm using hangup_complete_with_xml=true and export,hangup_complete_with_xml=true to generate my CDR's and I get my CDR's from the hang-up body variable. I can't find anyway to put them together. What UUID is the tie together UUID? I see call-uuid works if it's only 1 A and one B but if you have limit or something that rejects the B and then next bridge fires the Call-uuid doesn't match. Thanks for any help
