I would expect that it depends on the size of your pipe.  I can tell you 
that if I place my voip device on one of my inside switches, and then 
download something, calls get garbled.  Then again, this is DSL, I 
suspect you're using something faster there.

Yes, or place the voip just behind the firewall if that's possible. 
Most of these devices will do qos, giving priority to the voip.
