When building your business communication ecosystem, it is important to consider different options to find one that fits your needs. And while there are many pre-made communication and contact center solutions, your business may need something closer to home and tailor-made for your precise needs. That’s where open-source PBX and VoIP solutions like SIP trunking come in handy.

Open-Source PBX for Business Communication

In short, open-source PBX is a free phone system available to the public. It’s usually made up of Linux OS and PBX software, which allows users to program it to meet their needs and convert computers and laptops into a business phone system.

Benefits of Open-Source PBX

Businesses with a strong in-house IT team of developers and programmers might find open-source PBX more to their liking. This is because you can tailor and customize the PBX software to fit your business needs and connect your local, remote, and distributed teams with one central hub.

There are many benefits to using open-source PBX to upgrade your business communication system. These include:

  • Substantial cost-savings
  • Easier to install and manage
  • Highly customizable
  • Phone and call management
  • Can add different communication features and tools
  • Adding cloud functionality to your communication
  • Compatible with SIP phones, IP phones, and other devices

What is SIP Trunking?

SIP trunking is a telephony solution that transmits voice communication (voice calls) from one endpoint to another. Global SIP trunks hold up to 30 SIP channels, which enable simultaneous two-way connections through a VoIP provider.

Connecting SIP to your PBX system lets you bring cloud communication functionality to your phone system as well as other voice and call features.

Using SIP Trunks with Open-Source PBX

SIP trunks can be connected to an IP-PBX system or an open-source PBX software that connects incoming calls with extensions with an organization or company. And so, if your business has direct inward dialing (DID) or a bunch of DID numbers assigned to different employees and departments, you can forward incoming calls to your open-source PBX system, and then route them as needed.

Since SIP trunks can handle multiple calls at the same time, you can turn your PBX into a full-fledged business communication system by including other necessary features and tools.

Key takeaway: An open-source PBX and SIP trunking combination lets you build communication that works for your business. With such a customizable solution, you are not stuck in rigid systems with features and services that you do not fully use. Instead, you have a system designed to maximize employee productivity and efficiency while also improving customer experience.
