Asterisk CDR Report

I need PHP script which which extract the following details from my Asterisk CDR for any given DID which is being stored in `userfield`. > Date-Time > DID (I am recording this is `userfield`) > CLID > t1 (time when call was received) > t2 (time when call was answered by agent) > t3 (time when call was hung-up) > t4 (Hold time: t2-t1) > t5 (Talk time: t3-t2) Fancy HTML etc is not required. Just simple tabulation will do. Call Flow: ========== [caller] -> [Trixbox IVR] -> [Trixbox Call Queue] -> [Trixbox Human Operator] I can send a sample of about 100-200 records from my CDR.
