Polycom VIEWSTATION EX Instruction Manual

June 2005
3725-21815-007/A
Polycom is pleased to announce the version 6.0.5 software release for Polycom ViewStation® EX/FX/VS4000
systems.
What’s New in This Release?
Polycom software release 6.0.5 is available as a free software update for ViewStation EX/FX/VS4000
customers. Version 6.0.5 addresses the issues described in the Corrected Issues table and includes the
following new functionality.
New Mixed IP and Gateway Dialing
With this version, the ViewStation EX/FX/VS4000 and MGC™gateway products operate
smoothly for sites transitioning to IP only and using the MGC gateway to perform all
necessary ISDN calls. In addition, the address book supports mixed gateway and IP calls.
IP-Only Sites
For a system to be truly IP-only, it must not have a V.35 or ISDN module connected to it.
The system works differently if you simply disable ISDN as a call preference type.
Differences in Dialing Addresses
The difference between a gateway call and an ordinary IP call is that in a gateway call, the
system attempts to prefix a number(s) to the ISDN number. When the dialing address
arrives at the gateway, the gateway can use the prefix to determine what call rate to dial.
With gateways you can also use E.164 addresses, which can appear to look exactly like
ISDN addresses, or an IP alias. This alias can be all alphabetic characters, and the
gatekeeper resolves the IP address in order to call the far site.
One Dial Preferences
The Primary Call Type can be ISDN, IP, or Manual, and the Secondary Call Type can be
ISDN, IP, or None. These settings affect ISDN/IP rollover scenarios. ISDN/IP rollover
occurs in the Manual Dialer when the call type is set to Auto and when dialing a single
address book entry with both protocol types filled in. In these scenarios, the system uses
the One Dial Preferences to decide what type of call to dial first based on the Primary Call
Choice. If that fails, it will try the Secondary Call Choice if it is not set to None. If the
Primary Call Choice is set to Manual, the call protocol should default to ISDN for the
manually dialed calls and the user should be prompted for address book dialed calls.
ISDN/IP rollover will never occur in a multipoint address book entry; however,
gateway-to-ISDN rollover described in the next section will occur.

Outbound Call Route Settings
The Outbound Call Route setting, Gateway or ISDN, controls gateway-to-ISDN rollover.
If this setting is set to ISDN, all ISDN calls will be made over H.320. If this setting is set to
Gateway, ISDN calls will first be tried over H.323 using a gateway, and if that fails, they will
be tried over ISDN. Note that ISDN calls will not rollover and try the gateway.
Multipoint Address Book Entries and Rollover Scenarios
Mixed ISDN/IP address book entries will never roll over from ISDN to IP but will roll over
from gateway to ISDN if the system is configured to make gateway calls. This behavior
occurs because you choose what protocol to use for dialing at the time you create the mixed
address book entry.
Gateway Calls and Speed Changes Due to Flow Control
This version uses an intelligent algorithm for deciding the dialing speed for a subsequent
gateway call if the preceding call's speed was decreased significantly by the gateway flow
control.
Single Address Book Entries and Call Type Rollover
The system now always tries to roll over and call out with ISDN, if a gateway call fails for
any reason. ISDN/IP rollovers occur based on the cause code.
Multipoint Address Book Entries on IP-Only Systems
In this version, for a four-way multipoint Address Book entry containing all IP call types,
the entry can be saved and the multipoint call placed at a maximum call speed of 384K on
all systems.
Disabling the H.264 Video Protocol
A new Disable H.264 checkbox has been added to the system and resides on the System
Options page. All systems which are H.264 capable, whether they require an option key or
not, will have H.264 enabled by default. You can disable H.264 by selecting the checkbox
and clicking Save before leaving the page. This option gives you the flexibility to
communicate through gateways that do not have this feature fully implemented.
API Enhancements
Telnet port 24 can now continue to accept connections if the previous connection
terminated for any reason. When the first connection goes down, a second is able to
reconnect to port 24. The ViewStation EX/FX/VS4000 system deems the first connection
inactive and closes it after 30 seconds of no incoming data. This behavior is not designed
to service two simultaneous connections to port 24, but prevents a single connection from
hanging and the need for a system reboot to clear this condition.

If both connections on port 24 are active and there is no room for another incoming
connection, then the ViewStation EX/FX/VS4000 system properly refuses this incoming
connection with a Port Disconnect message.
Corrected Issues
The following table lists issues corrected in version 6.0.5.
Feature Limitation
Address Book An Address Book file left over from the
ViewStation EX/FX/VS4000 release 4.2 did not use the
proper speed to call. This has been corrected.
The system address book has been updated to provide a
new ISDN phone number for the Polycom Austin location.
The 6.0.5 Softupdate package will automatically provide
the user with the new number after the upgrade is finished.
Camera When the alternate PTZ camera was used for a snapshot,
it went back and forth to the home location before or after
the snapshot. This has been corrected.
Communication If a user registered with a gatekeeper and made the
systemanIP-only system byunplugging the network cable
between the ViewStation EX/FX/VS4000 system and PRI
module, the PRI icon and the gatekeeper icon on the main
screen alternately flashed yellow. This has been corrected
to show the PRI icon red and the gatekeeper icon green.
Internal MCU When in a point-to-point call with VSX™systems at call
speedsof384Korlessandusingthe H.264 video protocol,
the ViewStation EX/FX/VS4000 system had trouble
negotiating video down to H.263 after adding another site
and becoming an MCU. This issue has been corrected.
WhenaViewStationEX/FX/VS4000systemwasoperating
as an MCU in a three-way or four-way mixed protocol
conference, if the user hung up one of the H.320 systems,
sometimes video would freeze at the other sites and not
recover unless an action occurred in the UI to force the
MCU to renegotiate caps with the other active sites. This
has been corrected.

