Solved: Null Media Info in CAR CDR Report

Jason Neurohr · ‎01-19-2017

CUCM version 11.0.1.

When running the CAR, CDR > Search > By User/Phone Number/SIP URL. The Media Info value for all records is null.

All devices are TelePresence Endpoints running CE8.3.0 e.g. MX300/700/800 or DX80.

Does anyone know why this might be occurring?

Load CDR only is unchecked

CDR Enabled Flag is True

Call Diagnostics Enabled is Enabled Only When CDR Enabled Flag is True

I've attached a screenshot showing the issue

Thanks

Jason

Hi Jason,

unfortunately this is expected behavior. TelePresence end points do not report back call management records to CUCM.

You can read it here:

Just search for the key word "telepresence".

Please rate, if it helps.

Best regards

Igor

Hi Jason,

Is it happening for calls traversing a SIP trunk or for internal calls as well? Please check the following bug

Hey Manish,

Thanks for the reply. It could be this bug. The majority of calls will be to a conference on a TPS via a SIP trunk to Conductor. I'll need to test some point-to-point calls and see if the result is the same.

I'll post back to the thread with the test results.

Hey Manish,

It is not this bug unfortunately. Point-to-point calls also omit the Media Info.

Hi Jason,

Can you collect detailed callmanager service traces for a test call and check the SIP Bye message , the SIP Bye message contains the call related stats and we need to confirm if these are getting generated/printed in the callmanager service traces.

Hey Manish,

Igor seems to be correct and the TP/Video devices do not provide CMR data. There is no CMR detail in the SIP BYE.

Thanks for your responses also.
