Faxing may be one of the oldest communication technologies, but it remains highly relevant for businesses, healthcare providers, legal firms, and enterprises that rely on secure document exchange. With the evolution of digital communication, traditional fax machines are rapidly being replaced by software-based faxing platforms that leverage VoIP (Voice over IP) and cloud infrastructure.
Among the most powerful frameworks enabling this transformation is FreeSWITCH — a robust, open-source telephony platform. Built for scalability, flexibility, and high performance, FreeSWITCH empowers developers and businesses to design multi-tenant fax solutions that are not only reliable but also cloud-ready.
At the forefront of these innovations is ICTFax, a leading FreeSWITCH-based open source fax server that brings enterprise-grade features, advanced security, and cloud-readiness to organizations and service providers worldwide.
What is FreeSWITCH-based Fax Software?
FreeSWITCH-based fax Software is a faxing solution developed on top of the FreeSWITCH telephony framework. It enables the transmission of faxes over IP networks (FoIP – Fax over IP) using T.38 and G.711 protocols.
Unlike traditional fax machines that rely on telephone lines, FreeSWITCH Fax Software leverages VoIP technology to:
- Send and receive faxes over the internet
- Integrate with email, CRMs, and business applications
- Support multi-tenant deployments, allowing multiple organizations to use the same platform independently
- Scale seamlessly in cloud environments
In simple terms, FreeSWITCH-based fax Software transforms faxing into a modern, digital, and secure communication service that fits the needs of today’s enterprises.
Why Businesses Still Need Faxing
Faxing continues to be important in many industries because of:
- Legal Validity – Many industries still recognize fax as legally binding.
- HIPAA Compliance – Essential for healthcare providers handling patient data.
- Security – Less prone to phishing and spam compared to email.
- Reliability – Provides delivery confirmation and audit trails.
ICTFax ensures organizations can continue faxing with modern, compliant, and efficient technology.
