5 Technical Considerations for Transitioning from TDM fax to Fax over IP

Unified Communications

When many people first here the term Fax over IP, they envision free faxing for the general public around the globe over the Internet, which is simply not the case or a driver for most businesses. With Fax over IP, we’re typically replacing legacy Analog and Time Division Multiplexed T1 telecom circuits with IP- based transports for some or all of our call legs. Migration from traditional telecom faxing (TDM Fax) to Fax over IP is dramatically increasing as IP infrastructures become more mature and SIP Trunk providers support T.38 FoIP end-to-end. There are several technical considerations for moving from a traditional “Boarded” network fax solution to an on premise or hosted “boardless” environment. This document assumes your organization has already embraced network fax server technology and demands high quality, consistent fax transport reliability better than, or at least equal to your previous TDM fax environment.



Barry University Case Study - Sagemcom-XmediusFAX

Fax Servers

“At Barry University, we recently started running Sagemcom’s XMediusFAX Fax over IP solution on Microsoft Windows Server 2008. XMediusFAX is deployed on a VMware Virtual Machine, so we did not need to purchase any physical hardware. And since it is deployed in a SIP trunking environment, no physical PRI or any lines were required. This saved Barry University from hardware installation costs and other physical limitations. Plus, our 150 users so far in the IT and human resources department love it…they can fax from anywhere using Microsoft Outlook web access. The solution is very cohesive, and works very well.

Fax Servers

These Application Notes describe the configuration steps required for the Dialogic 2000 Media Gateway telephony gateway appliance to successfully interoperate with Avaya Communication Manager and Avaya SIP Enablement Services in an Avaya SIP Telephony environment. The Dialogic 2000 Media Gateway converts signals between circuit switched and SIP enabled equipment. The compliance testing used a Nortel Meridian 1 Option 11C as the circuit switched equipment. Information in these Application Notes has been obtained through DevConnect compliance testing and additional technical discussions. Testing was conducted via the DevConnect Program at the Avaya Solution and Interoperability Test Lab.

The Dialogic 2000 Media Gateway is a telephony gateway appliance that converts signals between circuit switched and SIP enabled equipments. The compliance testing used a Nortel Meridian 1 Option 11C as the circuit switched equipment.

The test configuration consists of Avaya Communication Manager and Avaya SIP Enablement Services (SES) at the Central site, and Dialogic 2000 Media Gateway and Nortel Meridian 1 Option 11C (Meridian 1) at the Remote site. The Dialogic 2000 Media Gateway has ISDN T1 QSIG connectivity to the Nortel Meridian 1 on the one side, and SIP connectivity to Avaya SES on the other. All calls between the Central and Remote sites pass through the Dialogic 2000 Media Gateway.

A four and five digit Uniform Dial Plan (UDP) was used to facilitate dialing between the Central and Remote sites. Unique extension ranges are associated with Avaya Communication Manager at the Central site (33xxx), and Nortel Meridian 1 at the Remote site (74xx).

These Application Notes assume the SIP connectivity between Avaya Communication Manager and Avaya SES, and the ISDN T1 QSIG connectivity between Dialogic 2000 Media Gateway and Nortel Meridian 1 are already in place and will not be described. These Application Notes will focus on the configuration of the SIP connectivity between Avaya Communication Manager and Dialogic 2000 Media Gateway via Avaya SES.

CASE STUDY H.I.G. Capital SagemCom – XmediusFax

Case Studies by Vertical Market


Miami-based H.I.G. Capital is a leading global private investment firm with over $4 billion of capital under management. H.I.G.’s family of funds includes private equity, venture capital, distressed debt and public equities. H.I.G has invested in and managed more than 100 companies worldwide since its founding in 1993, with combined sales in excess of $7 billion. H.I.G. has offices in Miami, Atlanta, Boston, and San Francisco in the U.S., and affiliate offices in London, Hamburg and Paris in Europe. H.I.G.’s diverse group of strategic investors includes: Allianz AG, Credit Suisse First Boston, Deutsche Bank, GE Capital, Goldman Sachs, JPMorgan, Liberty Mutual, Morgan Stanley, and VerizonCommunications.


