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

Hi all
Question about an additional cdr information.
We need to get the pdd value – means a time value till the user gets a
ringback or an error- to track the delay, till a connection is done
àquality issue for customer.
5.6.1 Definition of Post Dial Delay
Post Dial Delay (PDD) is experienced by the originating customer as
the time from the sending of the final dialled digit to the point at
which they hear ring tone or other in-band information. Where the
originating network is required to play an announcement before
completing the call then this definition of PDD excludes the duration
of such announcements.
How can this be done in Kamailio?
We use the carrierroute module with different fallback carriers.
Kamailio version 3.3.5
Thanks in advance
Oli
