` Welcome to IP baby, you really can't lock it down using the traditional methods.  As much as you would like to think that the entity converting the IP to PSTN should/would/could/does correctly specify the absolute correct ANI/CID it is quite the opposite on a large scale.  Unless someone dreams up a new way to enforce or efficiently verify CID/ANI and the big boys actually implement it   this isn't likely to change.         

Digital signatures?  a la RSA?     

 come on at least try to think it through.

OK, then, never mind.

  How are you going to pass   the signatures for calls not originating via IP? call setup times just   get slower, and packets get bigger.    

Your alternative?
