Selecting a minimum TLS version

Last Updated : Jun 10, 2026 |

About this task

You can select a minimum TLS version that Avaya Aura® Device Services uses to establish secure connections. Avaya Aura® Device Services supports TLS versions 1.2 and 1.3.

  • If you select version 1.2, Avaya Aura® Device Services can use either TLS 1.2 or 1.3 to establish connections.

  • If you select version 1.3, Avaya Aura® Device Services only uses TLS 1.3.

For security reasons, Avaya recommends that you use TLS 1.3 whenever possible.

Note:

Switching between TLS versions might cause considerable Avaya Aura® Device Services downtime because it affects DRS synchronization. Therefore, Avaya recommends that you switch TLS versions during maintenance windows.

Before you begin

Ensure that all deployment components that interact with Avaya Aura® Device Services over TLS support the TLS version that you plan to select.

Procedure

  1. Log in to the Avaya Aura® Device Services web administration portal.
  2. Navigate to Security Settings > TLS Configuration.
  3. In Minimum TLS version, select an appropriate TLS version.
  4. Click Save.
