Cisco CDR time stamp and calabrio time stamp do not match with each other

[prathmesh.bhurke@i-karma.on]

I am facing issue with the reconciliation of WFM call records. It is not attaching all data of agent with the call. gives us error timestamp does not match. But this happens for some calls only. That is some random calls having this issue. Not sure why this is happening. 

We are using Network Recording with CUBE, 

WFM version:  11.5

UCCX version: 11.6

CUCM version: 11.5

We have a case open with both CISCO TAC as well with Calabrio, Case is going nowhere. Anyone have an idea regarding this please help.

Since it only happens on some calls and not all I would rule out Calabrio as the issue for the moment and focus on the Cisco side. I would start with the devices throwing the errors. Does it always seem to be the same devices that throw the error? Is the time off on the device itself? If the time on the device is ok, how about the CUCM pub/sub that the device is registered to. Is there a time discrepancy there?

I'd start by checking that all the devices have the correct time and are hopefully all getting their time from the same local NTP server.
