[PLUG] Checking out a VoIP attempt...

My brother is working on a voice over IP attempt of his own using Java.

On a 11 mbps wifi network running into a 100 mb/s network we could talk
just fine.

Naturally the thought was to try and run it through our DSL.  He
expected blank spots maybe, there's a lot of static though.  I
guess there's a way to compress a 16 bit 44 kHz audio stream.  
Another option is to record a minute and require it to be 
buffered at the remote end before it plays back, but he wants 
to get as close to live conversation as possible.  It seems 
like a great piece of software, as is, for use over a lan
though.  It works over 10 mbps and faster connections.

What are the common ways of addressing random latency and
the sub lan speeds of broadband connections for voip 
deployment?  I hear rumors that cell phones modulate the
noise etc. and actually calculate on the fly how to tell
a remote cell phone how to reproduce your voice.  Apparently
on a cell phone, it's not your voice but a computer 
reproduction that's heard.
