Unallocated numbers and CDR

[CUCM55120]

Hi,

I am wondering how to solve the issue of endless call records to unallocated numbers in reports from CUCM. Whenever I export the CDR files or check on RTMT there are loads of instances where an unallocated number has been dialled and there will be hundreds of call records within a second for that call all with the error unallocated number.

It is rather annoying to go through all the results with half of them being erroneous and when importing the CDR data into a program to create graphs etc the hundreds of unallocated number records mess up the stats to make it look like tens of thousands of calls are being made within a couple of hours.

Is something configured wrong and causing these calls to get stuck and retry endlessly rather than terminate?

Thanks.

Hi,

System Parameters

–CDR Enabled Flag—This parameter determines whether CDRs are generated. Valid values specify True (CDRs are generated) or False (CDRs are not generated). For this required field, the default value specifies False. Enable this parameter on all servers.

–CDR Log Calls With Zero Duration Flag—This parameter enables or disables the logging of CDRs for calls which were never connected or which lasted less than 1 second. Cisco Unified Communications Manager logs unsuccessful calls (calls that result in reorder, such as might occur because of a forwarding directive failure or calls that attempt to go through a busy trunk) regardless of this flag setting. This represents a required field. The default value specifies False.

Set this CDR Log Calls With Zero Duration Flag to False.
