Infonetics Research: SIP trunking on the rise - new survey

BOSTON, MA--(Marketwire - October 27, 2009) - Infonetics Research,, published a new report, SIP Trunking Deployment Strategies: North American Enterprise Survey, which polled purchase decision-makers at medium and large companies about their use of PBX trunking services.

The survey, part of Infonetics' Enterprise VoIP and Unified Communication Continuous Research Service (CRS), asked companies about their use of PBX manufacturers, trunking services, providers, and expenditures, and takes an in-depth look at why organizations are deploying SIP trunking (or not), what criteria are used to select SIP trunk service providers, how and where SIP trunks connect with the existing infrastructure, and what expenditure savings they obtained.


"Many companies have already deployed VoIP internally, but they usually use legacy TDM technologies to connect to the PSTN. In our latest study, we finally see this changing: SIP trunking is catching up with TDM services and gaining broad traction with buyers, driven by their desire to lower their overall trunking expenditures. However, it is unlikely we'll see a rush towards SIP trunking, as SIP trunks are usually implemented during general technology upgrades, which are on hold at many companies right now," notes Matthias Machowinski, Infonetics Research's directing analyst for enterprise voice and data.


-- The typical survey respondent organization spends between $100 thousand
   and $500 thousand per year on trunking services

-- T1 lines are still the most commonly used trunking service used to
   connect to the publicly switched telephone network (PSTN), but native
   VoIP trunks are on the rise

  -- 39% of survey respondents have already deployed SIP trunking, and
     by 2010, it becomes the second most commonly deployed trunking type

-- Respondents are deploying SIP trunking widely across their
  organizations, and not just trialing at one or a few sites


Infonetics Research surveyed 92 North American organizations with 101 or more employees that use PBXs, phone systems including private branch exchanges and key telephone systems (KTS). Respondents have detailed knowledge of their organization's PBX trunking services and have influence over the planning and purchase decision-making process for PBX trunking services.
