Hi,

${DIALEDTIME} - ${ANSWEREDTIME} isn't really a good measurment of the PDD, because it includes the time that the phone has been ringing. The PDD (post dialing delay) is the time that has been spent between the time at which asterisk received the call and the time the called party /starts ringing/...

What do you think?

Cheers,
Jean-Michel.
