Planning for Enterprise Voice Resiliency


Topic Last Modified: 2010-09-28

Voice resiliency refers to the ability of users to continue making and receiving calls if a central site that hosts Microsoft Lync Server 2010 becomes unavailable, whether through a wide area network (WAN) failure or another cause. If a central site fails, Enterprise Voice service must continue uninterrupted through seamless failover to a backup site. In the event of WAN failure, branch site calls must be redirected to a local PSTN gateway. This section discusses planning for voice resiliency in the event of central-site or WAN failure.
