Setting up an E911 Emergency Location using TAC

An E911 emergency location can be set up using the Microsoft Teams admin center.

To set up an E911 emergency location:
1. In the TAC, go to Locations and in the 'Emergency addresses' page, set a new location by clicking + Add.

2. Enter a name for the location, enable insert address manually, make sure that all data is filled in correctly and then click Save.

3. After the location has been set, click on the location and add a place (building, etc.). Make sure to maintain the hierarchy. Click Apply and verify the place has been set.

4. Enter the place you’ve set and define how to determine the emergency location. It can be determined by these values:
Port ID
Switch (Chassis) ID
BSSID (Wi-Fi access points)
Subnet
User predefined location (see below for more details).

The hierarchy of displaying a location is determined in the same order as above.

5. Enter a location defined by a specific port ID. Make sure to enter the port description correctly, as delivered from your switch (* the switch must allow LLDP transmit and receive and provide LLDP information).

6. Define a location defined by switch (Chassis) ID. The location can be the same since a room defined in the previous step can reflect a room in a building using the same switch).

7. Define a location by subnet. The location can be defined like switch ID (if in charge of several buildings, since it reflects a perimeter or an area).

8. Verify all settings have been implemented correctly, under the Networks & locations tab.

9. Verify all settings have been implemented correctly, under the Networks & locations tab.

After a location has been defined, make sure that:

AudioCodes' phone runs the latest firmware released.
AudioCodes' phone runs the Teams app issued June 2022 and later (U3-A and higher).
E911 information is displayed on the phone screen 30-120 minutes after the location is set (time estimated under laboratory conditions).
To trigger information to be shown before that time period, dial a 933-test call and check if the location has been accepted, displayed and vocalized by the announcer.
