Sonus Networks, Inc. (Nasdaq: SONS), a global leader in SIP communications, today announced that the Sonus SBC 1000 and Sonus SBC 2000 are Microsoft Lync 2013 qualified for session border controller (SBC) and survivable branch appliance (SBA) deployments. A Microsoft Gold Communications Partner, Sonus helps enterprises optimize Microsoft Lync voice deployments by securing Session Initiation Protocol (SIP) trunking services at the network border and providing a more seamless flow of SIP-based multi-vendor media for Unified Communications (UC) deployments. Access to UC applications such as instant messaging (IM), collaboration, conferencing and voice empowers enterprises to communicate in the most efficient and cost-effective ways – whenever and wherever. The Sonus portfolio provides the industry’s only end-to-end SBC solution delivering SIP-enabled applications from the enterprise headquarters to the branch office. SBCs are the critical access technology to enable customers to unify disparate UC architectures across an enterprise. According to the January 2013 Webtorials study, “ Enterprises Place 2013 Unified Communications Bets: How Many Horses in This Race?” there is considerable enterprise awareness and interest in Microsoft Lync as a platform for UC and enterprise voice. A full 58 percent of those surveyed already plan to deploy Microsoft for IM and presence, and it appears to have the inside track with many buyers when it comes to more advanced UC functions like Web meetings, desktop sharing and advanced directory services. A recent Nemertes Research report, “ Microsoft Lync Reality Check,” indicated that most companies are implementing a gradual transition strategy to Microsoft Lync voice, starting small and either augmenting existing telephony systems or gradually migrating those groups most well suited to a softphone-centric working model. For this reason, it is critical that different networks and different network elements from a variety of vendors can communicate effectively with one another. Sonus SBCs are designed and tested to provide interoperability with legacy equipment (TDM, H.323), multiple SIP vendors and standards, application providers and international standards. With the industry’s broadest portfolio of Microsoft Lync qualified SBCs, Sonus gives enterprises and service providers more choices to communicate more effectively, more efficiently and more intelligently. The award winning SBC 1000 and SBC 2000 are designed to help medium sized businesses and branch offices safely and cost-effectively embrace new SIP-based communications. These Sonus SBCs deliver built-in media transcoding, network security (such as encryption, authentication and denial of service (DoS) protection), robust SIP interworking, intelligent call routing and multi-vendor interoperability.
