A True Story

A developer with a major network-equipment OEM called this morning with a hosted-fax requirement to upgrade his UC offering. The call turned out to be something of a deep-dive into his requirements since Commetrex offers so many alternatives, all of which can support the stated requirements. The best choice, however, would not only provide the required function and performance, but would meet more strategic requirements, as well.

  • A complimentary fit with the legacy product line True Story
  • A fit with available development resources
  • Time-to-market
  • Required investment
  • Support

Certainly, BladeWare Fax-to-Email and Email-to-Fax would meet the fundamental requirements, but often UC systems require a tight integration between the vendor’s proprietary UC application and the fax send-receive resource. Except for integrating with the subscriber database, these two BladeWare products are stand-alone systems. Since E2F and F2E are applications hosted by the BladeWare value-adding platform, the OEM can reduce recurring cost by developing his own applications, saving money on BladeWare’s license fees, but also increasing the up-front investment and time-to-market.

Further requirements discovery could reveal a need for a strategic platform developed and controlled by the OEM. In this case, SIPfaxEngine or Multi-Modal Terminating Fax (MMTF) would be his best choice. These licensed software products would give the OEM the industry’s premier fax technologies and complete control of the product since these products are licensed as source code.

In addition, there’s the IP Multimedia Subsystem (IMS) architecture, which accomplishes much the same things as SIPfaxEngine, but with less integration effort. BladeWare Fax Media Server (FMS) utilizes MSCML, a standard protocol that allows a SIP server to outsource all fax transactions to an ancillary processor, as shown above.  With Media-Server Command Mark-up Language, the application server, which hosts the OEM’s proprietary applications, to fully and easily command and control BladeWare FMS to send and receive all faxes.

The Fax Is In the Details

Product developers, we have a problem! Something is not working. Why? Well, fax was not designed for use over IP. So, the developers of IP products and services must invest substantial resources to develop reliable Fax over IP (FoIP) products. Fortunately, FaxTap NG is there to help.

Developing, compiling, testing, and analysis for G.711 modemFaxTapNG Pic pass-through calls and T.38 can be a costly and time-consuming process. Other software solutions such as Wireshark do not support analysis of G.711 modem pass-through calls. For example, Wireshark may mis-identify packets following a T.38 re-invite as T.38, even if they are RTP, and can lead to misinterpretation and flag them as “Malformed T.38 packets”. It may interpret HDLC image frames during ECM transmissions as if they were T.30 negotiation frames. Wireshark has limited T.30 protocol analysis, and it does not render the image for the user. FaxTap NG picks up where Wireshark leaves off.

With Faxtap NG, OEMs can efficiently and effectively develop FoIP-capable products utilizing the following features:

  • Imaging rendering
  • Post real-time decoding
  • DLL/SO (OEM) or end-user versions
  • Comprehensive session analysis
  • Bad-line repair
  • SIP ladder diagram output
  • T.30 ladder diagram output

With end-user, corporate, and OEM licensing, FaxTap NG can meet your needs. Contact us to learn more here.

Lawful Intercept for Fax

Lawful Intercept (LI), mandated by law in nearly every county, requires that operators provide electronic surveillance of communications when requested by a law-enforcement agency (LEA). As communications services proliferate and become more complex, the global LI market is experiencing rapid growth for LI systems and services. Orbis Research, for example, forecasts the global LI market at $1.3-billion by 2019, with a CAGR of 24% through 2021.

The Communications Assistance for Law Enforcement Act (CALEA), passed by the U.S. Congress in 1994, stipulates that operators must facilitate the monitoring of IP communications.  CALEA sets the primary requirements; industry standards bodies specify detailed requirements, such as the interfaces between the operators and the intercept requestor. Standards organizations active in this area include American National Standards Institute (ANSI), Telecommunications Industry Association (TIA), ETSI in Europe, and Alliance for Telecommunications Industry Solutions (ATIS).

Why bring this up? You may be aware that FaxTap NG, Commetrex’ fax-analysis and rendering tool, is used by service providers and OEMs to diagnose problems with TDM and IP faxes. But it’s also available in an OEM version for use by the LI OEM.

Fax data are delivered to the LEA along with all the other designated data scooped up by the operator’s LI system. But, unlike a voice stream, which usually needs no post-processing, a fax session must be analyzed by a sophisticated rendering tool. This means the LEA must either have the rendering software or outsource the service.

FaxTap NG does that, including:

  • Speedier time-to-market
  • Lowering of development costs
  • Meeting of standards requirements

Include FoIP in Your MFP

While faxes may seem to be a thing of the past, many industries have maintained that they are the only accepted transmission of signature documents. So, just give me the Fax over IP (FoIP), and nothing but the FoIP. By adding FoIP in Multifunctional Peripherals (MFPs), OEMs can expand their target markets beyond printers, scanners, and copiers to include TDM and FoIP.

“CCS Insight expects 124-million printers to be shipped worldwide in 2018, up from 106 million in 2013, increasing at a compound annual growth rate (CAGR) of 3.1% during that period. Inkjet multifunction printers will remain the largest segment, accounting for over 50% of total shipments.” Many of these products would benefit from an all-software fax feature.


By adding SIPfaxEngine from Commetrex, the industry’s most-advanced core analog-technology bundle, OEMs can simplify the addition of comprehensive FoIP support. OEMs such as Dell, Kyocera, Konica Minolta, Toshiba, IBM, and others can add a full-function SIP and fax-technology foundation for multi-function printers, media servers, fax terminals, and analog devices.
