I have a phone number of a customer that insists they called in from say Jan to March - I can see 2 instances using UCCX reporting but they insist they called a 3rd time. Just to ensure they didn't get to talk to someone by "zeroing out" how can I trace their calls through the system BEFORE they would have hit UCCX? Does Unity or CM not have some means of tracking a phone number? The only options I see in CDR are for internal extensions.
