Hello,
in the request route, for initial invite you can store $Ts in an avp, like:
$avp(itime) = $Ts;
before relaying, set an onreply_route for the transaction and then in
onreply route, get the value like:
if(status=="180") {
$avp(pdd) = $Ts - $avp(itime);
}
In acc, you have to save the $avp(pdd).
Cheers,
Daniel
