I have a situation where I am doubting the data I am given from MAT. It is not clear what is causing this issue. We have non-ACD phone that do not have Charge Keys showing in MAT as having charged random calls to random valid account codes. If the phone does not have a key then, how could the phone charge a call? Where would this corruption be coming from? Would it be something in MAT? Would it be something coming from the PBX? I have found this in 81Cs, 61Cs,and in 11Cs. These switches all use a MDR buffer to a central MAT console. All switches are on release 25.3. So far, this is only happening to DID numbers.

EX: Non-ACD, DID extension 1234 places a call to California. In MAT this call will show the call being placed and that it was charged to account code 2468. The next call will charge to account code 9876. The next 20 calls could go through just fine.

Account codes are set up in the Customer Directory of MAT. This is the only place that these are listed. We know that the database will accept any number for an account code reguardless of what is in the directory.

Any MAT/Switch guru out there feeling generous? This is rather urgent. It could be a legal issue if we are not extremely careful. You guys may want to read this a few times. I will thank you in advance for walking me through this.
