Effective planning for Enhanced 9-1-1 requires that you take into account the following:

Deployment Prerequisites for E9-1-1

Before you deploy E9-1-1, you must already have deployed your Microsoft Communications Server 2010 internal servers, including either an Enterprise pool or a Standard Edition server, and Communications Server 2010 clients. In addition, an E9-1-1 deployment requires A SIP connection to a certified Emergency Service Provider. Communications Server only supports using E9-1-1 with certified Emergency Services Providers located inside of the United States.

The following table provides an overview of the E9-1-1 deployment process. For details about deployment steps, see Configure Enhanced 9-1-1 in the deployment documentation.
