Reducing a system is one thing, shooting for absolute minimum leaves little to no expansion ability. Also from the stand point of the original question, it is setting up asterisk to essentially fail through no fault of the software. Once the person who was asking the question has gained enough knowledge to diagnose problems, then the same person is knowledgeable enough to know when the problem stems from reducing the computing power too much. > For a big installation everything lives in the server room but > in a home or very small office it's on the desk or under it > where every cubic inch and decibel matters.

While I enjoyed my visit to California a few years ago, this helps remind me why I was glad someone else paid my way. Maybe you should consider relocating where your cubic inches aren't so expensive and the power is less expensive. Power here in the TVA valley is fairly cheap. I currently pay only 6.545 cents per kwh. This is after our recent rate increase. It use to be 6.178 for the first 2k kwh and 6.817 over 2k kwh. I realized from your post that I could not afford to do a lot of the things I do if I had to pay your rate for electricity and the increased cost for gas. No wonder so many people that way want to come off the grid and make their own power. > In enginerring, "how small, how light how cheap, can I make > this thin?" are good questions to ask Yes, but an engineer would be dissecting the problem and answering the question for ones self based on a well founded definition of the problem. So you realize that a question worded exactly the same can have different meanings depending on where it is coming from and the reason to ask it. BTW, tying in your power consumption comment, I have seen it mentioned that the average linux config is responsible for computers using more power than needed. Many of us, myself included, do not turn on power management in our kernels. This is due to the support for power management in older hardware not working very well. Now that it is better standardized and been tested much more, the newer hardware should be able to handle being throttled back. So for an engineering question, are we getting more work done per watt of electricity in newer machines? If so, can we combine this with proper power management to produce an even more attractive result? You can see how this is more interesting and better directed than a question that basically leads us down the "will a P200MMX machine be enough to handle my T1 and 30 employees?" This is exaggerated, but you can see the difference here. Of course even the exaggerated example above is better than the original question here that didn't specify intent or goals, just a nebulous "what is the bare minimum". -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
