I am running CUOM 2.2 and on the Service Level View, we see that the Phone count is 0. We have about 2000+ Phones that are registered with the Call Manager. What is really the issue here?



CUOM does a snmpwalk on ccmphonetable to check the number of registered phones. Do a snmpwalk on ccmphonetable (.                and check if you are seeing the registered phones.

If you do not see any phones, restart the SNMP Service on the call manager.

Hope that helps.


Hello Pari

We upgraded the OM from 2.2 to 2.3. After the upgrade, we could not open the application.

Can you help us with this?

Thanks -

Open the Install logs from the C: folder for OM 2.2.

Note down the BUILD_ID that you see there. If it is  "BUILD ID NT_CUOM2_2_CS32_20090715_1306", then the only option is to uninstall OM completely and then reinstall it.

This is bug "CSCtd72592".

Any upgrade from this build would cause more issues.

Please make sure you take a backup of the license file and then do a fresh install of OM 2.3.



I have a CUOM version 2.3 with Service Monitor and I am sending the CDRs and CMRs from CUCM version 6.1 to the CUOM server. I have configured the billing server in CUCM and I am seeing the CDRs and CMRs in the CUOM server. I left this configuration during more than a month but I can´t see CVTQ reports in the server and the status is "discarding data". What can I do to solve this problem and see CVTQ reports??

Thank you


Can you check if your CUCM and CUOM are synched to the same NTP Server ?  If the time difference is huge, then we discard the data and not process them.


Hi Pari

We have call manager running in China and US , when i am calling to China from US i am getting MOS value of 4.5 in China IP phone while MOS value of 2 in US IP phone, what could be the reason for this as voice quality is good on china side but not good at US side.Calls are travelling through our WAN network over Inter cluster trunks.


Hi Pari,

I have CUOM 2.3 and CUSM 2.3 and I have 6 CUCM clusters in the environment.  There seems to be a disconnect somehow between the CUOM/CUSM in receiving CDR data.  I will do a CDR search on a particular phone number and there will be some missing CDRs when I compare what CUSM gives as opposed to what is showing up in CDR Search in CUCM.  Can you explain why this may be happening?  If this is an NTP issue where in CUOM or CUSM do you check the NTP server?

Thank you.


Hi Connie,

This seems to be a NTP issue. Did you get a chance to check under the control Panel > Date and Time > Internet Time tab.

Hi Pari,

how to change the Time zone on application CUOM & CUSM  from AST to this format GMT+03:00 (Kuwait,Riyadh)

As we are installed Cisco IPT monitoring applications i.e . CUOM & CUSM .On MS-Windows Server 2003 .

from command line we configured the ntp server list, as ntp server is available in network .

On server time zone is displaying correct time GMT+03:00 (Kuwait,Riyadh) But on these application CUOM & CUSM Getting the wrong time zone

Example :

First Discovered Mon 07-Feb-2011 14:23:29 AST ( It Should not be AST )
Last Discovered Sun 20-Feb-2011 02:02:53 AST  ( It Should not be AST)  (it should be like this GMT+03:00)
List Report  as of Sun Feb 20 09:16:58 AST 2011

Actual time zone must be  GMT+03:00 (Kuwait,Riyadh)

On server date and time properties > Internet Time Tab >

So please advice how to change the Time zone on these application CUOM & CUSM  from AST to this format GMT+03:00 (Kuwait,Riyadh)

Thanks & regards

Syed .

Waiting for your response !!!!!!!!!!!!!

Hi Syed,

Usually system time change on the OM Servers are not recommended after it is installed. The system time should be taken by default. If that doesnt seem to be happening, you might want to try restarting the services.

The only other option left is to set the system time and then to re-install the application.

Hi Pari,

Thanks for your feedback, I would like to discuess  on CUSM ,Cisco Sensor 1040 report  , MOS = Unavailable .

We have been installed 5 cisco sensor 1040 on different location ie. Head office and branch office.

From Csico unified Service Monitor > Sensor Report : MOS value dispaly : Unavailable once i click on this link its getting an error:


You don't have permission to access /qovr/ on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

we couldn't find complete report on cisco sensor 1040  .According to the sensor report

Name , Id of sensor OK , But Speaker DN , Device Type not available its blank & on listener side DN, Device Type available ex; 1234 , 7911

And its also be vice Versa , its getting the information on speaker side but at listener side its blank no information ,

Primary Degradation Cause
N/A , Packet loss                         And Code :G711Ulaw 64k, G722 64k

So please advice find the MOS Value on Sensor report .

Thanks & regards


Hi Syed,

If this is https and if it works on http, then you might be running into CSCth45675.

For the DN name being blank, can you find out if those calls are to a Voice mail ?
