Sample Installation of Asterisk PBX?

If you're like most people, you can read an entire installation manual four times over but it still does not compare to studying an actual installation and tweaking it to fit your specific needs. This section will help you in not having to re-invent the wheel and being able to capitalize on the time that someone else has already invested during their installation.


Asterisk can be used for literally hundreds of different communications scenarios or requirements and this is one of the major reasons Asterisk has gained so much in popularity. The Asterisk PBX installation referenced in this document pertains to the following scenario (hopefully it is similar to yours):

  • Small Office Phone System
  • Replacing a proprietary Lucent Partner phone system
  • 20 People
  • 8 POTs (Plain Old Telephone) Lines
  • Voicemail box for each person
  • Individual Extensions for each person
  • One IP Phone installed for each person
  • CallerID Support

The following is a list of hardware selected for this installation. Keep in mind that Asterisk will run on any Linux based system and the hardware you choose may be different from the hardware used for this specific installation.
