[SR-Users] Dialog Module - how???

[Ovidiu Sas]

For CDR purposes, the duration of a call is for how long that call was
in conversation, which is reflected by $DLG_lifetime:
http://www.kamailio.org/docs/modules/3.1.x/modules_k/dialog.html#id2745926
There's no need for 'fancy' duration computation like $var(elapsed) =
( $Ts - $dlg(start_ts) );
