You can overcome most of those problems by buying good quality hardware. If you buy your * server from your local Taiwanese clone shop, you're asking for trouble.

No Solaris support, but you might be able to get away with Linux/Solaris...but then you lose a lot of the hot-swapability. In my experience, though, the only things I've ever been able to hotswap were power supplies and hard drives...and thats not software/os dependant. > One of these days, I may convince myself to buy a modern Sun box (maybe > the ~$1000 Blade 100s) and see what can be done.

Its when programmers who believe that the world revolves around Linux/i386 that you have problems. Personally, I'd stick my Digium cards into an Alpha of some sort. A DS-10L for 1U mounting with 1 card or a DS-20 for multiple cards where you need lots of processor zoobs. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
