Reaching the SIPping Point

on April 17, 2013 by Dan Jacobson

Well, it looks like we're getting close to another one of those "tipping points," when usage of the new-and-better technology surpasses the legacy technology. From then on, it's just a matter of time before the new crowds out the old.

That tipping point for SIP Trunking looks to be somewhere in 2015. At least that's what the respected analyst firm Infonetics Research predicts, based on a recent survey and report. The firm made public some of the highlights from the report, which focuses on enterprise plans for both SIP Trunking and session border controllers. More...


A Front-Line View of Unified Communications

on November 30, 2011 by Dan Jacobson

There are some interesting findings in a new “Benchmark Report” on Unified Communications from Nemertes Research, especially relative to return on investment and mobility. The report (registration required) is based on interviews with 240 IT leaders, so this is front-line intelligence. More...


The Reasons Behind SIP Trunking Reluctance

on November 03, 2011 by Dan Jacobson

If SIP Trunking looks so good on paper – and it does – as you run the numbers on it for cost savings and productivity gains, why do many enterprises seem so half-hearted about it?

Sorell Slaymaker, writing at NoJitter, has some thoughts on that, with some interesting insight into why it is that, as he says, some 70 percent of organizations have SIP trunks in their network environment, but only five percent have fully migrated. More...


A Useful SIP Trunking Survey

on September 29, 2011 by Dan Jacobson

Polls can be useful, or they can be irritating. The useful polls help us determine trends that really have an impact on how we conduct business or conduct our lives. The irritating polls are those that ask people to offer opinions about things that they simply don’t have sufficient information to judge. More...


Two Views on SIP Trunking

on August 29, 2011 by Dan Jacobson

We love a good debate. Since you can’t get them when it comes to political candidates anymore (everybody’s too worried about each answer containing a good sound bite and one of two or three talking points), a good place to turn might be NoJitter.

There’s an interesting back-and-forth exchange between consultant Marty Parker and NoJitter Editor Eric Krapf about SIP Trunking. It will be clear which of the two of them we side with, but both have good points to make. Marty’s side is here, and Eric’s is here. More...


SIP Trunking’s ‘Second Wave’

on August 08, 2011 by Dan Jacobson

While enterprises have welcomed the cost savings that SIP Trunking enables immediately, there is an entire range of benefits waiting in the wings thanks to the technology, according to a new white paper from the analysts at Ovum.

This “second wave,” as Ovum calls it, offers the promise of integration, centralization, and deployment of UC in enterprise environments. We’ve talked many times here about SIP Trunking as the foundation for UC, and it’s always good to see this kind of validation of our position. More...


The Role of a Session Border Controller

on June 07, 2011 by Dan Jacobson

For a quick read on the subject of how session border controllers (SBCs) fit into the SIP Trunking ecosystem, we’d recommend you jump over to a recent post at NoJitter.com. More...


Doing SIP Trunking Bandwidth Math

on May 26, 2011 by Dan Jacobson

We talked in my last post about what IT staffs, and voice folks as well for that matter, have to take into consideration when it comes to determining trunk bandwidth needs, how to prioritize voice and video, and understanding the roles that different pieces of equipment play. More...


SIP Trunking Attitude Adjustments

on May 16, 2011 by Dan Jacobson

Often when we talk about SIP Trunking here, we focus on the mechanics of the technology and the benefits it brings. But implementing SIP Trunking does mean some real changes for the front-line people who make voice and data communications work in the enterprise. More...


SIP Trunking: Starting Small … and Mid-Sized

on December 16, 2010 by Dan Jacobson

In the same way that social media and smartphones have been driven by consumers, SIP Trunking may end up driven by small to medium businesses. That’s the implication of a Heavy Reading report, which Sean Buckley of Fierce Telecom wrote about earlier this year. More...
