[OpenSIPS-Users] $DLG_lifetime but in ms

[Marcin Groszek]

If you are not calculating the cost of the call in the script it self 
you may create external script to go over your acc table and use 
"ms_duration" to adjust "duration"

or use *$Ts**$Tsm *at the beginning of the call, save it to a dialog and 
compare it with same value at the end of the call, then round up and 
write to acc table and/or calculate cost of the call.
