Welcome to our new website CallCatalog.com which is a reverse phone directory. How many times have you received an unwanted phone call that you really don’t want. They come in many shapes and sizes but their either a wrong phone number — which seems to happen less and less since people store phone numbers in their cell phones now, and telemarketers or other truly undesirable callers. SO, what can you do about this? Well first off, the best thing to do is to report them on the do not call list and also post the phone numbers on the internet to share with people.
