Most of them these days appear to be accomplished by corrupting the call data going to the 911 center and then the caller tells the operator whatever fake address they want.
Spoofing caller id does not often work because 911 centers use a more powerful system for identifying calls that is like ANI.
There was a presentation at DEFCON this year on this very subject.
- viraptor 12y agoHaven't seen the talk, but that wasn't my experience after working for a VoIP provider. Being your own operator you publish whatever number you want and customers are in charge of putting their correct address for use by the emergency services. For services where you intend to keep all the right information, this call can be still tracked later on. But there are providers who don't care. Basically at each hop they would have to rely on that hop playing nicely or you can't get more info.
