[Asterisk-Users] Fun with Echo

[Brian Swan]

Actually, that's what I started out with, and outboud calls were the  
same as now, inbound calls had a huge amount of echo (until I turned  
on Aggressive).  In my testing I actually didn't notice any  
difference between KB1 actually worked better then MG2....  thanks  
for the advice, though!
