[Freeswitch-dev] Conference CDRs via http

[Seven Du]

Any update on this? 

How about just fire a SWITCH_EVENT_CDR  with raw event headers so mod like mod_cdr_pg_csv can listen to it and write to db without parsing back the XML?

Thanks.

The advantage for this solution is that everything related to this mechanism is included in this module. Drawback: if something in mod_xml_cdr requires fixing or extending, probably the same changes should by applied in related parts of mod_conference.
