IT Services' IP Telephony-Related Growth Remains Strong Through 2007 (Executive Summary) Buyer Behavior Gartner Dataquest believes the market for IP telephony products and IT services has reached an inflection point. Increasing numbers of announcements by vendors and external services providers for large commercial and public sector network convergence projects point to decreasing market skepticism and inertia to accept Internet Protocol telephony. In fact, IP telephony is only two to five years away from broad acceptance, as showninfigure1.

This forecast considers IT services surrounding IP-enabled private branch exchanges (PBXs) and key telephone systems (KTS) and pure IP PBX/KTS within the customer premise equipment environment. The forecast also draws revenue associated with IT services related to upgrades in LAN and WAN to accommodate IP telephony migration (see Figure 2). Figure 3 shows IT management and development and integration services will exhibit the strongest growth through 2007 at 48 percent and 46 percent respectively. 2003 Gartner, Inc. and/or its Affiliates.

IT Services' IP Telephony-Related Growth Remains Strong Through 2007 (Executive Summary) 3 Driver and Inhibitors The market for IP telephony is being driven by the following hard and soft metrics: Increase return on investment for product and IT services Decreased total cost of ownership for network infrastructure acquisition and management Improved and enhanced enterprise communications processes Creation of new business opportunities and communication services What enterprises will be faced with in the two- to five-year interim is how to time their migration to an IP telephony infrastructure. Table 1 provides an estimate of migration costs to the enterprise LAN to support IP telephony. The assumption is that the older the LAN infrastructure is, the more costly the migration to IP telephony will become.

Potential cost savings associated with in-house management and maintenance contracts promotes the adoption of IP-PBX systems. An increase in the number of knowledgeable IT workers will encourage adoption. IP phone and PBX and IP-PBX equipment prices are expected to drop. Long Term Voice and data equipment purchased at the height of the technology boom during the late 1990s will be ready for replacement during the next two to threeyears.itiscost-effectivetoreplacethetraditionaltelephonyinfrastructure with IP components because the traditional components need to be replaced. Vendors may phase out traditional PBX/key telephone system equipment lines, forcing some users to migrate toward IP-enabled or pure IP-PBX systems, even though a business case may not necessarily justify the conversion. 2003 Gartner, Inc. and/or its Affiliates.

4 IT Services' IP Telephony-Related Growth Remains Strong Through 2007 (Executive Summary) Forecast Inhibitors Channel improvements in understanding how to sell and support converged voice/data equipment are expected to improve the sales processes associated with some IP-enabled and pure IP-PBX sales. Short Term Challenges with distribution channels understanding how to sell and support converged IP-PBX equipment will delay some wide-scale adoption of converged equipment internationally. The substitutions of voice services, such as traditional analog telecommunicationsservicesandgrowingmobiletelephonyarereducingprice,which contributes to a constrained adoption timeline of IP telephony. Government regulation regarding toll arbitrage in regions such as Latin America protects government telecommunication providers and monopolies at the expense of IP telephony. Security concerns about eavesdropping on IP-enabled phones are not adequately addressed. Long Term Development of applications for IP-enabled systems has been slow and has yet to differentiate IP-enabled systems from traditional telephony systems. Infrastructures on many LAN and WAN sites throughout the world fail to consider IP voice traffic support. This means most users must spend large sums of money during the next several years to prepare their networks for IP-PBX equipment. Incompatibility of IP telephony equipment across the manufacturer landscape. Enterprises need to purchase all equipment from a particular vendor instead of being able to select the best pieces from individual vendors.
