The default mode is Discussion, however, your administrator may have set any of the following modes as
the default for your system:
• Auto - The view switches between continuous presence and full screen, depending on the
interaction between the sites. If multiple sites are talking at the same time, continuous presence is
used. If one site speaks uninterrupted for at least 15 seconds, that site appears in full screen on the
monitor.
• Discussion - Multiple sites are displayed in continuous presence. The current speaker's image is
highlighted.
• Presentation - The speaker sees continuous presence while the other sites see the speaker in full
screen on the monitor.
• Full screen - The site that is speaking is shown in full screen to all other sites. The current speaker
sees the previous speaker.

Encryption and Security
When a call is encrypted, a locked padlock
padlock displays on the screen. The padlock icon also displays in the following situations:
• If you are in a point-to-point call or a conference call hosted by another system, the padlock icon
displays the state of your individual connection.
• If you are hosting a conference call, the padlock icon displays the combined state of all
connections: encrypted if all connections in the call are encrypted, unencrypted if one or more
connections in the call are not encrypted.
In one call, some connections might be encrypted while others are not. However, the padlock icon might
not accurately indicate whether the call is encrypted if the call is cascaded or includes an audio-only
endpoint. If encryption is required on your system, the far-end must support encryption or the call will not
be completed.
Note: To avoid security risks, Polycom recommends that all participants communicate the state of their
padlock icons verbally at the beginning of a call.
Change the Call Security Level
When enabled by your system administrator, a visual security classification indicator displays during a call
to help participants be aware of the maximum level of classified information they can safely exchange in a
conversation. After a call begins, the visual security classification indication of the call displays on all
endpoint monitors in the call. During a call, you can override the security classification and assign a lower
security classification level. While you can change the security level, you cannot raise it higher than the
default setting.
