Calling SIP Trunking a “bright spot” amid “muted” enterprise spending, the always perceptive Matthias Machowinski, Directing Analyst at the widely respected firm Infonetics Research, wrote about the technology in a recent Connected Planet post.
As he explains, referencing three studies the firm has done, there is strong evidence of the growth of the SIP Trunking market. Those studies came at the topic from different perspectives, including a survey of end user companies regarding their plans for SIP Trunking technologies.
“The consistent theme is that there is increased interest in and deployments of SIP trunking services,” Machowinski says. He points to the fact that the number of active SIP trunks provided by carriers worldwide more than doubled last year, that the enterprise session border controller market grew 53 percent in the same period, and that more than half of the end user survey respondents have plans to use SIP trunks by 2012.
We agree completely with the drivers that Machowinski identifies as behind the growth of SIP Trunking, such as cost savings over traditional telco circuits, thanks to the robust scalability of SIP Trunking. Another reason: simplification, the centralization of trunking services and the streamlining of the converged network. He also points to applications such as end-to-end VoIP transport, high-definition voice, and multimedia communication sessions as attractive aspects of SIP Trunking.
What seems to be holding SIP Trunking back for enterprises, Machowsinki notes – and we see this at Sprint in our interaction with these companies – is that they are reluctant to make changes to their trunking services until it’s time for a broader upgrade to their voice infrastructure. That is tied at least in part to the sluggishness of the economy, and once that turns around, the pace of growth should accelerate.
