Microsoft Lync Server 2010 communications software supports Enhanced 9-1-1 (E9-1-1) as part of an enterprise deployment. E9-1-1 is an emergency notification feature that associates the calling party‚Äôs telephone number with a civic or street address. E9-1-1 support is only available in the United States.

In order to support E9-1-1 as part of a Lync Server deployment, you must obtain E9-1-1 routing service from a certified emergency services provider. The emergency services provider routes emergency calls originating from Lync Server to the correct Public Safety Answering Point (PSAP) based on the location information contained within the call. For details about E9-1-1 support, see Emergency Services (E9-1-1) in the Planning documentation.
