[Asterisk-Users] Dinosaur *

[Edwin A. Silva]

I had a T100P running on a celeron 333/w 64megs RAM running RH7.0 and
asterisk with 4 extensions music on hold and a couple other things
running on it.  I never had any problems.

Hmm.  Maybe the dinosaur would make a nice answering machine.

I've got a 266 Celeron in a laptop running W-me.  Not much of
powerhouse, 
that one.  It was better when running Linux.  I like the AMD 
price-performance points personally.

OK.  That makes me recall some things I read in the archives about DSPs
on 
boards vs not on boards.

line side? generates ringing?
http://www.marko.net/asterisk/archives/0001/0098.html

Instead of routers I was thinking of using a twist cable with RJ45 on
each 
end:
1 RT - TT 4
2 RR - TR 5
4 TT - RT 1
5 TR - RR 2

The PRI link is only one meter in a captive environment.

Based on everything written so far, I think I'll build a couple of
low-end 
machines sooner rather than later.
