Microsoft Lync Server 2010 uses a Location Policy to enable Lync Server 2010 clients for E9-1-1 during client registration. A Location Policy contains the settings that define how E9-1-1 will be 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 Server does not automatically provide one. For a complete definition of a Location Policy, see Location Policy Definition.

Lync Server can assign a Location Policy to clients by a subnet or directly to the user through a user policy. To help decide how you will enable users, you should first answer the following questions.

Do you plan on enabling all users, or limiting support to specific geographic areas of the enterprise?

You can enable all users by using a global Location Policy. By assigning a Location Policy to a network site, and then adding subnets to the site, you can limit E9-1-1 support to selected locations within the enterprise. Note that if you use the global location policy to enable users, users will always be enabled for E9-1-1 outside the enterprise.

Do you plan on enabling individual users through a user policy?

You can assign Location Policies directly to users if you would like to customize their E9-1-1 support.

When clients roam outside the network, or are located in a subnet not defined in the network site, should the clients still be enabled for E9-1-1?

Users are required to manually enter a location into the client if the client is not located within a defined subnet. For details, see Defining the User Experience for Manually Acquiring a Location.
