Scott, my recollection was that SS7 only affected the call setup but not the transmission characteristics. It has been a while ago but that is what I remember.
I believe that the REAL problem was that the system slowly evolved from a battery and ground to a pretty complicated analog/digital transmission system. Those that started with the old common battery telephones JUST KNEW that you had to talk louder on a long distance call.
