You clearly haven't made any PSTN calls on Skype. If you're looking for higher sample rates, it's relatively easy to use a B channel to transport g.722, or even bond a couple together for 128k AAC/MP3/any other codec you'd like. Not only do you not have to deal with the problems of internet routing, you aren't stuck with underwater sounding CELP codecs. Anyway, if you're arguing voip should replace the PSTN, I'd hope you'd at least have something hinting it could be as reliable.

> You clearly haven't made any PSTN calls on Skype. I did, and the reason some calls sound horrible, is because Skype is trying to save up some money hiring shitty carriers/providers. > it's relatively easy to use a B channel to transport g.722 Why would you use an HD codec to transcode to G711? Call on any direction can sound only as good as G711. > Anyway, if you're arguing voip should replace the PSTN, I'd hope you'd at least have something hinting it could be as reliable. I agree with most of your arguments. VoIP isn't ready now, but it will be soon. Just remember how the Internet was 10 years ago, and how it is today.

  > Why would you use an HD codec to transcode to G711? Call on any direction can sound only as good as G711. The idea is to use the timeslot g.711 normally would sit in to transport your own codec. Studios use this technique pretty frequently when they hire voiceover talent or do remotes.
