Fax over IP (FoIP) refers to the process of sending and receiving faxes via a Voice over IP (VoIP) network.

Traditionally network fax users were forced to install fax boards in their servers to allow them to communicate with the public switched telephone network (PSTN). After the introduction of VoIP networks and the subsequent development of FoIP software you no longer need to install fax hardware to utilise a network fax server. Instead you now have the option to install FoIP drivers such as Dialogic SR140 on your fax server which allows the initial part of the fax call to traverse your IP network using SIP or H323. Typically the IP call will then terminate onto the PSTN via an IP-PBX or a VoIP gateway.

  • Eliminates hardware dependency allowing fax server virtualisation
  • Takes advantage of existing IP infrastructure
  • Lowers total equipment, maintenance and operating costs due to network consolidation
  • Reduces long distance costs and eliminates the need to maintain fax ports on your PBX system

Traditional Fax Server

In the past deploying a fax server meant new server hardware, new fax hardware and new telephone lines 


Fax Over IP Server

With FoIP software drivers you can now use existing server and IP infrastructure to deploy the fax server software
