i3 Forum Releases Technical Specification for Fax over IP Service

April 25, 2011

The i3 Forum announced the release of Technical Specification for Fax over IP Service, Release 1.0. The i3 Forum is a collaborative communications initiative which encompasses 39 telecommunication providers that figures a combined retail base of more than 1.5 billion customers in over 100 countries.

Philippe Millet, Chairman, i3 Forum said in a statement, “Fax services at the domestic and international level are still a key source of revenue, and need to be supported in any IP voice environment.”

“As a carrier’s organization, the i3 Forum has proactively addressed the challenges and uncertainties associated with Fax over IP service to ensure reliable setup,” Millet added.

Company sources revealed that this document provides a complete set of best practices and technical guidelines that can optimize the implementation of Fax over IP (FoIP). The document, available online, will enable carriers to interconnect over IP any fax connection that originates and terminates out of their network.

Explaining the technology, officials added that fax connections are transported through IP networks either as normal voice using Voice Band Data or using fax relay technology based on ITU-T Recc. T.38 standard.

As mostly different pieces of equipment with different standard versions are implemented by different service provider networks there is a need for a Technical Specification for Fax over IP Service to avoid any hassles.

In this context, the document specifies basic prerequisites for all FoIP connections and the possible scenarios for G3 as well as for SuperG3/V.34. The specifics were drawn up after conducting two surveys which was carried out among i3 Forum carriers.

The survey results and the documents prepared by SIP Forum FoIP Task Group were leveraged to arrive at an appropriate interface configuration along with a relevant test suite. Testing will be performed when the new interconnection link in IP technology is configured, before launching for commercial traffic, added officials.

“We would like to acknowledge the fundamental contribution and support provided by the SIP Forum FoIP Task Group and SIP Forum participants. The cooperation between a carrier’s organization and FoIP solution vendors demonstrates that it is possible to bring added value to the industry on the path towards the migration to an all-IP telecom platform,” noted Millet.

In November 2010 i3 Forum announced the release of its official document titled “Voice over IPX,” which outlines the technical and commercial specifications for the Voice over IPX solution.
