Customer Show: "The Solutions of IP Telephony" Consolidated Technologies, Inc. (CTI) hosts many events during the year that are specifically created for our customers. Here are some highlights from a few recent CTI Customer Shows on "The Solutions of IP Telephony." The shows were held at the spacious Avaya Training Center at 666 Fifth Avenue in New York City. Customers were able to interact with speakers as they learned all about the IP Telephony solutions from CTI and Avaya. They were also given an opportunity to test out the latest products for themselves in the demonstration area. One lucky attendee also walked away with a brand new Portable DVD Player.
