For detailed information, refer to the "Configuring Encrypted Phone Configuration Files" chapter in Cisco Unified Communications Manager Security Guide.A phone requests a configuration file whenever it resets and registers with Cisco Unified Communications
If so, install Cisco Phone firmware load 8.5(2). For SIP phones, a TLS connection requires that the transport protocol in the phone configuration file be set to TLS, which corresponds to the transport type in the SIP Security Profile I also switched the tftp from Publisher to a subscriber server.Solution : I manually added each phone to the system since they were few phones.
It's okay! Once you delete the DN that was associated with the phone, then reset the phone, it should Auto Register once again. Thank you.
