Next time, I'd actually buy a Dell SC420 or something similar. :-P
Honestly, I'm really scared of Dell hardware. Some of the most messed up computers I've worked on have come from Dell. I hear their servers are better than their laptops and desktops, but having only experienced the bad, it's hard to imagine the good.
Hardware RAID is mostly important if you're going to be doing a LOT of high-capacity read/writing, and want to be able to get another controller that speaks the same language in case the controller goes out. Semi-soft raid, the kind that's on the motherboard, isn't good because you lose your data if the mobo controller goes bad. Linux software raid would be just as versatile in this situation, and a lot cheaper. ;) I wouldn't reccomend it for an office with 50 or 60 or more people that's doing a lot of voicemail read/writes, but for your purposes...
The main regret I have about hardware RAID is that the card is sharing an IRQ with one of the Digium cards. This whole IRQ thing is driving me crazy ... I disabled everything I could in BIOS and that freed up some IRQs, but there's no way to assign a particular IRQ to a particular device. I haven't had to think about IRQs in a long time, and it's very frustrating. I'd still like to hear about hardware suggestions that could avoid this or make this better in the future. Like, are there motherboards that let you assign IRQ to devices?
I'm having some volume fluctuation problems with the SPA-841 phones, which I have as well. The next phone I'm ordering will be something that's a lot more expensive, so I'll let you know if that fixes it... but I'd put a nice network card in your *server before I'd replace all of your phones.
I'd love to hear how the higher end phone does. If anyone else has experiences comparing phones, I'd love to hear them.
Since I get echo and popping noises even when I'm dialing from one extension to another (no Digium card involved), I'm guessing that the problem is at least partly the telephones. Of course, the sound quality is better in other ways (e.g. both sides of the line are clearer), so maybe there are some problems with the Digium cards, too.
