All Features of a Traditional PBX Now Available on SIP PBXs:

SipTrunkingReport Editor

Part of what’s driving the extremely high adoption rate of SIP technology among enterprises is their attempt to take advantage of the centralization and consolidation benefits of VoIP, an official with a Cary, N.C.-based business communications provider told TMCnet.

According to Sean Rivers, director of product marketing at, large companies seeking to save money are centralizing their PBX infrastructures to a few hardened facilities while scaling back the services delivered to the remote offices is the best way to accomplish this goal.
“VoIP is the only way to make this happen,” Rivers told TMCnet in an interview, printed in full below.
Rivers is speaking during a session at ITEXPO West 2009, to be held Sept. 1 to 3 in Los Angeles, titled “Introduction to SIP Trunking,” which will include a live demonstration of panel members setting up a secure SIP trunk in 20 minutes or less.
For Rivers, adoption numbers in the SIP trunking segment are only expected to grow.
“We are not quite sure when market equilibrium will set in and balance out the growth, but for now are growing rapidly,” Rivers told TMCnet. “This customer demand is mostly generated by customers looking to save money.”
Our full exchange follows.
TMCnet: Certainly one area of SIP-based technology that’s widely discussed in the industry is the SIP Forum’s “SIPconnect” initiative, which promotes an industry-wide, standards-based approach to direct IP peering between SIP-enabled IP-PBXs and VoIP service provider networks. Give us your perspective on the issue. What does this effort mean for you?
Sean Rivers (pictured left): One of the chief issues facing the SIP phone service industry is interoperability. We will not be able to keep customers happy if every call and feature does not work as expected. Before the SIPconnect initiative we were never sure if all phone system features would work are we require, now we are able to begin the interoperation testing from a much better position. This has been an incredible help to us.
TMCnet: Talk to us about what you’re seeing in the SIP market? From your perspective, what exactly is driving the take-rate in SIP?
SR: We see a few reasons companies are adopting SIP. One of those reasons is simply a cost savings over traditional phone services. The most surprising we have seen recently is in large and very large enterprise customers trying to take advantage of the centralization and consolidation benefits of VoIP. Large companies want to save money in a very meaningful way and centralizing their PBX infrastructure to a few hardened facilities while scaling back the services delivered to the remote offices is the best way to accomplish this goal. VoIP is the only way to make this happen.
TMCnet: What do you think will drive the adoption of SIP in the future? What kinds of things are people looking for?
SR: We definitely see and expect the adoption numbers to continue to grow. We are not quite sure when market equilibrium will set in and balance out the growth, but for now are growing rapidly. This customer demand is mostly generated by customers looking to save money.
TMCnet: Following up on that, talk to us about how much of the feature set of a traditional PBX is now available on a SIP PBX?
SR: I used to say that it is all possible on a SIP PBX, but now I can say with comfort that it is all available. I would so far as too say that a SIP PBX has more features than a non-SIP PBX.
TMCnet: What is the timetable, in your view, for having all of the features available on a TDM PBX on a SIP PBX?
SR: They are all there today.
TMCnet: Talk to us about your involvement and interest in ITEXPO. What kind of information are you providing?
SR: I have been involved with the ITEXPO for the last three years and hope provided my perspective as a VoIP service provider to others in our industry. ITEXPO is also a great place to meet with some of our industries smartest people. I pick a lot of brains and hope that some of my insights help others.
