Digium, the creator of the open source PBX, has created a market for the build-it-yourself BPX systems. Many organisations consider it because of its unique features, flexibility and enormous cost-savings. However, it is important to note that just like other technical build projects, rolling your own phone system comes with a range of pros and cons.
· Step 1: Buy the server – The Asterisk software that is adequate to support an Asterisk installation can be purchased for less than £600.
· Step 2: Install the server software – Begin by setting up a Linux operating system, which is a very straightforward process.
· Step 3: Install the Open Source PBX software – Your options are leading Asterisk-derived products, namely: AsteriskNow, PBX in a Flash (PiaF) and Elastix.
· Step 4: Connect to the outside world – Your options include adding in appropriate PTSN analog or digital gateway if you want to connect to a public switched telephone network or using SIP Trunking, which has no hardware component.
· Step 5: Choose your telephones – Since Asterisk is based upon the Session Initiated Protocol (SIP) standard, you can use business telephones from many different manufactures. However, provisioning your telephone of choice to work with your Asterisk system can be a bit of a challenge as each phone may require up to an hour to be set up.
