FreeSWITCH is a communication software solution used for voice and messaging applications. It is a free and open-source communication software solution licensed under Mozilla Public License. Using FreeSWITCH, we can build PBX, softphone, and Softswitch. FreeSWITCH uses Sofia Sip stack this stack is fully mature robust and complete. FreeSWITCH is written in C language. We can run FreeSWITCH on different Linux flavors, Mac OS X, Window, ARM.

A lot of open source communications software available such as Asterisk, FreePBX, Jitsi, sipXec each of them has advantages as well as some disadvantages, but I prefer FreeSWITCH among these due to its quality and reliability which influenced me a lot. That's why I am writing this article. Now I discuss some features in FreeSWITCH which make me a fan of FreeSWITCH.

Completely Designed
The design of any application creates a very great impact. The most impressive thing which I found in FreeSWITCH is a design that we can modify easily according to our needs. The developer of FreeSWITCH spends a lot of time designing this software and write deep detail which helps to understand this open-source communication software's functionality. Freeswitch is designed in such a way that it has different telephony features like IVR and call control.

Flexible
Flexibility is another major reason for choosing FreeSWITCH. FreeSWITCH has the flexibility to load scripts written in different languages. We can upload scripts written in PHP, Lua, Python, XML, and Perl. FreeSWITCH provides a lot of flexibility and freedom to mold your VoIP software. We can integrate or embedded FreeSWITCH with other projects and also use it as a stand-alone application.

Quick Responsive Community
Almost all open-source projects have a support community. Support community plays the role of backbone in open source projects. Member of community plays various roles develops new features, bug fixing, and problem-solving. I found the FreeSWITCH support community highly professionals, friendly, supportive and quick responsive community. FreeSWITCH mailing list support community is very quick you get the answer to your problem within few hours, I appreciate this quick responsive supporting community. People who want to implement the FreeSWITCH telephony software solution but have less knowledge can get the benefits of their paid consultancy and support.
