[VoIP] Asterisk-SIP Trunk

John,
My early *boxes had a single X100P card in each, the current and
previous two *boxes each had two X100P cards in them. At the best of
times I have found them to be 'iffy' but once started and running
usually very reliable. So far every *box has had a different motherboard
each with its own interrupt problems. My first two *boxes were built
with AMD XP1800 and XP3000 CPUs, the third with a P3 450, the fourth and
fifth with P2 350 CPUs and the current *box with F7 and Asterisk 1.4.13
is running on a P3 600 CPU. The first two were originally homebuilt PCs
running Windows Millennium and Windows XP, the third was an original PC
which I purchased new in 2000, the next two were two of ten PCs donated
to me by a school where a pal is the IT manager and the current *box was
a low budget defunct machine given to me by a friend and neighbour a few
months ago, all I had to add was a new hard drive and it seems to be a
very reliable *box although I have refrained from upgrading Linux as
that is in my opinion an unnecessary pain especially now that I have
just a single serviceable *box.
Of course at my disposal apart from the X100P cards I do have some
Pluscom ATAs each with one FXO and one FXS port that I have yet to try
but the downside to any of these external devices is the fact that they
each require a separate PSU. Currently I am using a couple of Tiger ATAs
and I was using a Sipura SPA2000 dual FXS on my experimental system. The
Sipura I found really over engineered for CNET requirements and it had
the annoying habit of intermittently ringing whatever was connected to
it day and night even though no incoming calls were present. I solved
that by unchecking just about every option on both ports. I think the
ideal interface would be something like an external 8 or 12 port dual
FXO and FXS box. I have seen such things advertised on Ebay but they
seem to be rather pricey.
I am looking at perhaps putting two *boxes in one *box, I have a couple
of old tower cases that might be suitable and half a dozen P2 350
systems to source the parts from.
