I am only talking of SMS and phone calls. The standards are old, it was 
considered impossible to access the cables carrying the trunks. 
Technology was naive.

At some point probably they thought that the transmission department 
would do the encryption when possible and advisable. The switching 
department needed the trunks in the clear. The available machines could 
not do encryption.

I don't know if the new methods using VoIP use encryption.
