That's easy: when it starts echoing.  ;-)  (Or, rather, when it starts 
echoing in conditions that the specs say echo shouldn't occur under -- 
eg., taking into account length of the tail, etc.)

However, while I may have been wrong (I now know that G.168 is a spec, 
not an algorithm -- no doubt something I mis-understood while talking to 
my friend), I can state that the Sangoma card has really, truly made all 
the echo, clipping, and other issues I'd had simply vanish.  I can 
scream into the phone, I can whisper... it's beautiful.  And this is 
calling people where, w/o EC, I had horrible echo.  (For some reason, my 
Verizon cell phone's VM -- not the phone itself -- had INCREDIBLE echo.  
*gone*)

So, put me down as a satisfied customer.  And, no, I'm not taking 
kickbacks.  ;-)
