HP Survivable Branch Communication zl Module (SBM) powered by Microsoft Lync provides survivable branch services, such as external phone call capability, while sustaining internal peer-to-peer communications when the data center cannot be reached. SBM combines Microsoft Lync survivable branch application and software from HP, including a public switched telephone network (PSTN) to Voice over Internet Protocol (VoIP) gateway, a graphical user interface (GUI), management interfaces, and an application programming interface (API) to the switch itself, all of which are integrated on a module that fits in the chassis of HP E8200 zl and E5400 zl Switch series products.
