Explanation:
To ensure that when users dial emergency numbers, the call is routed based on the user's current location, you need to enable the external location lookup mode in Teams. This mode allows Teams to use the location services of the device's operating system to suggest an emergency address for the user. The user can then confirm, edit, or enter a new address, which will be used to route the emergency call to the appropriate Public Safety Answering Point (PSAP). Here are the steps to follow:
Sign in to the Teams admin center with your admin credentials.
Go to Voice > Emergency policies.
Select Add.
Enter a name for the emergency calling policy, for example, "E911WFH".
Turn on External location lookup mode.
Select Apply to create the policy.
To assign the policy to the users who need it, go to Users on the left menu and select the users that you want to apply the policy to. You can use the filters or the search box to find them.
On the right pane, under Policies, select Edit next to Emergency calling policy.
Choose the policy that you created from the drop-down list and click Apply.
