[SR-Users] Acc INVITE dialog start timing difference

[Dirk Teurlings - Signet B.V.]

Hi,

I'm seeing a difference in timestamp for acc modules recorderd INVITES
and the dialog start event.


This is the log entry:
Apr  1 12:55:59 host /usr/sbin/kamailio[15642]: INFO: <script>:
5d3ff3407b9761b24c4f75195c6ccb1d at 192.168.10.245:5060 - dialog:start

And this has been added by ACC in the database:
INVITE
as2880319e
56FE53B9-49E3774-3E86ED1B
5d3ff3407b9761b24c4f75195c6ccb1d at 192.168.10.245:50...
200
OK
2016-04-01 12:56:01


Why are these two seconds apart? Shouldn't the acc module record the
same dialog start event time as the start of a dialog? When I look at
the value of DLG_lifetime this confirms my findings, as it results in:
dialog_time = TS - dlg_start

When looking at the database BYE-time - INVITE time, the call is two
seconds shorter.

Any insight would be appreciated!
Cheers,
Dirk
