Enhanced 911 is a feature that was not possible in earlier product versions of Lync Server. Enhanced 911 provides the caller’s telephone number and street address to a dispatcher automatically. This is an advantage over traditional 911 service that requires the caller to provide an address where assistance is required.
Lync Server 2010 can maintain a location database for an organization that associates specific gateways, subnets, and wireless SSIDs with physical location addresses. Lync Server 2010 supports E-911 with support from a certified emergency services provider. Emergency calls are routed through a SIP trunk to the emergency services provider.
