[cisco-voip] CDR Record for transferred call question

transferred calls CDRs are a pain. and a possible toll fraud vehicle if not monitored/audited. 

take for example, extension 1234 calls an LD number then transfers to extension 4567. 

unless you track the transfer, the call is not logged properly. questions do arise, if you can track the transfer who do you charge? 1234 or 4567? 

i know this doesn't help, but i would hope that CallManager CDRs would keep the same callLegIdentfiers when necessary.

I am working with ISI Infortel, and having issue with reporting on 
transferred calls. They are saying that in the CDR flat files 
generated that the following fields should match up across all the 
call legs involved in a transfer. 

origLegCallIdentifier and the destLegIdentifier fields should match 
across the call legs. 

In the CDR file, there are 3 legs part of the transferred call and the 
origLegCallIdentifer field matches on the 1st and 3rd leg but is 
different on the 2nd leg which is the phone that transferred the call 
to the final phone. This is on Call Manager version 5.1.1 and I've 
also compared against same sample call flow on version 
and 7.0(2) and the CDR flat file records look the same. I've also 
tested with transfer softkey for the whole call flow and using hold 
and new call then transfer and the CDRs look the same so the method 
used doesn't effect the CDRs it appears. 

According to Cisco docs, it seems like it is working as it should as 
the examples in the docs match what I see and descriptions in the 
Cisco CDR PDF describe how these get generated, etc. But there is a 
section of the PDF that has the following for both of these fields, 
"If the leg of a call persists across several sub-calls, and 
consequently several CDRs (as during a call transfer), this value 
remains constant." which I don't understand what it means if these 
fields are different in the CDRs. I've opened a TAC Case and they 
confirmed everything is working as it should but the vendor is going 
back to this statement and states the fields should match up across 
all call legs so they can match up all the call legs for the report 
involved in the transferred call. 

The PDF is here, 


Just wondering if anyone else has ran into this before or not.
