AMTELCO installed its first Electronic Video Exchange (EVE) system at Spectrum Communications, located in Wauwatosa, WI in May, 1983, and debuted its new product at the Associated Telemessaging Services International (ATSI) meeting in June of that same year.

The following year the number of EVE system installations increased, and the new owners gathered in St. Louis, MO to network and discuss what additional features might be added to the EVE system to make it stronger. These discussions included John Morley, the original architect of the EVE system.

As the group of owners had grown to 50 strong and at their next meeting in 1984 it was decided to formalize the group and appoint a board of directors.

The organization was officially named National Association of EVE Owners (NAEO) and volunteers handled all functions of the organization.

Subsequent annual meetings included AMTELCO representatives, and owner-members brought "Wish List” items to the meetings for consideration by AMTELCO. Those wishes that were deemed possible were implemented – making the EVE platform increasingly powerful.

In 1988, Joe Everly and John Morley of AMTELCO debuted a brand new concept in tele-messaging, a PC-based open architecture system called PCMX. This paperless messaging system included an integrated voice mail system, allowing owners to enjoy the efficiencies of maintaining a single system. The users of both PCMX and EVE joined forces and renamed the organization National AMTELCO Equipment Owners, maintaining the NAEO name.

In 1993, AMTELCO introduced its new Infinity system, which integrated paperless messaging and voice processing with a significantly larger account capacity.

In 2003, the Intelligent Series (IS) module was added to the Infinity platform offering script-based message services – a major development in the industry.

Now, in 2017, the new products in production are Genesis and MergeComm. NAEO continues its tradition of working closely with AMTELCO to make all of the AMTELCO product offerings as strong and valuable to the industry as possible.

Current members of NAEO are comprised of Infinity, IS and Genesis users. The organization now includes a combination of owners, managers, IT specialists, and others who work closely with the AMTELCO equipment to ensure a smooth running call center.
