Virtual Fax Server

Virtual Fax Server

The Virtual Fax Server from Ingenium Software is a Virtual Fax Application that will operate on Windows Server 2012 R2 & Windows 2014, running on almost any virtual hypervisory software, such as Citrix, VMware and Hyper-V. Virtual Fax Server was created especially for organizations that understand the value of server virtualization and Fax Over IP (FoIP). Virtual Fax Server supports T.38 faxing over SIP and H.323 Voice Gateways. Our Virtual Fax Server is certified to support Dialogic, Audiocodes, Cisco, Avaya, Shoretel and Alcatel Voice Gateways. The Virtual Fax Server can be connected directly to a SIP Carrier such as Level 3 or fax only carrier such as etherFAX.

Any existing fax server system can be upgraded to the Ingenium Virtual Fax Server. Please contact us for a review of your current system and a price quote to get you upgraded.

Cantata Tested Interoperability

Brooktrout SR140 & TR1034 E1/T1
Cantata is continually adding IP PBX, T.38 Gateway, and other FoIP interoperability to this website. Please make sure to check back on this page for updates.

The following IP PBXs and Gateways have been tested for Interoperability with the SR140 and TR1034:


  • SR140 SDK 5.1.3 or later. (TR1034 is not compatible with VMware at this time)
  • ESX Server version 3.0.1 or later within the 3.0.x product line
  • Using the following O/S: Windows 2008 R2
  • The VMware virtual environment created for SR140 must meet SR140 minimum requirements as well as the minimum processor emulated by VMware which is the Xeon. Therefore, the minimum requirements of the virtual machine presented to SR140 are: Single Xeon – 2 GHz, 512 MB memory. This results in approximately 15% CPU utilization when running 120 simultaneous SR140 faxes.
