[K12OSN] IP based PA system?

[Brandon Kovach]

I have messed with (and will implement ... sometime soon) and Ip phone
system.  We will probably start off as a purely Ip PA system.  I tested
and liked, Asterisk @ home.  Look it up.  I think it will do what you
want.  you have a server and either real or soft phones.  The server needs
to be a bit of a bang-up multi-processor type, but we had 5 phones working
on a PIII server, so that might give you some idea as to hardware.  It was
terrifically easy to set up and documentation is great.
