VNQM Not getting call stats-MOS, Jitter, etc

Hello, I have VNQM setup, have my CCM's installed and get the CDR's from CCM. I can see all the call records, but none of them display any statistical information for calls. I have IP SLA UDP VoiP Jitter operations between site routers but get nothing. Not even on calls in my main campus between 2 phones on the same LAN switch.

We only have the single CCM cluster, so all phones register and call control through this single cluster. What else needs to be done to be able to get these call statistics?

Thanks,

Mike

Then it could be caused by disabled generating of call quality metrics on Call Manager (it's disabled by default).

Check this on CUCM admin console: System -> Service Parameters, scroll to Cluserwide parameters, check Call diagnostics enabled

Hi Mike,

What kind of phones/gateways are you using in your network? Call quality metrics as a part of call information are provided only by MGCP gateways and SCCP phones. It doesn't matter, if IP SLA operation is defined or not.

Hey Bob, we have all SCCP phones, 7940, 7945, 7960. Our GW's are Cisco 3845's.. It doesn't matter if it is an internal call phone to phone, or an external call through a GW. It just shows as N/A under all the statistics.

Thanks Bob, that seems to have worked for most calls. I figured it was something like this but could not find any reference.
