EDB is one of the largest IT groups in the Nordic countries, with nearly 50 years of experience serving leading Nordic businesses. While Office Communications Server has been a great success at EDB, the company wanted to reduce costs further by expanding its voice deployment to individual users and to branch offices, and therefore upgraded to Lync Server 2010 while using AudioCodes Mediant Survivable Branch Appliances (SBA), enabling high-availability voice services for its branch offices.
To connect Lync Server to the public switched telephone network (PSTN), EDB uses a Session Initiation Protocol (SIP) trunk from Telenor. SIP trunking uses the Session Initiation Protocol and real-time transport protocol to pass network traffic from Lync Server over an IP connection to the PSTN using AudioCodes Mediant Survivable Branch Appliances (SBA). The SBA is based on cost-effective AudioCodes media gateways hosting the Microsoft Survivable Branch Appliance software package. The SBA provides network access and a PSTN connection, which maintains communications capabilities in the event of wide-area network (WAN) failure. By November 2010, EDB had deployed voice capabilities to 1,000 users.
