You can run FreeSWITCH on macOS, Linux, FreeBSD, Windows, and multiple other operating systems. It is amazing in offering omni channel communication.

It is licensed under Mozilla Public License (MPL). The original goal of Anthony Minessale to invent this VoIP technology was to build a core library for VoIP Softswitch that can be used to develop different other solutions in the IP telephony industry.

2.  History of FreeSWITCH

The world of SIP telephony originally started with the invention of Asterisk PBX, which made it possible to develop different and innovative communication solutions. Asterisk PBX had put code of the technology free as it was an open source platform.

Anthony Minessale, the original founder of FreeSWITCH open-source technology used to work in Asterisk as one of the core members. He came up with the idea of FreeSWITCH and announced this project back in January 2006. The first official version of FreeSWITCH technology was launched back in May 2008. Since then, FreeSWITCH developers and FreeSWITCH development companies have launched different versions of this technology to benefit the community.

In 2018, SignalWire Inc was founded, which is now the official company that maintains FreeSWITCH and its advancements with further version releases. Additionally, this company offers an enterprise version of FreeSWITCH and some commercial modules. There are several advantages of using the FreeSWITCH enterprise version and Commercial modules.

3.  Plus Points of FreeSWITCH over Asterisk

FreeSWITCH over Asterisk

Many service providers still face confusion when choosing between Asterisk custom development and FreeSWITCH custom development. To help you make the right choice, here are some of the criteria compared for Asterisk vs. FreeSWITCH to assure that FreeSWITCH is leading the space with its amazing features and offerings.

Architecture

FreeSWITCH used modular architecture. In simple words, developers create all functionalities in different modules, allowing easy addition and removal to form various communication solutions. On the other hand, Asterisk uses monolithic architecture. That indicates a closely coupled set of code that needs to be placed together to form a working module. This makes the development of FreeSWITCH solutions easier than Asterisk.

High performance

FreeSWITCH is a high performing solution compared to Asterisk for multiple reasons. With the similar sized hardware setup, you will receive higher, in fact, 2x times higher performance compared to Asterisk based solutions. FreeSWITCH is much better at building apps that need video and handle several concurrent calls per second.

Scalability

Due to modular architecture, FreeSWITCH development services can help you to build the most scalable communication solution. Each call instance will have independent control, which makes it easier to build scalable and stable telephony solutions, which is quite difficult with Asterisk. You will also not face any concerns and challenges that occur while developing telephony solutions with Asterisk such as race conditions, data corruption, deadlock, etc.

Multi tenancy

Again, FreeSWITCH takes over the battle because of its core libraries and architecture. It can provide the most flexible platform to FreeSWITCH developers to build highly scalable and robust solutions for multi tenant systems such as a multi tenant IP PBX system. One can also use commercial modules to develop custom telephony solutions that can easily create instances and add a role based access. Asterisk can also serve as a tool for developing multi-tenant solutions, but its architecture and lack of core libraries impose limitations.

Advanced features

FreeSWITCH is much more advanced compared to Asterisk in terms of a number of features and functionalities. It has core libraries that provide communication solutions like parallel and serial tone generation, wideband conferencing, inband DTMF generation and detection, thread isolation, and more. All these features help in building custom telephony solutions with these features. Moreover, this will also help in reducing the time and cost of development. On the other hand, Asterisk lacks some features or doesn’t have advanced features, which enforces developers to develop them from scratch. This increases the time and cost of development.

There are several other driving factors that ensure that FreeSWITCH is better than Asterisk while reviewing Asterisk vs. FreeSWITCH.
