E911 Setup Guide

Enabling e911 Emergency Calling in Evo Voice

By default, SIP extensions in Evo Voice do not support emergency (911) calling. Enabling e911 links an incoming phone number with a SIP user, ensuring that the associated address is sent to emergency services during a 911 call.

This guide outlines the steps required to enable and test e911 functionality.

Overview of Steps

1. Create an Emergency Address

2. Enable Emergency Dialing on the Incoming Phone Number

3. Associate the SIP User with the Emergency Phone Number

4. Update the Phone's SIP Domain Setting

5. Test the Configuration

Step 1: Create an Emergency Address

1. Navigate to the Addresses Section

   • Go to System > Settings > Addresses.

   • Expand the Addresses section.

2. Add a New Address

   • Click New Address.

   • Enter:

     • Friendly Name (e.g., "Business Office").

     • Homeowner/Business Name.

     • Complete Address Fields.

     • Check the Emergency Address box.

3. Address Validation

   • If you receive an error message, ensure the fields match the required format and re-save.

Step 2: Enable Emergency Dialing on an Incoming Phone Number

1. Locate the Phone Number

   • Go to Endpoints and search for the number to enable e911 on.

   • Ensure this number is assigned to a Flow (e.g., a "Dial User" flow).

2. Enable Emergency Calling

   • Edit the number and go to the Emergency Tab.

   • Check the Enable Emergency Calling box.

   • Select the previously created emergency address.

3. Recommended Flow Configuration

   • Use a Dial User flow so emergency call-back numbers ring directly to the SIP user.

Step 3: Associate the SIP User with the Emergency Phone Number

1. Edit the SIP User

   • In Endpoints, locate and select the SIP user.

   • Navigate to the SIP Tab.

2. Assign Emergency Number

   • In the Emergency Number field, search for and select the configured phone number.

   • Save the changes.

3. Update the SIP Domain

   • After assigning the emergency number, the SIP domain will change.

   • Update the domain settings on the SIP device to match the new configuration.

Step 4: Test the Configuration

1. Wait for Changes to Propagate

   • Allow up to 10 minutes for the SIP handset to sync.

2. Test Emergency Calling

   • Dial 933: A recorded message will confirm the caller ID and associated emergency address.

   • Optionally, dial 911: Inform the operator that this is a test call and request verification of the address.

     • Note: Some areas require scheduling test calls. Check local regulations.

3. If Testing Fails

   • Contact your Evo Voice support representative for assistance.

Important Notes

• Multiple phone numbers can share the same emergency address.

• Ensure the address is accurate and validated during setup.

• Misconfigured settings can result in failed emergency calls, so test thoroughly.

By following these steps, you can ensure e911 functionality is correctly set up for SIP devices in Evo Voice.
