Actually this sounds like a really nice idea. It would be cool to have a way to 
start using less intensive bandwith codecs for new calls when bandwith reaches 
a certain threshold.

For example:

- 0-40% bandwith: g711
- 40-60% bandwith: g729
- 60%-80% bandwith: g723
- 80%-100% bandwith: drop new calls, or maybe use lpc10

It wouldn't help in SOHO usage but when using Asterisk as a call termination 
gateway, it would help making the most out of available bandwith. g711 is 
certainly better than g729 when you have the bandwith, and i'm pretty sure that 
even lpc10 sounds better when on non-saturated bandwith compared with g729 with 
some packet loss...

How would you go about implementing this?

Cheers,
Jean-Michel.
