Microsoft Lync (Microsoft Lync has been rebranded Skype for Business) is widely deployed yet most organizations are using Lync clients only for instant messaging, presence and directory access. Lync conversations are limited to other internal Lync users or with a few trusted external partners via Lync Federation.
To extend Lync’s value, GENBAND has developed solutions that enable users to securely make and receive calls from their Lync/Skype for Business client via the public telephone network, supplementing or replacing their existing PBX. Lync servers are connected to a communications service provider via Direct SIP trunks, secured by GENBAND's Session Border Controllers (SBC). GENBAND SBCs also provide SIP interworking to assure that services are delivered consistently across locations or between Lync and multiple PBX platforms.
Direct SIP trunks connected to Lync via GENBAND Session Border Controllers have been tested and qualified by Microsoft under its Unified Communications Open Interoperability Program.