People+Content™If a user made a three-way H.323 conference with two
iPower™systems and a ViewStation EX/FX/VS4000, with
one of the iPower systems serving as the MCU, and the
user sent content from the non-MCU iPower, the
ViewStation EX/FX/VS4000systemdidstopdisplayingthe
content after a few minutes. This has been corrected.
The ViewStation EX/FX/VS4000 system had a problem
advertising custom content video capabilities to systems
which could not transmit the content video properly,
causing display problems. This issue has been corrected.
PRI
Communication SystemswithPRImoduleslosttheB-channelswheneither an AT&T 4ESS or Nortel DMS PRI switch performed a
layer 1 hot switch-over and lost the D channel for any
length of time. This has been corrected.
Security If a user configured a system with an admin password and
tried to add the system to Global Management System™
(GMS) with the auto discovery feature providing the admin
password, GMS reported the endpoint could not be added.
The system now will allow the GMS to auto discover the
ViewStation FX system, provided the
ViewStation EX/FX/VS4000 admin password is different
than the unit's serial number.
Therewasan interoperability issue with encryption and the
Tandberg MXP software version F2.5, when the Tandberg
system was operating as an MCU with all H.323 calls at
384K. This has been corrected.
Snapshot When making a video call at speeds of 384K or less, which
enables the H.264 video protocol by default in a
point-to-pointcall,and the usersenta snapshot,the farsite
did not display the snapshot on the VGA monitor or on the
second monitor of a dual monitor configured system. This
has been corrected.
When making a video call at speeds of 384K or less, which
enables the H.264 video protocol by default in a
point-to-point call, and the system was configured to use
twomonitors,when a usersentasnapshot to it, the system
did not display the snapshot on either monitor. It would
display correctly if the system was configured for one
monitor. This has been corrected.
Streaming A user entering a meeting password was not allowed to
view a stream from the web browser. This issue has been
corrected.

Telnet/API During a Telnet session with the system, the reboot
command prompted the user with the "reboot,areyousure
<y,n>" prompt. If the user entered a capital 'Y' or 'N', the
system would respond with a "command not found"
message. This has been corrected.
When in an audio-only conference, the main monitor
togglesbetweennearvideoandthemainscreento prevent
the potential of burn in. You can stop this behavior by
preventing the system from goingto sleep. Use ftp to puta
file on the system named "sleeponnear.dat" with the word
"No." An alternative way to prevent the system from going
to sleep is to send the API command sleeponnear no
to set this file.
User Interface When the MGC was used for a conference and one of the
sites terminated its call, the other sites would see the
message "Join to Conference." This has been corrected.
V.35
Communication When a system was set up as a direct connect V.35 system, and the user selected Display Dialing Protocol
on the Dialing Preferences screen then rebooted the
system, the selection was no longer selected. This has
been corrected.
A V.35 Direct Connect system had a problem connecting
properly and displaying video at a call speed of 1536 with
a NEC system. This has been corrected.
Video Video would freeze in a three-way or four-way internal
multipoint conference making all H.323 calls. This has
been corrected.
Web Interface The user could create an address book entry with two
entries on a system which was configured as an IP-only
system and each entry had an IP address only with the call
speed set to 384K. If the user selected this address book
entry and made the call from the Web, a popup box
displayed "The system is not configured to support ISDN
calls."WhentheuserclickedOK,thesystemdialedthecall
properly. This has been corrected.
The system was not dialing properly when using the web
interface to dial calls through a gateway on an IP-only
system. This has been corrected.

video system.
Interoperability
MGC Version
7.0 Gateway
functionality only
The following configuration flags must be set to NO in the
MGC configuration file “system.cfg” in order for the
ViewStation EX/FX/VS4000 system and MGC gateway
functionality to work correctly:
GW_EPC_H239
FECC_GW
GW_H264
Note that with these flags set to NO, H.264, people +
contentand farend cameracontrol will notoperate through
the gateway.
Interoperability
Plasma Displays
IR interference may exist when the ViewStation
EX/FX/VS4000 is used with certain plasma displays.
Certain plasma display monitors (televisions) emit infrared
energy which interferes with the operation of the remote
control. Interference may include, but may not be limited to:
•Dropped characters or commands—the user presses a
button on the remote control and the number does not
display or the command is not received.
•Incorrect characters or commands—the video
conferencing system may receive characters or
commands the user does not enter on the remote
control.
•The remote control may not work as well at long
distances.
•This type of interference may be experienced with a
ViewStation EX/FX or with the PowerCam or PowerCam
Plus cameras as used with the VS4000.
Polycom recommends separating the camera from the
plasma display to avoid this interference.
Interoperability
RadVision vialP
v4.0 Gateway
To use the ViewStation EX/FX/VS4000 system’s internal
MCU capabilities using the gateway, disable H.264 from
the System Options page before making any point-to-point
gatewaycalls. Point-to-pointcalls workproperly with H.264
enabled; however, there are known issues with
renegotiating the video protocol to H.263 from H.264
through the gateway.
