The government wishes they could do something about number spoofing. There is a task force working on it, but it probably will only work on SIP networks, not the SS7-based PSTN, mainly because there's so little investment being made in maintaining that.
But the design of the PSTN is not terribly secure. Caller ID is asserted by the originating device or carrier. An originating carrier could screen it to be sure that the number is one that the caller owns, but they never do, and you have to bear in mind that incoming and outgoing calls may go through different carriers, so the outgoing carrier has no way of knowing your incoming numbers.
Even if the originating carrier verified the number, calls are sometimes passed through multiple carriers between origination and destination. More room for shenanigans... you can't really tell who the originating carrier is, especially if it arrives VoIP.
The calling party name is a totally different beast. This is NOT passed across the PSTN. In the FCC's infinite wisdom a couple of decades ago, they let the network pass the number while the terminating carrier, who sells Caller ID with Name as a premium service to its own customer, looks up the name in a table. They can of course query the originating carrier's Line Information Database to get the canonical result, but carriers charge huge fees for that. So instead you have all sorts of weird caches of names lying around, some years old, and your carrier may thus be using old, or wrong, information.
It's all very freedom-y.

How long did it last? Did you have to change your phone number?This is the second day in a row. We changed our voice mail letting people know and asking them to call the FCC - we called the FCC yesterday and reported it, but they need the people receiving the calls to call and complain.any thoughts appreciated.
