What is Fax Over VOIP? Everything You Need to Know

Living in a world of e-mails and instant messaging, the concept of faxing could get out of place. However, with Fax Over VoIP, this classic way of communication just got a modern face-lift. FoIP, or Fax Over VoIP, can merge traditional fax reliability with the efficiency of internet-based communications.

Whether your industry is in healthcare, law, finance, or any that requires secure transmission of documents, Fax Over VoIP offers cost-effective, scalable, and green solutions.

Within this blog, we are going to take an in-depth tour of what Fax Over VoIP is, exactly how it works, its benefits and challenges, and why it has been an important tool for modern businesses across the globe. By the end of this blog, you’ll understand exactly why Fax Over VoIP is the future of faxing.

What is Fax Over VoIP?

If you are still wondering what this technology is, let me tell you: it is just a technology that allows fax documents to be sent and received over the Internet using Voice over Internet Protocol (VoIP) networks.

The only difference between this and traditional faxing is that traditional faxing uses analog phone lines to transfer information while FoIP converts fax data into digital packets and transfers it via the internet.

This newer approach has eliminated the need for dedicated phone lines and fax machines, which has made it a more flexible and cost-effective solution.

This technology is more useful for businesses that need to send sensitive documents in a more secure manner while leveraging their already available VoIP infrastructure.

How Does Fax Over VoIP Work?

Fax Over VoIP works by digitizing the fax transmission process. Here’s a more detailed breakdown of how it works:

1. Sending the Fax

• The user sends a fax using a VoIP-enabled device, such as an IP fax machine, computer, or mobile app.

• The fax data is converted into digital packets using a protocol like T.38, which is specifically designed for real-time fax transmission over IP networks.

• The T38 protocol ensures that fax signals are accurately converted into digital format, maintaining the integrity of the document.

• Users can also use analog telephone adapters to connect traditional fax machines to a VoIP network, enabling faxing over the Internet.

2. Transmission Over the Internet

• The digital packets are transmitted over the internet to the recipient’s VoIP system.

• The T.38 protocol ensures that the fax data is transmitted reliably, even over unstable internet connections.

• The T.38 protocol uses redundancy-enhanced critical packets and other error correction schemes, such as forward error correction, which decreases packet loss and ensures integrity in the transmission.

• Most VoIP systems would normally set QoS settings to mark the fax traffic to minimize latency and jitter; these parameters become quite critical so as to ensure performance for real-time communications of fax over a shared network.

3. Receiving the Fax

• The recipient’s VoIP system receives the digital packets and decodes them back into a fax document.

• The received fax can be printed out, saved digitally, or forwarded to an email address with much ease.

• The receiving system reassembles the incoming packets in the right order and performs error detection to ensure that the data of the fax are complete and accurate before conversion.

• Many VoIP fax solutions provide real-time delivery reports or notifications to the sender, confirming successful transmission or alerting them to issues requiring resend attempts.

Benefits of Fax Over VoIP

Fax Over VoIP offers numerous advantages over traditional faxing. Here are the key benefits:

1. Cost-Effective

• This system can eliminate the need for dedicated phone lines, reducing monthly expenses.

• Lower long-distance and international faxing costs compared to old fax systems.
