Beyond Convergence: An Interview with Forrester’s Brownlee Thomas on SIP Trunking

SIP trunking is rapidly becoming a key enabler of advanced unified communications capabilities for today’s complex network infrastructures.

SIP trunking is the next step toward full voice and data convergence, but it’s more than just another VOIP technology. Brownlee Thomas, a Principal Analyst for Forrester Research, recently spoke to expertIP following a live SIP trunking panel event in Edmonton.

“What’s different about SIP trunking,” Thomas said, “is its readiness for unified communications. All of those advanced UC applications that we’re looking at now require SIP to integrate. SIP gives you that environment and the readiness for full unified communications.”

Thomas also spoke about the lingering misconceptions about SIP trunking—namely that it’s too expensive to implement in this challenging economy—and some of the factors to consider when preparing your network for SIP migration.

“First you have to assess your network and bandwidth requirements,” Thomas said on the topic of SIP trunking migration. “Whereas we had separate access for voice and data and Internet for a typical MPLS and WAN environment, now we’re consolidating those connections onto the IP transport.”

There are other factors to consider, including finding a provider who can deliver a guaranteed quality of service on voice traffic, but SIP trunking’s cost savings and efficiency gains are worth the planning and preparation.
