Types of Video Calls You Can Make

Participating in an Encrypted Call

Polycom, Inc.
To hang up a call:
>> From the Call screen, touch Hang Up.
If prompted, confirm that you want to hang up.
Depending on your system configuration, you may be able to make calls using
H.323 or SIP. By dialing call networked and public sites, you may be able to
use these protocols:
• SIP URI
• E.164 format
• Host name
• IP address
E.164 format: If you need to dial an extension (E.164 address), enter the
extension in the second entry field. If your system is not configured with a
second entry field, you can enter the extension when the gateway prompts you.
You can also specify characters in the dial string as instructed by the system
administrator.
If encryption is enabled on the system, a locked padlock icon
the monitor screen when a call is encrypted. If a call is not encrypted, an open
padlock appears on the monitor screen.
• If you are in a point-to-point call or a multipoint call hosted by another
system, the padlock icon displays the state of your individual connection.
• If you are hosting a multipoint 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 may be encrypted while others are not.
However, the lock icon may 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. To avoid security risks, Polycom recommends
that all participants communicate the state of their padlock icons verbally at
the beginning of a call.
