FreeSWITCH was initially conceived by Anthony Minessale to create a core library for VoIP Softswitch. This visionary technology aimed to furnish the IP telephony industry with versatile solutions beyond mere Softswitch functionalities.

2. History of FreeSWITCH

When you start acquiring knowledge about FreeSWITCH technology and FreeSWITCH conferencing solution development, it is mandatory to take a quick look at the history and evolution of the technology. Therefore, let’s take a quick look at the evolution of FreeSWITCH.

The evolution of FreeSWITCH began with the foundation of Asterisk PBX. It pioneered SIP telephony solutions and enabled innovative communication developments. Initially, Asterisk PBX embraced open source principles, making its code freely accessible.

Anthony Minessale, a former core member of Asterisk, conceived the idea for FreeSWITCH. He and some of his colleagues unveiled the project in January 2006. By May 2008, the first official version of FreeSWITCH was launched for users. Certainly, it was marked as a significant milestone in its evolution. Since then, FreeSWITCH developers and development companies have continually released new versions to enhance their capabilities and serve the community.

In 2018, SignalWire Inc. was established as the official steward of FreeSWITCH. Since then, the official team has been overseeing its development and introducing further advancements through subsequent releases. This initiative also introduced an enterprise version of FreeSWITCH along with commercial modules, offering additional benefits to users.

In short, FreeSWITCH is much more advanced and potent now. Therefore, it is a useful technology to develop any custom telephony solution. From VoIP Softswitch solutions and SIP Softphone apps to IP PBX solutions and call center software, development using this technology covers endless possibilities for organizations looking to revolutionize their communication infrastructure.

3. Plus Points of FreeSWITCH Over Asterisk

Asterisk and FreeSWITCH are two popular technologies that are used in the process of developing different communication and collaboration solutions. Certainly, both of these technologies have their own pros and cons. Therefore, the decision between Asterisk and FreeSWITCH for custom software development of telephony solutions often leaves service providers in a predicament.

Certainly, based on our experience, we count on FreeSWITCH. However, to help you make the right choice and aid in this decision making process, let’s conduct a thorough comparison of Asterisk and FreeSWITCH. This section of comparison between Asterisk and FreeSWITCH clarifies the remarkable features and offerings that position FreeSWITCH at the forefront of the industry.

FreeSWITCH takes pride in having modular architecture. Undoubtedly, it is a paradigm wherein developers add functionalities within distinct modules. This modular approach facilitates seamless integration and removal. Therefore, it empowers the creation of diverse communication solutions with unprecedented ease.

Conversely, Asterisk adopts a monolithic architecture. Therefore, it necessitates the amalgamation of tightly coupled code segments to form functional modules. Indeed, this architectural disparity significantly streamlines FreeSWITCH compared to its Asterisk counterpart.

Performance: Defining the Benchmark

FreeSWITCH stands as a benchmark of efficiency in the development of any VoIP solution such as FreeSWITCH development services. FreeSWITCH boasts about performance metrics that outshine Asterisk on multiple fronts. With similar hardware configurations, FreeSWITCH delivers a staggering twofold increase in performance compared to Asterisk based solutions. Its ability to handle video and manage multiple concurrent calls per second emphasizes its superiority in various telecommunication applications.

Scalability: Building for Tomorrow

Undoubtedly, the core USP of FreeSWITCH is its innate scalability. The modular architecture of FreeSWITCH facilitates its exceptional scalability. This architectural foundation empowers development services to build highly scalable communication solutions. Certainly, in these solutions, each call instance enjoys independent control. As a result, it is a development environment conducive to the creation of scalable and stable telephony solutions.

Conversely, this is an element often vague in Asterisk that weakens the development cycle. Moreover, Asterisk has further challenges that are evidently absent in the FreeSWITCH technology. For example, race conditions, data corruption, and deadlock are prevalent in Asterisk. However, these issues are not part of FreeSWITCH.

Multi Tenancy: Versatility and Flexibility

The core libraries of FreeSWITCH and architectural flexibility render it as a prime candidate for the development of robust solutions tailored to multi-tenant systems. Undoubtedly, FreeSWITCH is an important technology for the development of multi tenant solutions. For example, FreeSWITCH conferencing solution development with multi tenancy has FreeSWITCH as the prime technology to choose from. FreeSWITCH is augmented by commercial modules of SignalWire. Therefore, it empowers developers to effortlessly add instances and implement role-based access.

Unquestionably, the level of flexibility and versatility of FreeSWITCH is way superior to Asterisk. While Asterisk may serve as a tool for multi-tenant solutions, its architectural constraints and dearth of core libraries invariably limit its potential. Therefore, FreeSWITCH wins the game here.

Advanced Features: Redefining the Future of Telephony

FreeSWITCH distinguishes itself through its advanced features and functionalities. Certainly, it sets new benchmarks in the development of telephony solutions. Certainly, core libraries facilitate parallel and serial tone generation, wideband conferencing, inband DTMF generation and detection, and thread isolation. It is a suite of capabilities that expedite the development of custom telephony solutions. FreeSWITCH reduces development time and costs due to its powerful features and functionalities

These advanced features underscore the dominance of FreeSWITCH over Asterisk. Often, this necessitates feature development from scratch.

In conclusion, FreeSWITCH emerges as the preeminent choice over Asterisk. It characterizes unparalleled performance, scalability, versatility, and advanced features. Therefore, FreeSWITCH evidently demonstrates its enduring dominance in the telephony industry over Asterisk.
