One of the cases where an incomplete CallerID may cause problems with queue stats due to a CID number not being shown, is when your incoming CallerID has only a number.

For example, if your incoming call has only a number as a CID and its 07123456789 ^*, your DID has the 'Replace CallerID' field set to 'Support-%CALLERID%' .  When this happens, queue stats will show the call without any CallerID which is a problem when trying to analyze given stats.

To fix this problem, set the 'Replace CallerID' field to this: 'Support-<%CALLERID%>' which should show CID (at least the number part) in the queue stats.
