[ns] G.711 codec

[Ilyes Gouta]

Hi again,

Just as a follow up on the G.711, the simplistic UDP/CBR model won't
be useful if you want to simulate stuff like silence concealment and
activity detection which are actually two key elements, encoders can
use nowadays to efficiently compress audio.

You can still use the UDP/CBR model but you'll have to say it clear
that it has such and such limitations. You can start with it, do the
work and then if you find a better model you can always change it. It
always involves modifying just one line in your tcl script and
rerunning the simulation.
