The slowing economy is certain to play a role in the continued deployment of VoIP. While new entrants may be skeptical about spending in order to save, this might not be as much the case among the increasingly sizable base of existing business VoIP users who still have plenty of legacy TDM voice solutions in place. Many of these decision makers are more likely to seek solutions involving less up-front costs, or rock-solid financials than those choosing to abandon further deployment strategies. Only 34% of businesses with VoIP use it exclusively (no TDM). Deployments remain wide-ranging, and despite recent economic slowdowns, growth in all flavors of VoIP is expected to grow at mitigated levels, reaching 74% of all US businesses by 2012.
　　This report reviews the key factors driving VoIP adoption, the impact of a slowing economy, and the multiple flavors of IP finding roots in the US business market. Survey results of 639 decision makers in organizations that have adopted VoIP are reviewed. Revised line/seat and revenue forecasts through 2012 for Hosted IP Centrex and broadband IP telephony within the US are provided, along with a worldwide IP PBX line.
