I don't think that's correct.

I don't have the link to the Columbia paper where they tried (with only 
mixed success) to figure out what all nefarious stuff Skype does 
(hijacking port 80 being the most pernicious) but I'm pretty sure they 
have figured out that if possible, it will use the (proprietary) 
wideband version of iLBC.
