GENBAND announces that the SIP Business Trunking softswitch solution offered on its market-leading GENBAND C20 Converged Softswitch has achieved interoperability qualification with Microsoft Office Communications Server 2007 R2. Additionally, GENBAND announced that its C20 softswitch is an integral component of the Swisscom SIP Trunking Solution which was recently certified for use with the Microsoft Lync Server 2010. Swisscom, Switzerland’s leading telecoms provider, announced last month that Microsoft certification of its VoIP Gate service enables the Company to offer its corporate customers a complete IP-based communications solution that is both innovative and reliable.

Microsoft Unified Communications Open Interoperability Program ensures that customers have seamless experiences with setup, support and use of qualified telephony infrastructure and services with Microsoft Corp.’s unified communications software. With more than 650,000 ports deployed globally, GENBAND’s solutions for SIP trunking have been tested with the majority of PBX solutions available in the business market.

GENBAND’s solution for SIP Business Trunking allows service providers to deliver flexible and low-cost IP-based communications between an enterprise PBX and the public network. With the GENBAND solution, service providers are able to support multiple voice sessions that are managed under a single account for billing, maintenance and service assurance. In addition, by eliminating the need for separate voice and data connections, SIP Business Trunking helps reduce costs for enterprise users and can lay the groundwork to offer subscribers a variety of real-time applications including Unified Communications, Instant Messaging, Network Presence, Mobility, Messaging and Desktop Integration.
