[Freeswitch-users] Mod_xml_cdr BLeg Account Code

Anyone have any suggestions on obtaining / setting the Account Code for BLeg for Mod_xml_cdr. I applied accountcode but that is only handling for ALeg. I also looked at effective_caller_id_number - but I need to dynamically (at time of bridging a-leg to b-leg) define the accountcode? Probably some custom coding I would assume to pull this off. Any thoughts. Thanks
