If this is for commercial use, especially if you are going to be selling this solution, I would suggest that you don't even offer the choice of analog lines except in the smallest of offices. Unless you like to spend a lot of unbillable time supporting them :) Most businesses of more than 8 to 10 people should be able to afford T1 service. Depending on your area, business analog lines can cost more than $70 a month per line. This can quickly add up. A channelized T1 with local phone service runs about $400-$500 in my area, with the added benefit of getting DIDs and less of a headache. I agree with the person who responded below: low budget minimum configuration will screw you and your customer. They are probably going to take out a line of credit to pay for your labor (billable and included in the total price that you quote; you do have a contract, don't you?) and the cost of hardware. You might as well quote them good hardware that is reliable and dependable, and will suit their needs for a few years to come. Buy commercial with a support contract, or be prepared to keep spares of everything. It seems to me that a lot of people using Open Source software (I disdain the term Free, because nothing is) are in the "Cheap Cheap Cheap!" mindset. This is great if you are doing it for yourself, but it's not a good idea at all if youare trying to sell the solution to customers. Now that I have that off my chest, here's what I reccomend for a business package: Server: Dell 600SC with 2.4 Ghz proc, 512 MB RAM, 2x Hard Drives in RAID 1, 3 years 24x7 4 hour response on-site support for hardware - $1550 Two T100P T1 Cards: One for the local T1, one for a channel bank. - $990 or you can get a quad span T400P for $1495 From the archives it seems like the zhone channel banks are kind of crappy, so I would go with a Adtran Total Access 750 which will run you about $2500 The phones - Don't forget the phones! - Pick one you like and stick to it. Don't go to WalMart of CostCo and buy phones. I like the Aastra PowerTouch 390, which I think are about $99 each. It sounds like a lot, but I've had good luck with these phones. So the total hardware will be somewhere around $5000 for a phone system that can handle up to 24 users. When you compare it to other commercial products that go for about $1000-$1500 per user, that's a considerable savings, plus you get a better product. Don't forget to add in your cost for building the system Reocurring charges will be: $400-$500 per month for local phone service, maybe more or less depending on who the LEC is and if they have a package allows you buy less than a T1 of service (just a few channels). Long Distance - who knows? I've seen businesses pay as little as 1.7 cents and as much as 12. Shop around for your customer and make a good recomendation. Maintainence which should be a percentage of the total sale, billed annually, unless you (or they) want to charge for support on an hourly basis. And don't forget to contribute a bit to keep the project going ;) -Tim

It's not for my personal use: I'm trying to tailor some
commercial offer for
differents kind of customers. So I need to find the competitive
advantage (if
there is one... but I'm pretty sure of this...) not only in
terms of
functionalities and versatility, but also in terms of costs, in
respect to
traditional PBX solutions.

Thank you! Your answer was very useful for me!
