Digital Journal has (as of the same day I'm writing this), published a report about these annoying phone calls from obscure numbers. Over the last few days, I have been reading the postings here at WhoCalledUs. The story is the same: The Phone Company bundles numbers, which are then sold. These numbers are bundled into groups of 1,000 numbers. If a complaint is filed against one number, the people who own it can simply roll over to the next number in the bundle. For example, 856-201-0001 will change to 856-201-0002.
You and I pay a lot for our home, cell, and office phones. Many of us have joined DoNotCall, and wonder why it is not blocking these harassing calls. If it could be made unprofitable for the Phone Company to bundle numbers and sell them, that might put the brakes on this kind of annoyance. Unfortunately, they will find another way to get around any firewalls. They are making too much money.
