I'm afraid you're going to find this with pretty much *every* phone.  Normal 
POTS phones just don't have this problem because the delay is low.  I would 
imagine that Polycom would have the least problem with this since they are 
known for their superior audio, but as I do not own any and have not used 
any, I cannot say for certainty.

Honestly you said it yourself though... they are turning it up too high and 
pushing the audio beyond what its design specifications are.  This is perhaps 
the fault of the software guys, as they allow you to go beyond what what the 
acoustic coupling was good for, but then again I am pretty sure they allowed 
the volume to be increased due to customer complaints of the phones being too 
quiet.  :-)

Well when you buy on price alone...
