If a client is located outside the network, or in an undefined subnet, the user can manually enter a location. But during an emergency call, the call will first be routed to a national/regional E9-1-1 Emergency Call Response Center (ECRC) dispatcher before being routed to a Public Safety Answering Point (PSAP). The ECRC will verbally query the caller for a location and then forward the call to the appropriate PSAP, based on the information provided.

Should users be prompted to enter a location when one is not automatically provided by the Location Information service?

For example, if a client is located in an undefined subnet, at home, in a hotel, or anywhere else outside the network, should the user be required to enter a location?

You can configure the Location Required setting in the location policy to define the client behavior. Setting this value to No means that the user will not be prompted for a location. Setting this value to Yes means that the user will be prompted for a location, but can dismiss the prompt. Setting this value to Disclaimer means that the user will be prompted for a location, and will be shown a disclaimer if they try to dismiss the prompt. In all cases, the user can continue to use the client as usual.

When a user manually enters a location, the location is mapped to the MAC address of the default gateway of the client’s network, and is stored in a per-user table located on the client. When the user returns to any previously stored location, the Lync client automatically sets itself to that location.

You can modify only the current location of your client, but you can also delete any location stored in the local user’s table.
