If you are a small business and you are technical or have an employee that is then Trixbox for Asterisk is for you. PBX systems can cost tens of thousands of dollars. If you setup and configure your own Trixbox PBX you get all the features of these commercial systems and more. All of this can be done for around $500-$1000. If you don’t believe this or think it is too good to be true I run my commercial business phone system on Asterisk. You can call and hear a demo at 602 445 9816.
