The following table lists the other issues fixed in OTX version 2.7.1.
Feature Description
Audio/Video
Calls
Cameras
Touch
Panel/User
Interface
On rare occasions when placing a video or audio call with the Enhanced UI, the system may
have automatically dialed the number before you pressed the Connect button.
When viewing an RPX system in a 1080p multipoint call with an RMX 2000 or RMX 4000
with MPMx, you will no longer see a thin black vertical line between cells of the RPX system.
For more information, refer to the Polycom® ImmersiveTelepresence (ITP) Deployment
Guide.
The camera focus settings no longer drift over an extended period of time.
When joining a Polycom Conferencing for Microsoft Outlook (PCO) conference from the
Touch Panel, you were not prompted for a conference password, even if a password was
required for the meeting.
With PCO, private meeting details were displayed on the Touch Panel, even if the Primary
HDX system was not configured to Show Private Meeting Details.
On rare occasions with the Enhanced UI, you may have noticed that the speed dial and
directory information was not displayed properly on the Touch Panel. This typically occurred
following recovery from a power failure.
Known Issues and Limitations
For Users
The following table lists the known issues relevant to OTX 300 end users.
Feature Description
Audio/Video
Calls
4
The OTX will not accept any incoming audio calls when it is already in a video call.
To avoid this issue, place outgoing audio calls instead of receiving incoming audio calls when
you are already in a video call.
When DTMF tones are heard during the process of dialing an audio call, the near-end and
far-end audio is muted for a brief moment.
If the displays are in sleep mode when a video call comes in, any codecs that are not being
used will very briefly show near-end video. This only occurs when the number of near-end
codecs is more than the number of far-end codecs, such as when an OTX on the near end
receives an incoming call from an RPX™ 200 or a single endpoint (such as HDX™) on the
far end.
Feature Description
Audio/Video
Calls
(continued)
If you hang up an incoming audio call and then immediately place an outgoing audio call, the
OTX may not hang up the initial incoming audio call.
To avoid this issue, wait five seconds between consecutive audio calls.
If the OTX is in a single endpoint video call (such as with a VSX or HDX video conferencing
system) and the Do Not Disturb feature on the OTX is disabled, an incoming call from a twocodec or three-codec system will cause the center camera on the OTX to momentarily move
to the side before returning to its correct position.
If you place a point-to-point call to an RMX™ Virtual Meeting Room (VMR) and then add a
site to the call from the Conference List on the Meeting Composer screen (with the Enhanced
UI only), the point-to-point call will be dropped and a multipoint call will be created with the
VMR as a participant in that multipoint call.
To avoid this, hang up the VMR call and then make a new call with the participants that you
want in that call.
If you are using Meeting Composer and you dial two audio sites concurrently, the Touch
Panel may show that you are connected to the second audio number dialed when you are
actually connected to the first number dialed.
To avoid this issue, when want to connect to multiple audio sites or to both audio and video
sites when using Meeting Composer, connect to the video sites first (if any), and then add the
audio sites one at a time.
When you place a call to an RMX VMR using the following syntax, the call will not go
through: IP##MeetingRoomID.
To avoid this issue, place the call using this syntax: MeetingRoomID@IP (for example,
255000@172.25.130.21).
If you dial an incomplete IP address for a video call (for example, 172.16.254.), you may hear
a ringing sound for approximately 90 seconds. Until the ringing ceases, you will be unable to
place another call.
When the video quality is set to Sharpness, a thin gray line is present at the bottom of the
cells when connecting TPX and RPX endpoints to a conference running on RMX 2000 or
RMX 4000 with MPMx.
Content Occasionally, while in a call showing People+Content IP, the People+Content IP connection
Touch
Panel/User
Interface
will drop when the call ends and the tabletop content monitors will lower. To continue sending
content, you will need to use People+Content IP to send the content again.
If you share content using a laptop, for best results, set its input resolution to 1024x768 and
its refresh rate to 75 Hz. This will ensure that the content renders correctly.
If you press the Content button on the Touch Panel when no content source (such as a
laptop) is connected to the OTX with the VGA cable, the Primary HDX codec will generate a
hidden message on the Primary codec’s display. The message states "PC input resolution
and/or refresh rate not supported.” This message will not be visible onscreen because the
OTX is programmed to picture mute all displays when the system is not in a call. If you
establish a video call while the message is activated, the call will take longer than usual to
connect.
To avoid this issue, wait three seconds (during which time the message will time out) before
placing a video call from the Touch Panel.
In an audio call from an OTX to a cellular phone or analog phone, if the remote user
disconnects the call first, then the Touch Panel continues to show the audio call as in
progress.
To avoid this issue, manually press the Hang Up button after each audio call is
completed. The OTX will not accept incoming audio or video calls when the Hang Up button
is off hook.

