[asterisk-users] How to tell if there is a transfer from CDR?

[Bryant Zimmerman]

On blind transfers I believe the two cdr's have the same unique id .  On attended transfers there is no real way I have found to address this issue. CDR's with transfers really suck the way they are right now. On blind transfers you can do some flagging of the second CDR by checking in your dialing contexts to confirm it is a blind transfer ${BLINDTRANSFER}. On attended transfers you are just out of luck. You have to sort them out with CDR's. This cost us some money with inbound toll free calls because we did not know this occurred this way for some time.

Last time I analyzed this (I believe back in 1.2) there was no way of
telling. However a blind transfered call would generate 2 CDR
recoreds:
1. For the part of the call with the transferrer and transfered.
2. For the part of the call with the transferee and transfered.
The call duration for the 2nd record would include the time of the 1st
record as well. So if part one took 20 seconds and part 2 40 seconds,
then the 2nd record would have 60 seconds as billable.
The only workaround was to check the BLINDTRANSFER var and reset cdr
if it was populated.

Please members of this list, I would love to hear more input as I'm
sure this has changed. Also I would not be surprised that I'm wrong in
my analysis as more than 4 years has passed since and I might have
forgotten.

TIA