Fax is extremely important to H.I.G. Most of its 500+ employees are professional investment bankers involved in managing and closing multi-million-dollar transactions worldwide. They often travel for business meetings, and need access to fax documents anytime, anywhere to expedite and ensure critical transactions.  H.I.G.’s employees relied heavily on conventional fax machines, which lacked the portability and mobility required in today’s fastpaced global environment. Documents received on a fax machine at the office were useless to recipients who were traveling.

Consequently, most employees reverted to using Web-based eFax services to circumvent the imitations of traditional fax machines, which could not transmit confidential financial documents, contracts, term sheets and funding requests from anywhere, anytime. Typically, faxes can be 30 to 50 pages in length, often representing investment deals in excess of $50 million. Approximately 60% of H.I.G.’s staff used eFax accounts for online faxing.

i3 Forum Technical Specification for FoIP

Fax Servers

Problems with Fax over IP (FoIP) are experienced by all carriers and service providers in the world. While Voice over IP connections are usually set up without problems, fax connections often fail or connections are prematurely disconnected.

On the basis of two surveys that were launched between i3 forum carrier members in 2009 and 2010, it was possible to identify fax call phase and the section of the connection chain where most of the faults appear, as well as the versions of necessary standards implemented in carrier networks. Fax over IP sessions most often fail during call setup phase i.e.,, during fax discrimination, voice-fax switchover, or capability negotiations. Problems appear in gateway – gateway communication and between FoIP servers and gateways.

Information about the version of ITU-T T.38, ITU-T V.152 and other FoIP-related standards implemented in existing networks was the main assumption used in this document. Taking into account these results, this document is intended to deliver guidelines for reliable FoIP call setup in the following three areas:

  1. Specification of basic prerequisites for successful setup of fax calls over an IP link. These general prerequisites, such as necessary bandwidth, redundancy level and required network QoS, echo control, protocol stack and necessary gateway resources have been specified together with initial recommendations
  2. Guidelines for existing networks in order to take into consideration different standard version implementation. It has been considered that the significant number of different in-field implementations can make it unrealistic to define a minimum set of requirements and building a profile that could assure reliable FoIP sessions in each interconnection configuration. Moreover, fax connections are originated and terminated in service providers‟ networks which are not controlled by carriers. In this situation the guidelines for existing carrier‟s network are to:
    1. Identify the possible scenarios of FoIP connection setup
    2. Show how to search if recognised interoperability problems appear
    3. Recommend how to solve these problems. For each scenario, there are the proposals of dedicated tests that should find and eliminate all known bugs before a new interconnection link will be commercially used
  3. Analysis of the latest version of T.38, as well as related standards versions that are planned to be issued in the near future and outline their effect on the problems identified in the previous section

SIP Trunking: Deployment Considerations at the Network Edge

User Rating: / 6
FoIP Gateways

The move to Voice over IP (VoIP) and Fax over IP (FoIP) in the enterprise has, until relatively recently, been focused on communication within the private enterprise network. Now, some enterprises are using SIP trunks provided by Internet Telephony Service Providers (ITSPs) to connect their internal networks to external, public IP networks. SIP trunking is one of the first steps in an enterprise’s PSTN to VoIP transition, and it enjoys broad availability from service providers in many regions, including many incumbent PSTN service providers.

Adopting a SIP trunking service is not a simple process. In fact, many enterprises need support and guidance as they move to SIP trunking. Enterprises need a way to connect their existing voice infrastructure to SIP trunks without making major changes to their existing voice or data infrastructures. In addition, to provide the necessary protections for the enterprise, there needs to be a mechanism for implementing Network Address Translation (NAT) and firewall traversal, SIP interoperability, and network edge security; as well as a mechanism for providing a clear demarcation point or boundary for real-time IP communication services at the enterprise edge between the external and internal IP networks.

This paper provides an overview of SIP trunking and the benefits it can bring to the enterprise. It also provides information about how to address issues at the enterprise network edge when deploying a SIP trunking service.
