I too restart the asterisk process every night as part of the cron process.
Many people here seem to be under the impression that restarting the
application every day is a bad thing.

It is a bad thing when people consider it a magic bullet.
It "cures" slow resource leaks. But faster resource drains will still
be able to crash Asterisk. Strange races will still happen once in a
million.
And people have actually suggested recently in this list a scheduled
reboot as a cure for deadlock issues.
And what happens if at the time of the shutdown there was a |

I was running Trixbox 2.2 up until about 2 months ago, and had persistent
interrupt issues. I upgraded to 2.4, with the updated kernel, and it?s been
complete smooth sailing ever since.

RTC? on kernel 2.6.23? It should not be used in kernel >= 2.6.22 if
CONFIG_HIGH_RES_TIMERS is enabled.
Also note that on kernel 2.6.9 you have HZ=1000 and thus ztdummy works
quite differently. This is not the same issue as interrupts of PCI
devices.
(not to mention that hotplug on CentOS 4 is strange. And earlier
CentOS4 versions had a plain broken USB stack).

I actually work as a software engineer for a big telecom manufacturer to remain unnamed. I use Asterisk at home and I built a system for my aunt's real estate office mainly because she was quoted $83K+ over 5 years for a 12 station Toshiba key system.

What on earth does that system do? open the office, make coffee, sweep
the floors and ???
For such a small system there is no earthly reason for it to be 10
percent of that, even on a 5 year lease.
Unless there are contract reasons she shouldn't even consider a lease
either.
I know that EVERYTHING is big in Texas, but that is nothing more than
highway robbery.
An NEC DSX with CF voicemail and e-mail integration wholesales for well
under 3K, double that and add cabling . . .
Well, you get the idea.

I fully agreed, that's why we built her an Asterisk based system. Splitting
this up they wanted $724 per month for the hardware and maintenance. This
did include a "special" kind of lease where they could upgrade as necessary
even if it required them to change out the system to do the upgrade. I'm not
sure what that is worth but I'm fairly sure it shouldn't cost this much. The
monthly contract for the Integrated PRI was another $675 per month. My aunt
couldn't see how she was going to afford that so she called me for advice. I
originally steered her toward a key system until I realized she would
eventually need 35-40 stations. So we rolled our own asterisk based system.

No, I meant if I leave this office, what to do when the cpu fan or power
supply breaks on our current * box They might just be so worried
that they'd *want* something like the 3Com V3000

Interesting When I (the tech guy) leave this office, they just

You don't run into choppy audio with IAX that way? I see that alot
and the simple solution is to switch to SIP, almost always solves the
problem right away.

Not really, but both ends have zaptel hardware. I'm really surprised
IAX2 connects and functions to these 1.4 and 1.6 beta servers from a Pre

That probably includes 5 years of support but still expensive.
