Session Border Controller Week in Review

January 25, 2014

It was a busy week in the session border controller sector. Here are some of the major stories.

The Dell’Oro Group is predicting that spending in voice core key growth segments, LTE and IP multimedia subsystem (IMS) core will continue to increase over the next five years. This isn’t too surprising considering that Infonetics (News - Alert) Research predicted there would be 8 million VoLTE subscribers by the end of 2013 — before U.S. operators had even made the big VoLTE debut.


In another story, it was reported how a network upgrade is often one of those necessary evils. Everyone likes faster speeds and more bandwidth, but no one likes the downtime that often comes with it. After all, the old network needs to be taken offline so the new network can be put into place, a process that can take hours, days or even more. But that's not necessarily so, as illustrated by Network Norway's recent upgrades provided by Dialogic (News - Alert) and Gintel. In setting up the upgrade, Dialogic and Gintel brought in a Dialogic BorderNet 2020, a combination media gateway and session border controller (SBC), to help provide the level of service Network Norway was hoping for. Backing up the BorderNet 2020 was a Distributed Signaling Interface (DSI) Protocol Stack and a PowerMedia XMS software media service. This combination of equipment brought about an easier way to connect traffic by using session initiation protocol (SIP), and opened up the network to most any platform while still having sufficient robustness to establish connections for what was described as “tens of thousands of subscribers.”

In still another story, the communications test and measurement (CT&M) market was estimated to be at $3.75 billion in 2013 and is predicted to jump to $5.51 billion in 2018, according to a recent study from MarketsandMarkets. North America and the Asia-Pacific region are predicted to be the biggest markets when it comes to revenue, the study said. On the other hand, Europe and Latin America will see more market traction over the five years.

And SIP communications company Sonus Networks has made headlines again with the news that Calltrade Carrier Services, a Switzerland-based competitive operator, is using the Sonus SBC 5000 Series of session border controllers to support its wholesale VoIP service. The announcement comes less than a week after the news that Sonus began rolling out release 3.1 of the SBC 1000 and SBC 2000 session border controllers with enhancements meant to improve quality of experience management in Microsoft (News - Alert) Lync Enterprise Voice environments.
