The location profile defines the default set of normalization rules that are applied to phone numbers dialed by users in this pool. Normalized phone numbers are used to perform “reverse number lookup,” which is the process of finding a recipient’s Session Initiation Protocol (SIP) Uniform Resource Identifier (URI) from their phone number. If this lookup fails, a call is routed according to routing rules configured at the global level for the forest.

The location profile you select as the default should include all phone numbers to which calls can be routed for this pool. The list contains all location profiles defined for your organization. To define a location profile, use the Location Profile tab of Voice Properties for the forest node.

Communicator Phone Edition devices can be locked for security purposes. If you choose to enforce the phone lock, it is enforced only in the pool for which it is configured.

You can configure advanced options to specify quality of service and SIP security settings for the pool's Enterprise Voice support.
