Setting up emergency services with Intrado

Intrado Inc. is the largest E911 service provider operating throughout the US and Canada.

Once an end user connects with Intrado, fills in their address information in PortaBilling (on the account self-care interface or via the online web signup form) and submits it to enable E911 services on their account, the information is sent to Intrado using the API. Then the user’s location information is checked and verified in Intrado’s database. Users must have valid US or Canadian numbers for this to function properly. Once that verification is successful, PortaBilling receives notification of it and the E911 services are enabled for the user’s account.

This connection is handled by the special Porta::E911:Intrado plugin. The sections below demonstrate the steps required to set up and configure E911 service provisioning using Intrado.

Use this checklist to check off the operations you have completed while performing the system setup according to the instructions in this chapter. Please be sure to perform all of the operations in the order designated (all of the boxes should be checked), otherwise, the service will not work.

The checklist below assumes that you have already configured the basic SIP service according to the instructions provided in the Basic Residential VoIP Service handbook.

Before setting up Intrado E911 services in PortaBilling, it is necessary to obtain a National Emergency Number Association Company Identifier (NENA ID). This is a three- to five-character code that allows 911 centers to quickly identify the telephone company or access infrastructure provider responsible for a particular telephone number.

The NENA ID is obtained by filling in an online Company Identifier Data Base Update Form and submitting it through the NENA website (http://www.nena.org).

You will need to obtain a digital certificate from Intrado.

Intrado’s Validation and Update Interface (VUI) uses this certificate to verify that the user location information provided is real.

1. Sign a contract with Intrado Inc. (http://www.intrado.com/). You will receive a VUI account ID, username, enrollment passphrase and confirmation number from Intrado’s Product Support. You will also be provided with a URL link to Intrado’s VUI interface. This link will be used to receive user information validation requests.
2. Download your digital certificate following Intrado’s guidelines.
   The digital certificate has an activation date. It will not be activated prior to this date.

It is necessary to upload the VUI certificate to the PortaSwitch web server.

1. Check that the certificate is decrypted. Otherwise, decrypt it.
2. Log in to your web server using ssh.
3. Copy the certificate using the following command:

   sudo scp user@remote.host:/full_path_to_certificate/ITSP_VUI.p12
   /home/porta-admin/
   
   user@remote.host password:
   
   ITSP_VUI.p12 100% 0 0.0KB/s 00:00

1. Clone the active configuration.

   

2. Select the E911 group and specify the following information:
   • EmergencyPlugin – select Porta::E911::Intrado.

     

3. Select the Intrado group and specify the following information acquired from Intrado:
   • VUI_ACCOUNT – type the VUI account ID provided by Intrado.
   • VUI_CPF – type your NENA ID here.
   • VUI_PKCS12 – type the full local path to the digital certificate provided by Intrado.
   • VUI_URL – type the URL provided by Intrado.
4. Click the Save button and then the  Verify button.
5. Verify the new configuration and click the  Check/Apply button. Note that the Apache service will need to be restarted, so consider applying the configuration during off-peak time.
