Remote Teleworker and Off-Premises User—E911

Remote Teleworker and Off-Premises User—E911 Overview

Cisco Emergency Responder can be configured to provide E911 support to remote teleworker and off-premises users. These users, when registering over Virtual Private Network (VPN) or Mobile Remote Agent, can update their location through the phone display or through Cisco Emergency Responders Off-premises User Page. The Enterprise requires an arrangement with a National Emergency Service Provider to perform location updates, Master Street Address Guide (MSAG) address validation, and call completion.

Currently, Cisco Emergency Responder supports integrations with Intrado as National Emergency Service Providers.

Cisco Unified Communications Manager (Unified Communications Manager) requires users with off-premises phones to set their current location before allowing any outbound call from the phone. Users that have an off-premises phone rely on Unified Communications Manager to route their emergency calls to a National Emergency Service Provider to deliver the emergency call to the appropriate Public Service Answering Point (PSAP) along with the current address.

A legal disclaimer notice is displayed on any phone device that is dynamically identified as an off-premises device (that is, connected remotely to the customer network). The disclaimer advises the users that their administrator has identified their device as outside the customer network and the user must select their current location before being able to place outbound calls. Users can confirm their current location or select another previously stored location from their device display.

If the user's current location has not been previously defined, the user is directed to the Cisco Emergency Responder Off-Premises User web page to create a new location. After the new location has been defined and the address has been validated in the MSAG, emergency calls placed from off-premises phones will then be completed through the National Provider.


Note


Remote Teleworker or Off-premises user can have up to 8 preconfigured locations.

Note


Extension Mobility is not supported for off-premises users.

Configure Remote Teleworker Emergency Calling For Off-Premises Locations

Add New Location

Before a user can associate a location to their phone or device, the user must first enter a location into Emergency Responder. All locations defined in Emergency Responder are user-specific. Each user must add their own locations. When a user has multiple locations, each location must have a unique name to identify that unique location.

Procedure


Step 1

Log in to the Cisco Emergency Responder Off-Premises User page at https://<CER_FQDN>/ofpuser using the end user credentials.

Note

 
Emergency Responder Off-Premises User page does not support SSO logins.

Step 2

From the Cisco Emergency Responder Off-Premises User page, select Locations and click Add New Locations.

Enter a valid address. Use this location name to identify this address when you associate your phone with this address.

Step 3

Click Validate to verify the address with your National Provider.

Step 4

If the address validation fails, the user must correct the address before saving the location.

Step 5

Click Save to save the location information in Emergency Responder.

Note

 
Saving the location does not immediately update the National Provider, but stores the location information in Emergency Responder. When a user selects the location from the device, the stored address information is sent to the National Provider to update the address for the user’s E.164 number.

Associate Your Location to Your Phone

After a user defines a location in Emergency Responder, the user should associate and verify that the device is associated to the desired location.

Procedure


Step 1

From the Cisco Emergency Responder Off-Premises User page, choose Phones.

Step 2

To associate a location to a phone, click the corresponding Assign link.

Step 3

In the Associate Location page, select the desired location from the Select New Location drop-down list. The new location becomes active when you click the Associate Location button.

The Status field show displays that the “Location Association Is Successful.” This indicates that the address is valid and has been updated with the National Provider.

Step 4

Once the location is associated, the device on the Phones page should display the device status as Off Premises and the Associated Location should match the one that was selected. Additionally, ensure that the Direct Inward Dial (DID) is a properly formatted 10-digit NANP number.


Verify the Remote Teleworker Off-Premises Locations in Emergency Responder


Note


If the remote or off-premises user chooses not to update their current location, the Disclaimer prompts the user to acknowledge that calls may be restricted until the location is updated. 911 calls will not work until the user decides to associate their device to the desired location.

As the System Administrator, you can configure to select and mandate location update so that the device user has to acknowledge the disclaimer and provide current location information before the device is enabled for normal use. (From Cisco Unified CM Administration, choose System > E911 Messages to configure the mandatory location update disclaimer message.)


Procedure


Step 1

Reset the phone or device.

After the phone has rebooted and after 2-5 seconds after registering, the device should display the Remote Teleworker legal notification. At this point, the remote teleworker location selection process should start.

Step 2

Ensure that the following legal disclaimer message appears on the phone.

Step 3

Click Next.

You will get the details of all the locations added through Cisco Emergency Responder Off-premises URL.

Step 4

Using the toggle buttons on the phone or device, choose a location and press the Select button.

A few seconds later, the phones user interface should indicate the successful settings of the off-premises user’s location.


What to do next

Administrators should instruct the users on how to validate the accuracy of the E911 address based on the user-defined setting. This process should follow the company’s procedure for emergency address validation. When a user dials 911 as per the company process for validating the emergency dispatch address, the call should be routed to public-safety answering point (PSAP) using the off-premises ERL and the address reported by the PSAP should be the address currently assigned to the device through the Cisco Emergency Responder Off-Premises User Page.

Configuring Mobile and Remote Access Connected Devices

Configuring devices connected over the Mobile and Remote Access Edge (Cisco Expressway-E/C) will occur in the same way as the VPN connected phones. The IP Subnet used to identify Mobile and Remote Access clients will be the Expressway-C’s IP Address. All phones or devices registered to Unified Communications Manager using Mobile and Remote Access will have the same IP Address as the Unified CM.

The configuration procedures for Mobile and Remote Access clients are the same as for VPN clients except that the Mobile and Remote Access setup requires one additional configuration step on the Expressway-C to work. In order to allow the HTTP requests from the phones to the E911Proxy service to obtain the XSI messages, the external Cisco Expressway server must have an explicit HTTP service mapping. This mapping is required to map the external request to an internal resource.

The following configuration must be set up in the Cisco Expressway:

Procedure


Step 1

From the Cisco TelePresence Video Communication Server Control, navigate to Configuration > Unified Communications > HTTP allow list > Editable inbound rules.

Step 2

Enter a description.

Step 3

Enter the URL to reach the E911Proxy service. The URL should be https://cucmfqdn:8080/e911proxy .

Step 4

Enter the Allowed Methods and Match type.



Note


Because E911Proxy HTTP requests are node-specific, the Expressway administrator must add the ‘E911Proxy’ service for all call processing nodes in the cluster. Any node that has phone registrations must have an Expressway-C entry to allow the XSI messages to be retrieved to complete the remote teleworker location selection process.
