You might want to consider breaking this up a bit, just for ease of reliability and maintenance. If everything's all on one box, then it's impossible to do maintenance without taking out *everything*. If you divide it up a bit, then you can take down half of your external lines at a time, probably without losing any real functionality.
- Can I get my NMS AG-T1/E1 card working with Asterisk for tinkering purposes?
Probably not.
- What kind of uptime am I going to expect on Asterisk? Am I going to have to
reboot the server every 2 weeks? Can I hope for carrier class service?
In my experience, you should see similar reliability to other Linux-based network services once you get things up and running. Which is to say, I'd expect uptimes of 1-10 months, depending on usage levels and security upgrades. That's not carrier-class, though.
- Is it possible to change extensions on the fly? For example, this week 555-
1111 rings in unit #10. Next week theres a different tenant, so i want to make
555-2222 ring in unit #10, and send 555-1111 to voicemail. Some kind of GUI to
accomplish this would also be nice.
That's pretty easy. The user interface for it will be tricker, but the back-end logic is really simple.
One other thing to consider--the useful lifespan of an Asterisk system is probably somewhere around 5 years. After that, you'll probably want to replace it with something newer, even if it's just Asterisk running on newer, faster PCs. During those 5 years, you'll probably need to replace a hard drive or two, and maybe one or two other components, like power supplies. You'll probably also want to install security upgrades from time to time. Asterisk is a powerful system, but it requires some amount of ongoing maintenance, and that's something that you'll probably want to factor into your plans. You can't just install it and then leave it alone for years at a time, unlike some cheap phone systems. The payback for that is that it's vastly more capable and generally a lot cheaper then competing solutions.
