What is an Open Source PBX?
If you are a VoIP user (or thinking about being one), you must have heard the buzz word: Open Source PBX. But what is it? What does it do? Let’s find out.

What is PBX?
PBX or “Private Branch Exchanges”, is a private telephone switchboard within an enterprise that allows multiple enterprise users to switch calls among them and share a certain number of external lines.

What is an Open Source PBX?
An open source PBX system is a PBX with an underlying operating system and PBX software that is made generally available to the public for free. Because the operating system and software are free, an open source PBX system is very low in cost comparing to proprietary PBX systems. It also offers unlimited flexibility to any type of business.
Types of Open Source PBX Systems
There are basically two types of Open Source PBX systems:
- “Pure” open source PBX: A PBX system that has an underlying operating system and PBX software that’s made available to the public for free under GNU General Public License. Asterisk is a popular choice of open source PBX system.
- Open source based: A PBX system with an underlying operating system and PBX software that’s open source at the core, but proprietary codes were built on top of it. Switchvox is an example of this type of PBX system.
