Exhibit 99.1

-1- April 2007 SOUTHWESTERN SHOWCASE Investor Conference November 19, 2008

-2- Portions of this presentation contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include information concerning our possible or assumed future results of operations, as well as trends and conditions in our markets and technologies, market opportunity, and our plans regarding our business strategies. These statements can generally be identified by such words as "expects," "plans," "believes," "anticipates," “should,” “may,” “will” and similar words or expressions. Forward-looking statements are not guarantees of performance but rather reflect our current expectations, assumptions and beliefs based upon information currently available to us. Investors are cautioned that all forward-looking statements are subject to risks and uncertainties which are difficult to predict and that could cause actual results to differ materially from those projected. Many of these risks and uncertainties are described in Part I of our Form 10-K for the fiscal year ended October 31, 2007 under the heading "Risk Factors”, and in our subsequently filed quarterly reports. Some of these risk factors include: the U.S. economic crisis and its impact on capital spending trends in the Company's markets; • the Company's ability to maintain and improve upon current gross profit margins; • the success of the Mitel product and services offering; • the Company's ability to acquire and retain the technical competencies needed to implement new advanced communications technologies; • intense competition and industry consolidation; • dependence upon a single customer for the recent growth in the Company's Managed Services offering; and • the availability and retention of revenue professionals and certified technicians. Investors are cautioned that the foregoing list of important risk factors is not exclusive. These and other factors should be considered carefully and investors should not place undue reliance on our forward-looking statements. Forward-looking statements speak only as of the date made and we do not undertake to update any forward-looking statement that is contained in any communications. GAAP Reconciliation The Company uses EBITDA (earnings before net interest, income taxes, depreciation and amortization) as part of its overall assessment and comparison of financial performance between accounting periods. XETA believes that EBITDA is often used by the financial community as a method of measuring the Company's performance and of evaluating the market value of companies considered to be in similar businesses. EBITDA is a non-GAAP financial measure and should not be considered an alternative to net income or cash provided by operating activities, as defined by accounting principles generally accepted in the United States ("GAAP"). A reconciliation of EBITDA to net income is provided in Exhibit A of this presentation. Forward-Looking Statements
