Configure trusted certificates feature.
In TLS feature, we use the terms trusted and server certificate. These are also known as
CA and device certificates.
Resetting the IP phone to factory defaults will delete custom certificates by default. But
this feature is configurable using the configuration files. For more information on the
configuration parameter, refer to Transport Layer Security on page 493.
