[AG-TECH] AG2.0 RAT issues

James,

I ran into this problem and the only explanation I have is RAT's solution 
to the echo problem is to turn off duplexing.  So you can only send or 
receive at a given time.  So what happens?  Someone who, like most of us, 
doesn't have the echo cancellation box checked, turns on their talk and it 
shuts yours off.  You may notice that when this happens your node in RAT is 
no longer highlighted and when all other nodes turn off their talk, you can 
once again send audio.

The only solution I have found is to get an outboard echo 
canceller(Gentner, Polycom) or use a headset.

Hope this helps.
