The Dispatchable Locations menu item can be found per each Tenant under the Settings tab.
NOTE: In order to prevent calling 911, providers support a test number for this purpose. To test your 911 service, dial 933. This will take you to a recorded message that will read back to you the Caller ID that you are using and provide you with the E911 address that is setup for that DID.
If an Emergency Location is not set, the Communicator app will prompt to add one:
To add a location, select "Add Location" under Settings > Phone > Emergency Location.
The Online Self Care (OSC) window will appear. Select "Add Dispatchable Location" to add a new location.
