Consequently, no forward-looking statement can be guaranteed and you are cautioned not to place undue reliance on these forward-looking statements.

The risks and uncertainties referred to above include, but are not limited to: price and product competition; rapid or disruptive technological development, including the effects of the technology shift from traditional TDM to IP telephony; dependence on new product development; the mix of our products and services; customer demand for our products and services, including risks specifically associated with the services business and, in particular, the maintenance and rental and managed services lines of business, primarily due to renegotiations of customer contracts and changes in scope, pricing pressures and cancellations; general industry and market conditions and growth rates and general domestic and international economic conditions including interest rate and currency exchange rate fluctuations; risks related to inventory, including warranty costs, obsolescence charges, excess capacity, material and labor costs, and our distributors’ decisions regarding their own inventory level; the economic, political and other risks associated with international sales and operations, including increased exposure to currency fluctuations and to European economies as a result of our acquisition of Tenovis; the ability to successfully integrate acquired companies, including Tenovis, which has required significant management time and attention; the ability to attract and retain qualified employees; control of costs and expenses; U.S. and non-U.S. government regulation; and the ability to form and implement alliances.
