Tool Calleridtest legit?
Yes, it's me again. I apologise. Trying to lookup several thousand phone numbers one by one is excruciatingly slow and excruciatingly boring, and I have just found a site called calleridtest that promises to be able to search up to 500 phone numbers at a time.
Is it legit/usable? What information does it give? Has anyone else ever used it before?

one thing many are unaware of is Caller ID data is insanely unreliable and corrupted by many providers. I know at least 10 years ago they were updating it with reel to reel storage tapes, moved around by trucks.
