But it did not produce different output nor accept different input; it
wouldn't have mattered if an Intel-based system was talking to an
AMD-based system, because the data *outside* the system was the same.
That was my point. There are many CPU family-specific optimizations that
can be used for various parts of Asterisk, but in the end they don't
affect how Asterisk operates, only the speed at which it does so.
