Please read this skype experience:

"The sound quality is amazing, like the person you're speaking with is 
sitting right next to you. You can hear so much more than you can get 
through a phone." 

It's clear that a wide bandwidth is giving a better audio, a better 
experience. 

Skype may be using a 24 KHz bandwidth. I know that they're also using
a very good compression codec.

Of course Skype may also get a crappy sound because of Internet 
congestions, but that's another problem.

A high audio bandwidth with a simple adpcm codec would be a great 
improvement for asterisk (at least over a private lan). For an 
Internet call, you'll also need a very good codec.
