Small Office Telephone Systems

Hello, my boss asked me to find a way to drastically reduce our telephone costs. Although I do not handle phone systems for example, I am a computer IT Guy and figure I can handle this.
We currently have 30-year-old former telephone system dinosaurs supported by Avaya and routing of four telephone lines with ATT .. then a dedicated fax line fifth, which goes to a computer with fax software. Total 5 phones is a small office.
My goal is to reduce telephone lines 2 or 3 that the business is very slow (we do announce a number too). I hope to get rid of any telephone system (which resembles a large painting and is taking a large closet) and get rid of Bill Avaya too .. phones can be purchased on eBay for cheap when they break .. . we only pay for Avaya to keep the living dinosaur, and they do not want to do. Basically, the features we need in the office are the ability to put calls on hold and the boss loves his speed dial ... intercom would be good.
Any suggestions .. What would you do? Links to routers or VoIP phone, or something would help. Thank you.

Here is a link to a good VoIP equipment that might be able to do the trick:

There are systems office phone provider who can update your phone system. See www.virtualpbxcompare.com for a list of suppliers decent. Flag

Here is what I propose:

Setup a machine used to run the "Asterisk open-source PBX phone system. It should not be as powerful a PC 1 Ghz with 256 MB of RAM should be quite sufficient for managing a small business. Asterisk is a fully featured telephone Private Branch Exchange that provides a solid platform to build and manage enterprise telephony.

Asterisk Cost: $ 0
Cost PCs: $ 0 (assuming you have an old PC lying around somewhere, you can use, you can also use the PC Fax for Asterisk that is integrated in the processing of fax)

You'll need a telephone interface card to connect the Asterisk AT & T phone lines.
Digium (Asterisk Company ") has its own brand of cards, but they are a bit expensive.
This phone card lets you connect up to four telephone lines to the Asterisk box for $ 645.

Now there is an alternative to Digium cards. Personally, I use a card Openvox and it worked very well for me. They are almost exact replicas of the Digium cards made by a Chinese company and they are only a fraction of the cost.
A card costs $ 170 for Openvox 4 lines. Note: Make sure you order it with 4 FXO ports, and not 4 FXS ports (FXS is for internal phone extensions ... I'll talk about that later).

Total cost to date is $ 170. This allows you a management system fully functional and customizable phone that can handle up to four external phone lines. So far it only works with soft-phone extensions, well (ie call via your computer and headphones), I will discuss the following telephone extensions.

Asterisk can interface with internal phone extensions in different ways. The first way is to use this phone card above, but instead of port FXS FXO ports. This will allow you to connect any standard desktop / cordless phone as an extension on the Asterisk server, and $ 170 gives you four extensions, (and you can link up trap.
