Question: does this actually reduce packet-drop exposure? One would 
think that with a longer duration of audio captured in a given packet, 
the loss of any individual packet would have more negative impact upon 
voice quality as subjectively experienced.

Or does this thesis lean on countervailing tendencies, such as overall 
reduced PPS in a higher ptime scenario?
