FreeSWITCH was designed by several former developers of the popular Asterisk open source PBX and was created to address the drawbacks of proprietary solutions with a focus on key design goals such as stability and scalability.


Today, FreeSWITCH is used by thousands of businesses from all corners of the globe in a range of industries, including carriers, communication startups and enterprise businesses. At its core, 

FreeSWITCH is a scalable and multi-platform soft-switch or PBX and it is capable of handling thousands of simultaneous calls. The telephony platform facilitates the creation of voice, chat, and video applications, via phones and web browsers. FreeSWITCH can be used as a stand-alone system or it can be combined with a user interface, such as FusionPBX, to enhance functionality and usability.


FreeSWITCH includes a robust fax server that provides complete T.38 support and can be used to send and receive faxes directly. Or it can be used in pass-through mode by acting as a conduit between the carrier and a fax machine with an ATA. But the challenge to achieving successful Fax over IP (FoIP) is finding a SIP trunk vendor that offers reliable T.38. Luckily, faxing over our Power-T.38 SIP trunks is just as reliable as traditional phone line faxing. Simply activate with us, connect our SIP trunks to your FreeSwitch server, and see how well the faxing works!


FreeSWITCH has been thoroughly tested by our support engineers and has been proven to work seamlessly with our Power-T.38 service. We’ve gathered screen shots and recommended best practices and assembled them into our FreeSwitch Knowledge Base Article, which you can find here:
