Call security is identified by the presence of the security icon present during an active call, as shown
in the following example.
The presence of the security icon is the only visible indication that the media path is encrypted. The
presence of this icon depends on whether the IP Deskphone has been configured to support SRTP
or not and is visible when the IP Deskphone is not in the idle screen.
Available SRTP configurations are provided in the following table.
