Fax Over IP

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


FaxCore provides users with a collection of the newest and most inventive fax technology available today. Customers can choose from our A-LA-CART list of individual components to build a custom solution that fits their specific requirements or select from our extensive list of appliance-type product bundles.

The A-LA-CART is particularly suitable for organizations that may want to replace an existing fax server solution and already have fax boards or FoIP fax drivers already in place. These organizations can simply select the modules they need to migrate to a true 21st Century fax server application – FaxCore

For customers that prefer an appliance-type solution, FaxCore offers a range of products to fit almost any environment. These units consist of pre-assembled appliance options complete with remote installation and annual support and maintenance bundled into a single product bundle. The appliances support analog, digital or FoIP deployments, integration with VoIP PBXs and even include virtual appliance options.


FaxCore is a true 21st Century fax server application with a mix of standard features unparalleled in the industry. Built on the Microsoft .NET Framework 4.0 the FaxCore high-performance engine is designed to deliver fax traffic over enterprise networks of any size. FaxCore lets you fax enable the entire organization locally or globally.

Total Fax Tracking
Modeled after the browser-based tracking systems used by top companies, FaxCore tracks incoming and outgoing faxes before, during and after transmission including confirmation, time of delivery, undeliverable notification, alternate fax numbers, transmission replay and much more.

Automatic Archiving.  FaxCore offers the most powerful document archiving available. Incoming faxes are immediately stored, indexed and can be retrieved with any web browser as JPEG, GIF, PDF or TIFF files.

Integration with Microsoft Applications.  FaxCore is integrated with many Microsoft applications, such as Microsoft SQL Server, Exchange and SharePoint without cumbersome connectors. The product runs on Microsoft Server 2008 R2 and is interoperable with Exchange 2010 UM for the latest in Unified Communications (UC) technology.

Microsoft CRM integration.  Fax directly from MS CRM and log all fax communications into the history file for each Company or Customer record. Send and receive faxes from CRM as easily as emails.

Fax-enable Applications.  Leveraging our .NET architecture and Web Service/SOA SDK, developers can easily fax-enable CRM, ERP, EMR and office productivity software with only a few lines of code.

SMTP Gateway.  Supports character encoding when parsing sender and recipient email address from mail server. This allows SMTP parser to convert double-byte characters from base64 string to original character encoding.

New Rendering Engine.  The new rendering engine eliminates the requirement for native applications including Microsoft Office and Adobe Reader installed on FaxCore Server.

Server Architecture

The FaxCore Server is architected with the same web-server-farm design that popular on-line retailers use to provide scalable and fault tolerant high volume Internet based services. This allows FaxCore to provide near linear n-tier scalability and complete fault tolerance, without the need for complicated clustering software or network configurations that are often required from traditional client-server based fax software.

Key features of the FaxCore Server architecture include:

N-tier scalability: FaxCore’s web architecture provides the scalability and fault tolerance demanded by organizations today through open and proven web-server-farm architectures. New FaxCore Servers can be added and removed to an organizations global network on the fly without needing to shut-down the system.

Open MS SQL Database: FaxCore Standard ships with a SQL Express and FaxCore’s Enterprise Server includes a MS SQL server. FaxCore can also run as an instance on existing corporate MS SQL servers.

Intelligent Server Discovery and Monitoring: All FaxCore servers, services, and related Fax Boards register with the central FaxCore Database each time they start-up, without the need to pre-define the server through administration screens. Once a server registers, in can be monitored and administered through the FaxCore administration web pages.

Powerful Document Server: FaxCore includes a lightweight document server that gives you precise control on where documents are stored on your servers. Inbound and outbound faxes can be automatically partitioned by FaxCore the way you want them on your drives, allowing simple archiving and intelligent file naming.

Microsoft .NET: FaxCore is built natively using Microsoft .NET technologies and provides powerful SDKs for both native .NET development, and XML based web service interfaces.
