US ENUM Trial Launches February 21; Companies Interested in Participating in the Trial Should Plan on Attending This Meeting.

DENVER -- The Country Code 1 ENUM LLC (LLC) today announced the formation of a committee to coordinate testing activities among participants in its upcoming US ENUM trial. The first meeting of this committee, to be known as the LLC's Trial Participants Advisory Committee (TPAC), will take place in Richardson, Texas, on February 21, 2006. Companies who have an interest in participating in the trial should plan on attending this meeting. Meeting details will be posted on the LLC's web site (http://enumllc.com).

The US ENUM trial will be based on the ENUM Forum's "Framework Document for a US/CC1 ENUM Trials Program," which can be found at http://www.enumf.org/home. The U.S. trial is expected to be conducted over a six-month period beginning in March.

Companies wishing to participate can fulfill one or more of the defined roles for the trial: Tier 1B Registry, Tier 2 Nameserver Provider, Registrar, Authorization Agency, Host Carrier, Application Service Provider, and User Registrant. Companies choosing to participate are responsible for their own costs and will be expected to sign a Memorandum of Understanding with the CC1 ENUM LLC, which will be available on the LLC's web site (http://enumllc.com). Several telecommunications and Internet companies have already indicated an interest in participating.

ENUM is a technology that allows users to combine the resources of the Internet with traditional telephony, uniting these two diverse worlds of communications and enabling a whole new range of communication applications. The ENUM system effectively enables individuals, businesses and other organizations to maximize the use of both the public Internet and the Public Switched Telephone Network (PSTN) by associating telephone numbers with Internet domain names. As a result, phone numbers can be used to send traditional telephony services like voice calls or faxes which can be converted to packets for delivery to a variety of devices.

On December 1, 2005, the U.S. government requested the temporary delegation of country code 1 to support an ENUM trial. That request was also supported in letters from the Canadian and Jamaican governments. Confirmation of the delegation is expected in mid-February, with the US ENUM trial expected to start in early March. During the next year, other NANP member countries may conduct national ENUM trials as well.

The TPAC will coordinate the various trial activities and report the results of the trial to the LLC, which will publish the results and report them to various governmental agencies that have been following the industry's efforts toward ENUM implementation. The TPAC will be chaired by a Project Executive to be contracted for and selected by the LLC.

Additional details and registration information for the meeting on February 21 will be posted on the LLC's web site.
