[asterisk-users] Asterisk on AMD

[Lyle McKarns]

All,	
	Thanks for confirming what I had already expected. I just wanted to verify my thoughts with a group of more experienced Asterisk users to ensure I didn't hit any hidden 'gotchas' along the way.

Thanks,
Lyle J. McKarns

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.
