If you’re tired of paying exorbitant phone bills for your home or small business, then it’s time to consider setting up an IP telephone PBX on your computer. An IP telephone PBX, also known as a private branch exchange, is a phone system that utilizes the internet to make and receive calls. In this article, we will guide you on how to turn your ineffective house PC into a powerful IP telephone PBX.
Understanding IP Telephone PBX
Before we get into the details of setting up an IP telephone PBX on your computer, it’s important to understand what it is and how it works. An IP telephone PBX is a phone system that uses the internet to make and receive calls, rather than traditional phone lines. It operates as a private network and allows for seamless communication between various extensions within the network.
Choosing the Right Software
To set up an IP telephone PBX on your computer, you need to choose the right software. There are several options available in the market, but we recommend using Asterisk. Asterisk is a free and open-source software that has been around for over two decades. It is reliable, secure, and can handle a large number of calls simultaneously.
Installing Asterisk
Once you have chosen Asterisk as your software, the next step is to install it on your computer. The installation process is straightforward, and there are several tutorials available online that can guide you through the process. Once you have installed Asterisk, you will need to configure it.
Configuring Asterisk
1. Determine the number of extensions you need and decide on their numbering scheme.
2. Configure the extensions in the sip.conf file, specifying a username and password for each extension.
3. Configure the trunk in the sip.conf file, specifying the connection to your SIP provider or PSTN line.
4. Configure the dial plan in the extensions.conf file, specifying how incoming and outgoing calls should be routed.
5. Set up inbound and outbound routes for your system, specifying which extensions or trunks should handle calls to specific numbers.
6. Set up voicemail for each extension, specifying the email address where messages should be sent.
7. Set up call recording, if desired, specifying where recordings should be stored and how long they should be kept.
8. Test your system by making and receiving calls, and make any necessary adjustments to the configuration.
This is just a general overview of the configuration process, and there may be additional steps or customization required depending on your specific setup and requirements. It’s important to have a good understanding of Asterisk and VoIP in general before attempting to configure a system, or to seek the help of an experienced professional.
Setting Up SIP Trunks
To make and receive calls outside your network, you will need to set up SIP trunks. SIP trunks are virtual phone lines that connect your PBX to the outside world. You will need to sign up with a SIP trunk provider to get a phone number and a SIP account. Once you have set up your SIP trunks, you can start making and receiving calls outside your network.
Configuring Phones
To use your IP telephone PBX, you will need to configure your phones. You can use any SIP-compatible phone, or you can use a softphone, which is a software-based phone that runs on your computer. You will need to enter the IP address of your PBX, along with the extension number and password. Once you have configured your phones, you can start making and receiving calls within your network.

Adding Features
One of the benefits of using an IP telephone PBX is that you can add features that are not available on traditional phone systems. You can add voicemail, call recording, call queuing, and many other features. Asterisk has several modules that can be used to add these features to your system.
Securing Your System
Security is paramount when it comes to phone systems. You don’t want unauthorized access to your PBX, as it can lead to fraudulent activity. You should secure your system by changing the default passwords, disabling unused ports, and using firewalls.
