SIP server, the access code of the
near-site gateway, the speed code, and
the ISDN number of the far site. Contact
your system administrator for more
information.
When you call an IP system through a gateway that requires an extension (E.164
address), enter the extension in the dialing field whenever possible. Check with
your network administrator for the extension delimiter you will need to enter into the
dialing field. For example, some networks use ## to separate the extension from
the IP address.
When you include the extension, you will be given the option of saving both the
number and the extension in the directory when the call ends. If you enter the
extension after the gateway connects, you can save only the gateway number when
the call ends.
Placing Audio-only Calls and Adding Audio-only Sites
You may be able to use your Polycom HDX system to place an audio-only call
or add an audio-only call to a video conference.

User’s Guide for Polycom HDX Desktop Systems
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.
Using Your Polycom HDX 4000 Series as a Computer
Monitor
You can save space in your office or conference room by also using the
Polycom HDX 4000 series display as your computer monitor.
Check that the computer video is configured to use one of these supported
resolutions and refresh rates:
ResolutionRefresh Rates (Hz)
VGA (640 x 480)60, 72, 75, 85
SVGA (800 x 600)60, 72, 75
XGA (1024 x 768)60, 70, 75

SXGA (1280 x 960)60
SXGA (1280 x 1024)60, 75
WSXGA+ (1680 x 1050) - Recommended60
To use your Polycom HDX 4000 series system as a computer monitor:
1. Connect your computer to the Polycom HDX 4000 series system as shown
on the setup sheet that came with the system.
2. Press View Computer on the keypad to toggle between
displaying content from the computer and showing video from the video
conferencing system.
If your computer is a laptop, you might need to press certain function keys
to send video out of the laptop’s VGA port like you would when sending
video to a projector.
If you use the Polycom HDX 4000 series display as your computer monitor, Polycom
recommends that you set up the system so that calls must be answered manually.
This ensures that callers do not unexpectedly see or hear you at your desk.
