E9-1-1 Support

Topic Last Modified: 2012-06-11

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’s telephone number with a civic (that is, street) address. E9-1-1 support is available only in the United States.

You can support E9-1-1 as part of a Lync Server deployment by using a SIP trunk connection to an E9-1-1 routing service from a qualified E9-1-1 service provider, or by using and Emergency Location Identification Number (ELIN) gateway that connects to your public switched telephone network (PSTN) carrier. The qualified or PSTN E9-1-1 service 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.
