Survivable telephony in branch offices
Microsoft Lync Server 2010 (former CS14) is the first release which
will support remote site telephony even on WAN outages. Microsoft
has defined an appliance type of products which contains
all functions needed for telephony in a branch office – therefore
called “survivable branch appliance”.
OfficeMaster Survivable Branch Appliance is based on high quality
industrial grade server hardware (HP ProLiant) which runs
Windows Server 2008 R2 together with Microsoft branch office
components like Registrar and Mediation Server. All necessary
software is preinstalled and activation can be done through an
easy to use web UI by a local technician.
