The article states that Verizon is watching this.
This is such baloney. Neither the LECs nor the FCC have ever been the least bit concerned about CID spoofing.
The FAA had a great idea to force ubiquitous CID in 1995, but they reserved a decision on private exchanges, etc, thus opened the door for spoofing.
The FCC never resloved that one.
Oh, wow, now the LECs are working on it ahead of Congress.
Yeah, right.
