Hi Peter,
From accounting point of view, the relevant timestamp is when the call starts and, from sip point of view, this is 200 OK.
But if from whatever reasons you want to account the timestamp for INVITE, use extra accounting (see acc module page). At INVITE time store in an AVP the current timestamp (use pseudo-vars for this) and set this AVP into extra acc.
regards, Bogdan

Hello All!
Right now OpenSER generates Acc-Session-Start when "200 OK" message arrives. I need to generate Acc-Session-Start exactly in that moment when INVITE received (I can't need to wait for answer from other side).
So how can I do it?
