Would appreciate it if someone could explain how to tell if a call in the CDR dump is a transfer and where did the transfer go to (phone number).
Thanks,
paul.

You can check on CDR report based on last redirect number.
Pls rate if its “Helpful”. If this answered your question pls click “Accept as Solution”.

So for an inbound call if last redirected number is not = to called number then it is a transfer?
Thanks,
Paul.

It depends on how you are defining "transfer". For instance, if you have a (1) call come in to your DN and you answer it, the last redirected number will be your DN and it will be a normal call setup. If you have the (2) call come in and go to your DN, which then goes to VM because you didn't answer it, the last redirected number will be your voicemail pilot. Technically this is a transferred call as it was transferred from your DN to the VM pilot. However, you can also define it as a (3) call that you answer on your DN, put on hold, hit the transfer button, then transfer to another DN such as your manager.
In your CDR, you will see #1 as "Incoming", #2 as "Tandem", and #3 as "Incoming". You will also see #1 and #2 as "Normal call clearing", whereas #3 will show as "Call Split" for the original inbound call leg, and "Normal call clearing" for the transfer leg. That leg will show where the call was transferred to.
You can find more information under "Transferred Calls" in this document: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/service/11_5_1/cdrdef/cucm_b_cucm-cdr-administration-guide-1151/cucm_b_cucm-cdr-administration-guide-1151_chapter_0100.html

As mentioned, last redirect number is a good way to see what number transferred the number.
A more complicated way would be to look at the globalCallID_callId and origLegCallIdnetifier and attempt to correlate them.
You could always use a free tool like VoIP Detective to process your CDRs - it will tell you if / where the call was forwarded.
