Yes, exactly.  It IS a debug level message.  It was changed to an error 
by mistake.

The conditions that make this message come up are not a sign of problems 
with your Zap stuff.  It can happen when there is jitter on your 
network, and given that you were using a WiFi phone, I'm sure that is 
the case.  Also, note that the "audio may have been lost" part was a 
part of the change to be a warning, not the original debug message.
