Calls without CallReference and ANI/CLI

[ali.parvez]

I have noticed a number of calls in the Terminatio_Call_Detail without a CallReference and ANI. Could somebody explain me as to why this is happening? Also, can these entries be considered as short calls and in reports can these be related to calls not answered.

If this is IPCC or ICM Enterprise, what is the PeripheralCallType and CallDisposition of these calls?
