Configuring E911

Enhanced 911 (E911) is a feature first introduced in Lync Server 2010 and provides the caller’s telephone number and street address to a dispatcher automatically. This is an advantage over a very basic 911 service that requires the caller to provide an address where assistance is required.

Lync Server 2013 maintains a Location Information Service (LIS) database for an organization that associates specific gateways, subnets, and wireless SSIDs with physical location addresses. Lync Server 2013 supports E911 with support from a certified emergency services provider or through an ELIN certified media gateway. Emergency calls are routed through these options to the emergency services provider.
