Adam,
DO NOT CALL THE CUSTOMERS.
Are you looking at an EFO.? (will understand if you don't answer either way).
For the people who are wondering what an EFO is. It is an internal VM 'Extended Format Output' datafield that details Switch Code, Start Date of call, Start Time of Call, End Date of Call, End Time, Duration (
in seconds !!), Originating Number, Terminating Number, Answer Detect (Y/N), Valid Staus, Valid Code, Billing Number, Divert Detect, Sequence Number, Input Filename and CDR Type.
If you are privy to this information (and not many outside VM are) then it should in theory be an open and shut 'no argument' case.
Certainly in our case (and possibly many many others) this is not the case at all.
VM just don't pay - stating 'AIT'.
Yes Adam, it would appear we are lookning at wholesale fraud here on the part of VM.
