Hello, another addition to the dialog module is the new pseudo-variable class $dlg(...) http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#dlg_attr With it you can get access to all attributes of current processed dialog, e.g., caller and callee URI, start time, flags... A typical use case is to write full cdr when the BYE comes over - the dialog stores the start time and you can get the end time via $Ts. You can either write the acc record at dialog ending or update the start acc event written when INVITE was processed - you have access to the call-id, from tag and to tag in the right order and one shot of sql_query() will do it. Cheers, Daniel
