Robocallers Win Even if You Don't Answer (wsj.com)
Sarah Krouse, reporting for WSJ: Caller ID is feeding one of the very problems it was developed to stop: junk calls. Illegitimate robocallers, or outfits that flood American landlines with marketing calls, use the decades-old identification system to make money, even when no one picks up. While scammers' biggest paydays come from tricking victims into handing over credit card or bank account information, many robocallers make incremental cash along the way, thanks to little-known databases that try to identify who is calling.
Each time a caller's name is displayed, phone companies pay small fees -- typically fractions of pennies -- to databases that store such records. Some of these fees are handed back to the caller. With millions of automated calls a day, the amounts can add up. "It's slow nickels, not fast dimes" for scammers, but it helps offset the costs of making the calls, said Aaron Woolfson, president of TelSwitch, a company that licenses out telecommunications-billing software.

At least do me the courtesy of reading the whole damned post. It wasn't that long. It wasn't even as long as yours. In particular, read the second damned paragraph again and again until you see that I answered your concern before you even raised it AND proposed the solution you suggested.
As for voip, it's on them to either provide proper caller ID or pay the fines themselves (see 1st paragraph) or if they are not in FTC jurisdiction, see 3rd paragraph.
