[SR-Users] pdd value

[Daniel-Constantin Mierla]

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
