You are confusing what is presented to the end-user with what might be going on within the infrastructure service.
Call progress tones are the former and their primary goal is to keep the user happy, providing very constrained information. Especially for mobile phones, there is often all sorts of forwarding signallying going on while you hear to tones.
I understand that--and had not considered that the global inventory of MTAs could be swapped out with stuff that could handle the redirection mechanically. I had left the telephone business by the time SS7 came along--how was that introduced? (I have assumed that it was as the #2, #4, and #5 machines and their equivalents were swapped out for ESS machines for a lot of additional reasons.)
In general, a core problem with the Knesset law is that it presumes something that is viable for the phone infrastructure is equally - or at least tolerably - viable in the email infrastructure. Unfortunately, the details of the two are massively different in terms of architecture, service model, cost structures and operational skills.
No kidding--something like making airlines do something railroads can do. -- "Government big enough to supply everything you need is big enough to take everything you have."
