In our previous article, we discussed what VoIP softswitch is and its types with their differences. When choosing a VoIP softswitch, businesses consider some important factors. In this article we are going discuss those factors and get to know the differences between open source and commercial VoIP softswitches and their benefits.

So, let’s start with open source and commercial softswitch options. Both of them have almost the same features and functionalities. So, why do you think they are separated and how do you choose the one meeting your requirements?

Let’s start digging deeper.


The most obvious difference between these two is cost. Sometimes the biggest drive to purchase open source softswitch is that it is free. Yep, absolutely free. No licensing required. Commercial software, on the other hand, requires not only to buy the software itself but also a license. Licensing is not as cheap as you’d think, the price fluctuates from several hundred to even thousands of dollars.

Open source software itself cost nothing, although you may need to cover some hardware costs. No licensing enables resellers to create their own pricing structures based on their other expenditures. For example, Asterisk has both general licensing and commercial. However, both of them have great features and functionalities.


Another big difference between open source and commercial softswitch is customization.

One of the best parts of open source softswitches is that it has community developers behind it. Anyone can add improvements to the source code. You can add as many features and functionalities as you need. In the case of open source softswitches, customization is endless.

But what refers to commercial softswitches you only get an already pre-installed softswitch and you cannot make any changes to it. It is a good option if you don’t focus on innovations. You just get a simple installation packages on existing hardware.

Root access

Open source software gives you root-level access to the entire system. This means that you can make any kind of modifications, changes, and custom integrations. And all these come without any extra charges. However, if you are not quite tech-savvy you will need an IT expert or sometimes even an IT staff to be responsible for ensuring your software is up-and-running.

In case of commercial software, you are only given access to online portal/client portal, where you can check your common operations. It will not give you access to any kind of modifications.


Here we can say that both versions give the ability to customize your dashboard or client area. You can add your logo or change colors.

Besides, you can add as many extensions and trunks as you need. With an open source version you can do it yourself, but with a commercial one you should ask your provider to do that for you.


The biggest advantage of commercial software is support. As you buy commercial software you also get technical support because it is optimized to work with specific VoIP system. Yes, sometimes it is good, when things go well, or issues are quickly troubleshooted. But in case of more complicated issues when you need a quick resolution to the issue, you should wait for the mercy of a large corporation. You just need to sit and wait as you don’t have root access to solve the problem yourself.


Both softswitches come with a wide range of functionalities and features. It is completely at your disposal which to pick and choose. Sometimes commercial versions come with a wider range of features, but with your root access you can add any add-on feature by just adding the code. Could it be easier?

VoIP softswitches have multiple functions. They are designed for billing, dialing, PBX, analyzing, SIP testing, GUIs, reporting, etc. All of them will automate a lot of manual work that you used to do: reporting, manual billing, monitoring, etc.
