The N510 supports TLS for provisioning and phonebooks, the following version is supported:

  1. TLSv1.1 (From software 245 or higher)
  2. TLSv1.0

There is a provisioning parameter that can be used to change the behavior.


0x0302 = TLSv1.1
0x0301 = TLSv1.0 (Default)

If you would like to use TLS version 1.1 you can:

  1. Install the patch
  2. Change via auto-provisioning


  1. Download this configuration file.
  2. Open the web-interface of the N510 and go to: Settings - Management - Save and Restore.
  3. Select this file and press Restore.
  4. The N510 will reboot and then TLSv1.1 is enabled. The other settings are not changed.


Add this parameter to your provisioning template.
