Skype is certainly better than the PSTN when going Skype to Skype, but 
why do people think it sounds better than the PSTN when going to the 
PSTN? Is it just psycological, or are they using an environment (e.g. 
headset) that just sounds better than their usual phone? Having they 
been using a Cisco 7940 with G.729, where a real PSTN to PSTN connection 
would sounds rather better? I find it an interesting comment that Matt made.
