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

In order to support E9-1-1, Communications Server 2010 must be able to correctly associate a location with a client, and then to ensure that this information is used to route the emergency call to the nearest PSAP.

For more information about deploying E9-1-1, see Emergency Services (E9-1-1).

Communications Server only supports using E9-1-1 with certified Emergency Services Providers located inside of the United States. Before deploying E9-1-1, you will need to configure an SIP connection to a certified Emergency Service Provider. For more information, see Enhanced 9-1-1 (E9-1-1) and Mediation Server. For more information about configuring trunk connections, see Configure Media Bypass on a Trunk.
