Questions regarding CDR Logs

[Jordan Rudess]

- What does the “globalCallID_callManagerId” actually represent?  We assume it is the ID of the Publisher or Subscriber, is this correct?

- Why would some Pubs/Subs  output data to the CDR logs and others not output CDR log data?  For example, we might have CUSTOMER A and they have a publisher and 4 subscribers, and we see 5 “globalCallID_callManagerId”’s in the CDR data, but CUSTOMER B might have the same # of Pubs/Subs and we might only see 3 “globalCallID_callManagerId”’s in their data.  Why is this?

TIA,

Jordan

globalCallID_callManagerId is a unique Call Manager Identifier. Each Call Manager will have a unique globalCallID_callManagerId.

globalCallID_callManagerId relates to the CCM where the originating call leg was initiated.

Thanks for the response so far! I think I need to rephrase my first question a bit. A Cisco Cluster can have many “globalCallID_callManagerId” ‘s, so what determines how many “globalCallID_callManagerId” ‘s  show up in the CDR log files?

Thanks again!

I think it depends on the CUCM version. If I remember well:

With CUCM 4.x, any server running the CCM service has one “globalCallID_callManagerId”

With later versions, any CUCM server has one “globalCallID_callManagerId”

Hi Jordan,

A couple of things come to mind here;

Check if the CDR Enabled Flag is enabled in CallManager service parameters. Also

maybe there are no phones registered to the 4th and 5th CUCM's in your second

scenario.

This is an excellent doc

Thanks for your reply! So would it be safe to assume (in my 2nd question) that there could simply be a subscriber that may be doing, just as an example, performing as an auto attendant and nothing more - and that would be the reason for the lack of globalCallID_callManagerId's in the CDR? I haven't gone this far in configuring yet (test lab) so I'm not 100% sure if that's what could cause this.

Thanks again!

Hi Jordan,

You are most correct my friend

If a Sub is not generating call records you won't see

the globalCallID_callManagerId's in the CDR's.

Cheers!

Thank you very much for  your responses/help!

PS - I noticed your avatar - grats to Iginla for yet another 30 goal year. And I hope my Flyers can get out of this slump fast - what a horrific past few games .
