Enabling Users for E9-1-1

Topic Last Modified: 2012-06-08

During client registration, Microsoft Lync Server 2010 uses a location policy to configure the E9-1-1 properties for Enterprise Voice-enabled users. This policy contains the settings that define how E9-1-1 is implemented. For example, the location policy contains information such as the emergency dial string, and whether or not a user is required to manually enter a location if the Location Information service does not automatically provide one. For a complete definition of a location policy, see Defining the Location Policy.

Lync Server can assign a location policy to clients based on subnet, or to users based on a global, per-site, or per-user policy. To help decide how you will enable users, first answer the following questions.

• Do you plan to enable all users, or limit support to specific geographic areas of the enterprise?
  You can assign a location to all users in your enterprise by using a global location policy. However, by assigning a location policy to a Lync Server network site and then adding subnets to the site, you can limit E9-1-1 support to selected locations within the enterprise and specify E9-1-1 routing behavior on a per-site basis.

• Do you plan to enable individual users through a user policy?
  You can assign location policies directly to specific users or common area phone contact objects if you want to customize their E9-1-1 support.

• When clients roam outside the network or connect from an undefined subnet, should the clients still be enabled for E9-1-1?
  If users are assigned a global, site, or per-user location policy, they can be required to manually enter a location into the client if the client is not located within a defined subnet or no location has been found by the Location Information service. For details, see Defining the User Experience for Manually Acquiring a Location.
