Purpose
Use this command to display registered Cisco
Unified IP Phones and their capabilities. The show
ephone command also displays authentication and
encryption status when used for secure SCCP SRST.
In this example, authentication and encryption status
is active with a TLS connection.
Use this command to display Cisco IP Phone status
and quality for all phones that are off hook. In this
example, authentication and encryption status is
active with a TLS connection, and there is an active
secure call.
