Many businesses with existing VoIP capabilities chose to spend 2009 fortifying the proportion of their total voice capabilities dedicated to IP. This was often at the expense of expanding VoIP capabilities to new locations. In-Stat now finds that 41% of businesses with VoIP capability have no legacy TDM voice services, vs. 34% in 2008. 42% of US businesses now have a VoIP solution in at least one location.

Hosted IP services such as IP Centrex and Broadband IP Telephony saw steady growth in 2009, while IP PBX growth was significantly stunted. While there are indications that the economy and high-tech investments are in slow recovery, IP equipment investments are likely to lag other areas. 

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 1,000 decision makers in organizations that have adopted VoIP are reviewed. Line/seat and revenue forecasts through 2013 for Hosted IP Centrex and broadband IP telephony within the US are provided, along with a worldwide IP PBX line forecast.

米国ビジネス市場でのVoIP普及率は2013年までに79%の予測

アリゾナ州スコッツデール、2010年2月2日
米国のビジネス市場におけるVoIPの普及は、今後2、3年間で急速にすすみ、2009年末の42%から2013年には79%へと増加するだろうと米国調査会社インスタット社は報告している。

「VoIPの採用企業は、VoIPのコスト節減の効果をよく知っており、効率化とコスト削減のために、従来型のTDM音声ソリューションをVoIPに置き換えることで、限られた予算を配分している。近年は、新規オフィスの開設が少ないが、このような短期投資の多くは、効率とコスト削減が最大になる本社で行われている」とインスタット社のアナリストDavid Lemelin氏は語る。

インスタット社は、下記についても調査した。

• ホステッドIPセントレックスは、既にブロードバンドIP電話を上回り、最も収益が高い、キャリアベースのビジネス向けVoIPソリューションとなった
• 既にVoIPソリューションを採用している企業の33％が、昨今の経済状況によって追加的な採用計画を遅らせており、計画を変更しないとしている企業は30％であった
• ブロードバンドIP電話の収益は、成長し続けており、2013年には2008年比で倍増以上となるだろう。これは、ますます分散化やモバイルを利用する社員が増加するために、シングルユーザーアプリケーションが促進することによる

VoIP Penetration Forecast to Reach 79% of US Businesses by 2013

SCOTTSDALE, Ariz., February 2, 2010 - VoIP penetration among US businesses will increase rapidly over the next few years, reaching 79% by 2013, compared to 42% at the end of 2009, reports In-Stat. This penetration reflects companies having a VoIP solution deployed in at least one location.

“VoIP adopters have a good understanding of the cost savings associated with VoIP, and have oriented their limited budgets to optimizing efficiency and savings by replacing legacy TDM voice solutions,” says David Lemelin, In-Stat analyst. “With businesses opening up fewer new locations than we have seen in recent years, much of this current investment is occurring at headquarters locations where efficiencies and savings can be maximized.”

Recent research by In-Stat found the following:

• Hosted IP Centrex has now surpassed Broadband IP Telephony as the leading revenue-generating, carrier-based business VoIP solution.
• 33% of businesses that have already deployed VoIP solutions report that recent economic conditions have caused them to slow additional deployment plans, compared to 30% reporting no change in plans.
• Broadband IP Telephony revenues continue to grow and will more than double by 2013, compared to 2008.  This growth will be fueled by single-user applications among increasingly distributed and mobile workforces.

Recent In-Stat research, US Business VoIP Overview: Optimization Trumps Expansion (#IN1004350CT), covers the US business market for IP telephony. It includes:

• Examination of the US business market for IP telephony based on survey results of 1000 US business decision makers currently using VoIP.
• Worldwide IP PBX line shipment forecast 2007–2013.
• US Hosted IP Centrex seats in service forecast 2008–2013.
• US Hosted IP Centrex revenues forecast 2008–2013.
