SIP Trunking Week in Review


By Ashok Bindra SIP Trunking Report Contributor



Enterprise session border controllers (E-SBCs) play an important role in enabling SIP trunking and all unified communications applications with Microsoft Lync. Ingate Systems’ E-SBC, the SIParator, is fully certified for use in Lync environments and meets or exceeds both the required and optional test parameters. That makes it one of the few E-SBCs that can support TLS and other security features offered by Microsoft Lync, wrote Ingate Systems’ president Steven Johnson in a TMCnet column this week. However, the article originally appeared in the April 2013 issue of Internet Telephony magazine.


According to Ingate’s president, Microsoft has a rigorous certification process for E-SBCs because it ensures seamless and reliable use of Lync applications. However, he cautioned that not all certified E-SBCs have been qualified to include the same security options. “Some only comply with the basic requirements,” wrote Johnson.

Also, this past week, TMCnet executive editor Erin Harrison highlighted the collaboration between GENBAND and Radisys. In this deal, GENBAND selected Radisys’ Software Media Resource Function (MRF) to provide the IP media processing for its EXPERiUS application server and CONTiNUUM call session controllers.

The report indicates that this collaboration will enable GENBAND to extend its reach to markets such as SIP trunking, unified communications, HD voice and voice and video over LTE. The report quotes GENBAND’s president BG Kumar as saying, “The full integration of the Radisys Software MRF with our EXPERiUS application server and CONTiNUUM call session controllers allows GENBAND to continually enhance and focus resources on our market-leading application and session control solutions programs, resulting in accelerated time to market.”

In other news, Canada's all-business communications provider Allstream announced an expansion of its SIP trunking service that will enable it to reach an additional 10,000 mid-size and large enterprises across the country. This means that more companies in more cities can benefit from being able to run data and voice traffic over a single IP backbone, eliminating the need for separate voice and data networks, said Allstream.

By converging voice and data, customers will see costs savings of up to 40 percent, according to Allstream’s vice president of marketing Jim DeMerlis. "We look forward to bringing these cost savings, as well as productivity improvements associated with SIP Trunking to more Canadian businesses," asserted DeMerlis.

Meanwhile, TMCnet contributor Anil Sharma reported that Cox Business launched a cloud-based voice system, VoiceManager IP Centrex, that is designed to fuel productivity and maintain financial controls in one reliable communications platform for small businesses. It provides an affordable, predictable voice solution that makes forecasting and expense management simple.
