What is digital fax?
Overview
Digital fax
The evolution from analog to digital fax
Introduced in the 1980s, traditional fax technology relied on analog telephone lines to transmit document images between locations. Fax machines would scan documents, convert the image into audio tones, and transmit them through telephone lines to another fax machine that would reconvert the tones into a printed document. This process, while revolutionary for its time, had significant limitations including slow speeds, paper jams, poor image quality, and the need for dedicated phone lines.
Digital fax appeared in the early 2000s as organizations sought more efficient document transmission. Electronic fax technology converts documents to digital formats (typically PDF or TIFF) and transmits them using Internet Protocol (IP) networks. This evolution has enabled faxing to remain relevant in a digital world by addressing the limitations of analog faxing while preserving its core security benefits.
In the mid-2010s, as organizations increasingly adopted cloud computing for critical business functions, cloud fax solutions emerged. Delivering digital fax capabilities as a service, it eliminated the need for on-premises infrastructure entirely. This approach has been accelerated by the Federal Communications Commission's 2019 Memorandum of Opinion and Order 19-72, which allowed companies to decommission copper wire phone services as of August 2022, enabling organizations to transition away from analog fax lines.
Cloud fax offers several advantages, including automatic scaling to accommodate volume fluctuations, geographical redundancy for higher reliability, simplified deployment, and reduced IT management requirements. It also provides enhanced security features and better integration with modern cloud-based business applications. For organizations with hybrid work environments, cloud fax ensures consistent access to fax functionality regardless of employee location, supporting business continuity and operational flexibility.
How digital fax works
Digital fax operates on a fundamentally different technological infrastructure compared to traditional faxing, though the result—secure document transmission—remains the same. The process typically follows these steps:
- Document creation or digitization: The sender creates a digital document or scans a physical document to convert it into a digital format.
- Transmission preparation: The digital fax solution prepares the document for transmission, which may include formatting, compression, and encryption.
- Routing with internet DID numbers: Digital fax systems use internet-based Direct Inward Dialing (DID) numbers to route faxes. These virtual numbers receive incoming faxes over IP networks, replacing traditional phone lines while maintaining compatibility with legacy workflows.
- Digital transmission: Instead of using audio tones over phone lines, the document is transmitted via IP networks, which can include the internet, private networks, or cloud infrastructure.
- Secure delivery: The document is delivered to the recipient's digital fax system, email, or other designated endpoint with verification of receipt.
- Notification and storage: Both sender and recipient receive confirmation of successful transmission, and the document is stored securely according to configured retention policies.
This process eliminates the need for paper, toner, and physical hardware while maintaining the secure point-to-point connection that makes fax communications inherently secure.
Why digital fax remains critical for modern businesses
Still essential for secure communication
Despite the rise of email and digital tools, fax remains a trusted method for secure communication in regulated industries.
