This Infonetics chart should be enough to convince anybody about SIP trunking

Nobody wants to be the one out of four companies that sticks with expensive, inefficient phone service, do they?

In SIP Trunking and eSBC Strategies: North American Enterprise Survey (purchase required), a report released just last week from Campbell, Calif.-based Infonetics Research, analyst Diane Myers predicts that 78 percent of enterprises will have deployed SIP trunking within the next two years, which amounts to 3/4 of firms. This chart shows the primary business drivers:

What makes centralized trunking so attractive, according to Avaya and others, is that it helps organizations make use of otherwise idle bandwidth, reallocating it for other uses and applications.

“The main barriers to deploying SIP trunking are not directly related to the service itself, but more about respondents’ existing situations,” Myers writes, adding that T1 lines will be slow to disappear. “Many are satisfied with their existing voice services, their service contracts aren’t up for renewal, or SIP trunks aren’t offered at the desired location.”

Of course, a lot can change by 2016. Infonetics’ study is proof of that.
