Ending an Audio-only Call
To hang up from an audio-only call:
1. Press Hang Up on the remote control.
2. If prompted, confirm that you want to disconnect from the far site(s).
Participating in an Encrypted Call
If encryption is enabled on the system, a padlock icon appears on the monitor
to indicate whether a call is encrypted or unencrypted.
• 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: if all connections in the call are
encrypted, if one or more connections in the call are not encrypted.
In one call, some connections might be encrypted while others are not. The
padlock icon might not accurately indicate whether the call is encrypted if the
call is cascaded or includes an audio-only endpoint. To avoid security risks,
Polycom recommends that all participants communicate the state of their
padlock icon verbally at the beginning of a call.
Controlling What You See
Selecting and Adjusting a Camera or Other Video Source
You can use the remote control to select and adjust the main camera or any
other near-site or far-site video sources, such as document cameras,
computers, VCRs, or DVD players. You may be able to adjust other auxiliary
cameras or far-site cameras that support pan, tilt, and zoom movement.
If the person on the telephone hangs up first, you need to disconnect the call from
the Polycom HDX system, just as you would hang up a telephone receiver in a
regular phone call.
You can adjust the far-site camera only if it is configured to allow you to control it.
