Webtorials: SIP equipment license issues; UC's ongoing operational costs

Today, we'd like to take note of two issues covered by recent analysis provided at Webtorials. The first, a tech note titled "Ten SIP Trunk Equipment License Issues That Can Ruin Your Day (or Month)," was penned by our longtime colleague Gary Audin at Delphi. The second study, written at Nemertes, discusses how "Operational Costs Drive Stark Differences in First-Year Telephony [and] UC."

In his note, Audin looks at how SIP equipment license limitations can affect the costs associated with an IP PBX and Session Border Controller (SBC). Beginning with a definition of a SIP license, the analysis looks at how these licenses can be structured and calculated -- offering the reader insights on how to anticipate and manage associated costs and technical limitations.

The second piece by Nemertes points out that since fewer than 20% of companies have fully deployed VoIP or unified communications, we can expect to continue seeing new and expanded deployments for many years to come -- with variability in the prices and business models.

The research suggests that most vendors are competitive when it comes to capital costs and that basic implementation costs do not vary significantly, but ongoing operational costs do. These costs vary based on rollout size, vendor and product, meaning there is not one vendor that is the most cost‐effective for every rollout and every size.

For example, NEC and ShoreTel generally are the low-cost providers as measured by first year costs, but Avaya and ShoreTel have the lowest operational costs -- meaning subsequent years should be most affordable with them. The study suggests that while Microsoft provides a compelling value proposition Lync as a collaboration product, ongoing operational costs -- particularly when used for voice -- are significantly higher than competitors.
