Fax Over IP

What is Fax Over IP?

FoIP or Fax over IP (also known as virtual fax) refers to the method and technology of sending fax documents over an IP network (local or wide area). This is different from the way faxes have traditionally been handled. For years the sending and receiving of fax documents have been handled over the PSTN or Publicly Switched Telephone Network. With Fax over IP fax documents by-pass the PSTN completely. This is similar to how VoIP (Voice over IP) works but requires additional network bandwidth due to the increased size of fax documents.

It has taken the unreliability of faxing out of the equation and revolutionized the transmission of information through faxes. Now, faxes can be sent from fax machine to fax machine, fax machine to email, or vice versa. FoIP allows the smooth transition between technologies, as old numbers and communication methods can be kept while eliminating unnecessary overhead. Just ensure there is enough bandwidth and the benefits speak for themselves.

How does it work?

The concept behind FoIP is pretty straightforward, especially for those that understand VoIP already. The fax is first packetized as an image and sent from point A to point B in transport protocol. Sending with FoIP works via T38. This is a protocol that describes how to send a fax over a computer data network, and for it to work requires a T38-capable VoIP gateway as well as a T38-capable fax machine, fax card or fax software. Fax Server software that can talk ‘T38’ allows the great Unified Communications feature, Fax to Email, which sends faxes directly via a VoIP gateway and converts the fax message into an email. The plus side is that no additional fax hardware is needed for the Fax to Email feature to work seamlessly!

  • UNIFIED NETWORK CONNECTIVITY – Fax over IP leverages your existing LAN and WAN IP networks.
  • ADVANCED MANAGEMENT – Bringing fax documents into IP realm allows for fax documents to be easily archived, sorted and emailed.
  • LOWER COST – With one less network to pay for and manage there is a definitive cost savings in using Fax over IP.
  • REMOTE USEAGE – There are many locations throughout the world in which a fax line cannot be provisioned. In such areas FoIP is the answer.
