Enhanced 9-1-1 (E9-1-1) is an emergency notification system that associates the calling party’s telephone number with a physical address. By using this physical address or location information, a Public Safety Answering Point (PSAP) can immediately dispatch emergency services to the caller in distress. Traditional 9-1-1 service associates a telephone number only with its billing address, which may not be the location where the emergency call originates. For example, an organization may occupy a large building or a series of buildings). By deploying an E9-1-1 system, an organization can provide the exact location of the emergency call, such as the building, floor, and conference room, to the appropriate PSAP.

In order to support E9-1-1 as part of a Microsoft Lync Server 2010 Enterprise Voice deployment, you must obtain E9-1-1 routing service from a certified emergency services provider.

Lync Server 2010 currently supports E9-1-1 only in the United States.
