Basic IP PBX Phone System Setup Information

The IP PBX (Internet Protocol Private Branch eXchange) is a type of phone system designed to utilize the internet in transmitting voice, video and other data. IP PBX can also be used in exchanging information with a PSTN (Public Switched Telephone Network). It can also be merged with the VoIP (Voice over Internet Protocol) to avail of cheaper call costs. This IP PBX phone system is available as software, hardware or a virtual variant.

The main components
  • PBX software – open-source software from the likes of Asterisk, FreeSWITCH, OpenPBX, etc, can be installed and configured on a decent PC with a minimum specifications of 450MHz CPU, 128MB RAM, Ethernet and built-in sound.
  • Phones – SIP phones from Avaya, Cisco, etc. can be purchased and used for this phone system. But sometimes it is easier to get started with the soft phone, such as XLite, that is installed on a PC. Older analog phones, with the use of special adapters, can be utilized as well.
  • SIP gateway – allows the phone system to communicate with other PSTN phone networks. In order to obtain this,  a paid service subscription from providers such as OnSIP, MediaRing, VoiceJet, etc. is required.
  • Network – a basic home networking behind a NAT firewall or gateway router is all that is needed. It is important to have a static IP address assigned to the IP PBX system.
Setting up the system
  1. Sign-up with a SIP service provider. It is recommended to find a suitable provider that offers an affordable service. Subscribe by visiting and registering in the provider’s website.
  2. Set-up the network by picking a static IP address.
  3. Configure the phones to be used.
  4. Install and configure the PBX software.
