FaxCore web interfaces are available for the following browsers:

  • Microsoft Internet Explorer
  • Google Chrome
  • Mozilla Firefox

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.

System Requirements

Minimum Recommended Requirements

  • Windows Server 2008, R2 or Server 2012
  • CPU: Pentium 4 (2.0ghz or higher)
  • Memory: 4 GB RAM (Minimum)
  • Disk Space: 20 GB available disk space
  • (Additional disk space will be required for storage of fax messages)

FaxCore Services

The Faxcore Server is comprised of a set of Windows Services that work together to process messages in Faxcore. The primary services are:

  • FaxCore FaxAgent: Communicates directly with intelligent fax cards, FaxCore FoIP Drivers to send and receive faxes and secondary driver instance for fail-over/overflow configuration with etherFAX.
  • FaxCore Renderer: Provides high performance server side rendering of common desktop document formats including Microsoft Office, HTML, PDF, etc. Total overall in excess of 200 formats.
  • FaxCore Database: A MS SQL or SQL Express Database engine that stores both the FaxCore repository (domains, users, configuration settings, etc), as well as the transactional data of messages sent and received through FaxCore.
  • FaxCore Website: Microsoft IIS web application providing end user and administrator interfaces via a web browser.

FaxCore Partitioning

Faxcore allows partitioning of these services across any/all servers in the Faxcore network – providing an unlimited number of configurations to meet the specific fault tolerance and scalability requirements of each customer’s unique usage profile. For example, customers using primarily server side rendering of user documents can separate the Faxcore Rendering service onto its own set of servers in order to remove some of the load from their Faxcore servers that are sending/receiving faxes through the FaxAgent service.

FaxCore Administration and Monitoring

Faxcore provides central administration and monitoring of all servers, services, and application queues through intelligent web browser interfaces. Administrators can see exactly what is happening in the system and exactly what messages are currently being processed.

Intelligent Fax Boards, FoIP Drivers

FaxCore supports intelligent fax boards, T.38 FoIP drivers, media gateways, analog telephone adapters (ATA) and other fax or telephony related products from leading manufacturers. The particular product or combination of products FaxCore recommends will depend on the customer environment. For example, customers wanting to integrated their VoIP PBXs from companies like Cisco, Avaya or ShoreTel would be required to use fax products, like FaxCore, approved by those vendors. Be assured that all products recommended by FaxCore are from the industry’s leading vendors.

The product selection offers both TDM and IP-based fax capabilities for network-based fax applications and integration with document management and business process automation systems. As companies are migrating to VoIP networks, the versatile FaxCore product selection provides an easy migration path from traditional TDM-based fax systems to hybrid and all-IP fax systems.
