INX Completes Initial IP Network for Navajo Nation; Company Helps Advance Internet to the Hogan Initiative.

HOUSTON -- INX Inc. (Nasdaq:INXI) ("INX" or the "Company") today announced the completion of the initial implementation of the first IP network for the Navajo Nation. The entire IP network of 660 phones will eventually serve all 110 chapter houses of this 27,000 square mile, three-state nation, much of which is still not served by electricity or paved roads. Cisco made the announcement at its "Connected Communities" event on Tuesday, April 18th in Albuquerque highlighting the community benefits being delivered by Internet Protocol, or IP, capabilities, to a range of public and private sector organizations.

Also present at the Albuquerque event was New Mexico State Senator Leonard Tsosie, who is a champion of the Internet to the Hogan legislation that brought the network to the Navajo Nation. (Hogan is the Navajo term for the traditional Navajo home.) "The Internet to the Hogan project seeks to bridge the digital divide in a culturally sensitive manner and tries not to leave a Hogan behind," said Senator Tsosie. "The project benefits all citizens in or near Navajo Indian country, with inferences to services for children and health care. This project has great potential for services to all citizens."

Last month, INX implemented the first chapter house to demonstrate the viability of IP Communications and kick off the Internet to the Hogan initiative. With the assistance of Cisco Systems and INX, the Navajo Nation began providing voice services over the network using Cisco Unified CallManager and Cisco Unity Voicemail servers in the central government offices in Window Rock, the Nation's headquarters. The White Rock Chapter house was the first of 110 chapter houses to receive IP telephony and video services. Residents can come to the Chapter House to make free phone calls to any other Chapter House in the entire three-state Navajo Nation because the calls travel over the IP network.

A Cisco video of the project is available on the Internet in Windows Media format at www.inxi.com/videos/NavajoWM.wmv, or in Real Player format at www.inxi.com/videos/NavajoRM.rm.

The video, along with a Press Kit of the Connected Community event held by Cisco in Albuquerque, NM on April 18th, 2006 is available at http://newsroom.cisco.com/dlls/2006/hd_041806.html?CMP=ILC-001

Mike French, Regional Vice President for INX commented, "We are excited to have hosted this kind of event in Albuquerque with Cisco Systems. It is evident from the high level representation of the Connected Communities panel that the community is embracing and investing in technology to improve the quality of life. This implementation for the Navajo Nation is a shining example of the positive impact technology can have on a community."
