   That's ancient technology...   
      
   My "phone line" is made of glass, it does not conduct electricity. Ie,   
   it is fibre glass, and the phone is actually a VoIP contraption. The   
   router has a client for it, and outputs a local socket that is an   
   emulation of the copper line, do that we do not need to replace our   
   phones and we are unaware of the change.   
      
   So the meaning of CID spoofing changes totally.
