You must create a reverse proxy service to download a file or firmware for endpoints on an Avaya SBC device.
You can configure multiple reverse proxy services using the same IP address if the listen ports used are different. If the same port needs to be reused, then configure a different IP address through Network Management.
  1. Log in to the EMS web interface with administrator credentials.
  2. From the Device menu, click the SBC name to administer.
  3. Navigate to DMZ Services Relay.
    ADDITIONAL INFORMATION:
    The EMS server displays the Relay Services page.
  4. In the Reverse Proxy tab, click Add.
  5. On the Add Reverse Proxy Profile page, administer the following options using Relay Services field descriptions for reference:
    1. In the Service Name field, type the reverse proxy profile name.
    2. Select the Enabled check box.
    3. In the Listen IP field, select the external SBC IP address.
      ADDITIONAL INFORMATION:
      The IP address must be different from the IP address used for SIP signaling and media interfaces.
    4. In the Listen Protocol field, click the protocol published towards remote workers for downloading the file or firmware.
      ADDITIONAL INFORMATION:
      If you select the HTTPS protocol, the system enables the Listen TLS Profile field.
    5. In the Listen TLS Profile field, click the TLS profile that you created.
      ADDITIONAL INFORMATION:
      The default TLS profiles such as AvayaSBCServer have demonstration certificates. For optimum security, Avaya recommends that you do not use demonstration certificates.
    6. In the Listen Port field, type the port for remote workers.
      ADDITIONAL INFORMATION:
      For HTTPS, the default value is 443. For HTTP, the default value is 80.
    7. In the Server Protocol field, click the protocol used for the Avaya SBC server.
      ADDITIONAL INFORMATION:
      For security reasons, Avaya recommends the use of HTTPS. If you select the HTTPS protocol, the system enables the Server TLS Profile field.
    8. In the Server TLS Profile field, click the TLS profile that you created.
    9. In the Connect IP field, click the IP address that Avaya SBC uses to communicate with the file servers.
    10. In the Server Addresses field, type the server IP address and port number.
      ADDITIONAL INFORMATION:
      Note:
      Using the same IP address, you can configure multiple reverse proxy services for different listen ports. To reuse a port, configure a different IP address through Network Management.
  6. In the Reverse Proxy Policy Profile field, click a reverse proxy policy profile.
  7. To enable rewriting URL for the Converged Conference feature, do the following:
    1. To redirect the URL to a different URL, select the Rewrite URL field.
    2. In the URL Replace field, type the URL that the system must use to replace the current URL.
  8. Click Finish.
