Configure Enhanced 9-1-1 in Lync Server 2013


Topic Last Modified: 2013-02-24

Enhanced 9-1-1 (E9-1-1) is an emergency notification feature that associates the calling party’s telephone number with a civic or a street address. Using this information, the Public Safety Answering Point (PSAP) can immediately dispatch emergency services to the caller in distress.

To support E9-1-1, Lync Server 2013 must be able to correctly associate a location with a client and to make sure that this information is used to route the emergency call to the nearest PSAP.

For details about planning for an E9-1-1 deployment, see Planning for emergency services (E9-1-1) in Lync Server 2013.


Lync Server 2013 only supports E9-1-1 within the United States. To deploy E9-1-1, you need to configure a SIP connection to a qualified E9-1-1 service provider, or deploy an emergency location identification number (ELIN) gateway to a public switched telephone (PSTN)-based E9-1-1 service provider. For details, see Enhanced 9-1-1 (E9-1-1) and Mediation Server in Lync Server 2013. For details about configuring trunk connections, see Configure a trunk with media bypass in Lync Server 2013.
