I think that is significant, even if the routing is still going through the 
Banana.

Multi-core CPUs are only a benefit if you can run separate applications (or at 
least separate threads of an application) on the separate cores.

I'm not sure Asterisk can do this for a single call.

Can you get the full 50Mbps through the Banana when you're doing a download of 
something biggish?

The big difference there, though, is that Asterisk (running on the Banana) is 
not handling the call, so you have the traffic being routed through the Banana, 
but Asterisk is not being asked to do anything with it in the middle.
