The Polycom PVX software will usually operate satisfactorily after
installation without any modifications to the configuration.
However, it is possible to modify the settings at any time to
correct connection problems and/or change how the system is
configured. To make changes, click on the setup icon
found in the top left portion of the PVX screen. This wrench will
allow you to adjust various features within the program.
The Setup screen displays 4 buttons at the bottom:
Restore factory settings (requires restart of PVX)
Accept all changes and exit setup screen
Reject all changes and exit setup screen
Accept all changes and remain in setup screen
General:
General tab - user information
- User Name: enter the identifier you want displayed as
part of a directory listing (ILS). This is not a Username
used for logging onto a system.
- Email: enter your e-mail address.
- Select Language: click on the arrow to select the
appropriate language of choice.
- Always On Top: selecting this option may be
bothersome if you will be showing your desktop since the PVX
display may block portions of the desktop display. However, if
you use a dual-monitor PC this may be convenient since the PVX
display could be moved to the second monitor.
- Auto Start in Background: this option is convenient
if you do a lot of videoconferencing.
- Device Preferences: unless you are using a
Polycom ViaVideo camera,
select the "Never Use" option.
General:
Call Settings - convenience features
- Auto-Answer: this option is generally not
recommended for privacy reasons since the video camera
becomes active when an incoming call is received. If not
checked you will be prompted when an incoming call is
received. Camera will only be turned on after you accept the
call.
- Mute Auto-Answer: if auto-answer video is
selected it is highly recommended this option is selected
for privacy reasons so microphone is muted until local user
decides to activate the microphone.
- Maximum Time in Call: it is best to enter some
reasonable time limit to ensure connection is terminated if
accidentally forgotten.
- AES Encryption: unless there is a need for
encrypting the transmission, select "Off".
- Call Forwarding: if incoming videoconference
calls will not be accepted on the PC, select the appropriate
option(s) and enter the IP address of the videoconference
unit that should receive the forwarded call.
General:
Performance - allocate resources to the
preferred function on the PC
- PC Configuration: the PVX program will try to
detect and display the type and speed of the local PC
processor. If nothing or incorrect info is displayed,
check the box and select the closest match from the
pull-down menu.
- Allocate Resources: select your preference
for application priority. If your primary use is to be
showing your desktop, select "Other Applications". If
primary use during videoconference is the audio/video,
select "Polycom PVX". Otherwise, "Balanced" provides
equal priority to both desktop applications and the
videoconference.
- VideoMail Quality: The options are "Good",
"Better" or "Best". As quality is increased, so is
the size of the attached video file. Select the option
that provides an acceptable video quality without
creating too large of a file size.
Video:
Video Sources - camera selection and video
protocols activated
- Preferred Camera: if one or more video
cameras are connected to the PC it is important to
identify the specific camera to be used. Select the
appropriate camera from the pull-down menu. If no
camera is available, select "None".
- Send Image: if no camera is available
(i.e., broken) or selected ("None") it is still
possible to send a fixed image by selecting a
graphic image located on the PC. The image can be
either a BMP, JPG or JPEG image format. (This does
not work with all remote systems)
- Video Protocols:
- People+Content: enable - used to show

Directory:
- Internet Locator Server:
IFAS supports an ILS. By registering
with the ILS you will be able to see
in your directory a list of all
other videoconference sites that are
available and registered on the same
ILS server. Enter the IP address (ils.ifas.ufl.edu)
including the port number (1002)
separated by a colon. Check the
"Register" box and the "Status"
should show "Registered" if the
server is available and the IP and
port number were entered correctly.
- Global Directory Server:
GDS servers are not available for
IFAS use. Remove any GDS entries
and/or uncheck the "Register" box.
- H.323.Extension: enable -
required for use with the UF
Radvision gatekeeper.
- ISDN registration:
disable - ISDN telephone support is
not available.
Network:
Connection
- Choose connection type - select the type of
connection used by your PC. If unsure, call the IFAS Help Desk.
- Network adapter - check the Windows default adapter
unless another adapter is being used.
Network:
Ports - use the port range from 3230-3237.
Network:
QoS - no entry required. Quality of Service (QoS) is
not supported to the desktop.
Network:
Bandwidth
- Default - select 384 KB unless available
upload speed is less. Cable and DSL connections may have
speeds of 1.5 MB or more download but may only have a 256 KB upload speed
(asymmetric). In this case, select 256 as the default unless
the connection line is shared with others at your site. When
network connections are shared, select a default speed that
is lower than the max upload speed to allow others network
access.
- Maximum - in general, set to same value as the
default value used unless excess network bandwidth is
available (i.e., on campus).
- Asymmetric - if cable or DSL connection, check
the box. Enter the maximum upload speed of the connection.
- Dynamic - check the box
Speeds: check up to 6 call speeds between 128 and the
maximum transmit bandwidth available on the local network
connection.
H.323:
- Gatekeeper - select "Off" unless connecting to
a Gatekeeper for multi-site conference.
Gatekeeper
setup instructions are available elsewhere.
- Name - will display name as previously entered
on General Setup screen.
- Extension - enter "79" +
the last 5 digits of your local room phone number (i.e.,
7924636 for 392-4636). This number must be unique from all
other users on the Gatekeeper.
- PathNavigator - unchecked, not available.
SIP - uncheck, not used or available at this time.
GMS - uncheck, Global Management System is not used
or available at this time.
Stats: Call Statistics - when a videoconference is
in progress this page will display the connection speed,
connection quality and time for the video and audio
components of the call. If AES encryption is enabled, the
transmit (Tx) and receive (Rx) speeds will also be
displayed
Stats: Media Statistics - when a videoconference is
in progress this page will display specific details about
the connection speed and quality for both the transmit (Tx)
and receive (Rx) stats for both the video/audio and the data
parts of the connection.
Locks: Page Access - each setup feature can be individually
locked to prevent modification without the use of a password. This
is useful on PC systems that are used by multiple users. On single
user systems this feature is of little value unless you want to
prevent accidental modification of the setup parameters.
Locks: Feature Access - specific functions can be
individually locked to prevent modification without the use of a
password. This is useful on PC systems that are used by multiple
users. On single user systems this feature is of little value unless
you want to prevent accidental modification of the setup parameters.
Alert: this optional screen is used to monitor selected
components of the videoconference system. All components with a
check in front of them will be continually monitored.
