[OpenSIPS-Users] CDR Accounting

[Anton Zagorskiy]

Hi Dave.

> So just to be sure I'm clear on this. $Ts rounds down ( truncates ) the
current second. So using $avp(s:start_time) = $Ts.$Tsm; would give something
like "12343253.543233" and always be accurate?

You should understand that $Ts.$Tsm is two independent calls to the system
time function. So actually $Tsm isn't microseconds of $Ts.

P.S. Could you please use any brackets to mark original letter or send your
answer in the plain text fromat?

dialog variable like $dlg_val("start") = "$Ts.$Tsm" at start
and $dlg_val("answered") = "$Ts.$Tsm" at answer and at the end of the call
add them db_extras > along with $Ts.$Tsm for the end of the call. You would
then want to go off of those numbers rather than what the acc module
automatically put in the db.

times but you would still have the benefit of not having to have an external
process building cdrs from acc table matching up BYEs to INVITES, etc.

work with non integers. But you could do that easily with a sql trigger on
the record insert.
