SIP Trunking Adoption Rates Are Growing but Not Keeping Pace with VoIP


Although VoIP is a mature technology within corporate networks, a new report released by Sonus Networks Inc. and Webtorials states that SIP trunking is still in the early stages of adoption. The first annual SIP Trunking State-of-the-Market Report reveals that two-thirds of organizations make “significant” or “extensive” use of VoIP, while only one-third of organizations use SIP trunking to the same extent.

“SIP has been a relevant topic for almost a decade but we are just now seeing the adoption and implementation of the technology take off as the barriers to implementation disintegrate,” said Steve Taylor, Editor-in-Chief and Publisher for Webtorials. “The 2012 SIP Trunking State-of-the-Market Report identifies the growing trend of large enterprise SIP trunking deployments and outlines how the value that users seek goes beyond cost savings to enable new features and applications.”

The survey of 300 enterprise IT professionals also revealed:     

  • Cost savings is by far the most important driver for adopting SIP trunking. An overwhelming 73% of respondents stated that cost savings through SIP trunks and trunk consolidation is one of their biggest drivers, while 52% cited cost savings through the move to VoIP as one of their strongest drivers.
  • Those using SIP trunking see an average of 33% savings. The Sonus study wanted to get an accurate view of how much organizations can save through SIP trunking – as opposed to through VoIP or unified communications – so it asked only respondents who have either “significant” or “extensive” use of SIP trunking how much they have saved. While 28% of respondents did not know how much they have saved, the bulk of respondents (44%) have saved between 26% and 50%.
  • Lack of SIP trunking availability is preventing many organizations from adopting SIP trunking. According to the survey, 29% of respondents cited the “lack of availability of SIP trunking at all locations in my network” as their strongest deterrent to deploying SIP trunking, while 19% of respondents cited “lack of availability of SIP trunking from my service providers” as their biggest inhibitor.  Other key deterrents included costs and staff availability.
