The phones support the following Trust on first use scenarios:
  • A new, out of the box phone, or a phone after resetting to default, that attempts to connect to the provisioning server using TLS.
  • The provisioning server presents its identity certificate, but the phone does not have any CA Certificates configured.
  • The phone will accept the presented server identity certificate given the above Server certificate validation passes except for the trust CA certificate chain validation
    Note:
    Trust on first use only applies to a TLS connection to a provisioning server, it does not apply to services such as SIP, LDAP or Syslog,and others.