Feature Description
Touch
Panel/User
Interface
(continued)
When searching for a site in the global directory with the Enhanced UI, up to nine characters
can typically be displayed on the screen. However, depending on the width of the letters in
the name, more or less of the site name may be truncated.
With Meeting Composer, when dialing a phone number with more than 10 digits, or dialing
any other long string such as extension@IP_address (ex: 123456@172.25.130.201), the
string will likely be truncated when displayed in the right-hand pane of the Touch Panel.
If you place a point-to-point call to an RMX Virtual Meeting Room (VMR) and then add an
audio-only site to the call, the two columns on the left side of the Meeting Composer screen
in the Enhanced UI will go blank and the icons at the top of the columns will become grayedout.
When Polycom Conferencing for Microsoft Outlook (PCO) is used to schedule multiple
meetings and you select one of the meetings on the Touch Panel, the details for that meeting
display on the left side of the Touch Panel screen. If that meeting is cancelled, it is removed
from the meeting list; however, the details of the cancelled meeting are still displayed on the
left side of the Touch Panel screen.
To fix this issue, simply select a different meeting from the meeting list.
For Administrators
The following table lists the known issues relevant to OTX 300 administrators.
Feature Description
Audio/Video
Calls
If you want your OTX 300 users to view close up or wide shot camera views when in a
multipoint call or in a point-to-point call with a traditional video conferencing system, you can
enable the UseCameraViews parameter in the System_Config.ini
“Enabling Close Up or Wide Shot Camera Views” section of the Polycom Immersive
Telepresence (ITP) Administrator’s Guide for details. Note that although the Administrator’s
Guide says that this optional feature is available for TPX® and ATX only, you can also
enable this parameter in OTX.
When the Primary codec answers an incoming video call, any HDX codecs that are not being
used will automatically accept any other incoming video calls if the following conditions exist:
1. The OTX is in a single endpoint video call with a VSX or HDX video conferencing
system.
2. The OTX is in a video call with an RPX 200 or a TPX 204M.
To prevent unused codecs from accepting any incoming calls, use the Do Not Disturb timer.
To change the amount of time before Do Not Disturb is activated, access the
DoNotDisturbTimer field in the System_Config.ini file. In this field, you can enter a value
between 10 and 300, or leave the value at 0 if you want to keep the feature disabled:
DoNotDisturbTimer=x where x is the value (in seconds) of the desired timeout
period.
For example, DoNotDisturbTimer=120 sets the parameter to 120 seconds.
If you use the web UI to place a call that is not at the default call speed, the codecs will not
automatically adjust to the same call speed. The Primary codec will connect at the call speed
specified in the HDX web UI Call Quality field, but the remaining codecs will connect at the
default call speed.
To avoid this issue when placing a call using the web UI, connect to each codec individually
at the desired call speed (if the desired call speed is different from the default).

Directory If you add a site from the CMA directory to the speed dial list and then later change the name
Avoid using the suffixes ‘1’, ‘2’, ‘3’, and ‘4’ for your audio speed dial name entries. Using
these suffixes may cause the system to incorrectly interpret them as an ITP suite, instead of
distinct audio speed dial entries.
Avoid creating directory entries that have an “&” symbol in the name. If you do so, the entry
will appear on the site list with the word “amp” in the name rather than the “&” symbol.
When the OTX 300 is in a call, sending Telnet commands to change the video format may
not work properly.
To avoid this issue, do not use Telnet commands to change the video format when the OTX
is in a call.
If your ITP environment is configured to use both the LDAP directory and H.323 Gatekeeper
functions, and your speed dial entries are not IP addresses, video calls may take longer to
connect due to the additional communication involved between the various components in
the solution.

To avoid this issue, whenever a camera loses power, the HDX codec that is attached to that
camera should be rebooted.

system performance or functionality.
of that site in the CMA, the speed dial entry name that is displayed on the Touch Panel may
not be updated.
To fix this issue, reboot the codecs and the AV2 System Controller. Alternatively, from the
HDX web UI, delete and re-add the renamed CMA site to the Speed Dial list.

other than Ceiling Microphone Arrays, the proper stereo settings may be lost.
If this occurs, launch the Polycom Telepresence Tool, make sure that all the HDX codecs are
connected, and then click Configure HDXs to set the microphones to their correct settings.
When upgrading the HDX systems, you normally see a screen that displays an hourglass
and a red progress bar. This screen may not appear for HDX PAL systems; however, the
upgrade is still occurring and can be monitored through the web UI. The Home screen will
appear on the displays when the upgrade is complete.
When using the Telepresence Tool to remotely monitor a site, you may notice stuttering
video.
Polycom recommends that you do not use the Telepresence Tool for remote monitoring while
the system is in a video call.
If any of the HDX codecs are rebooted without rebooting the AV2 System Controller as well,
the HDX UI remains onscreen.
To avoid this issue, reboot the AV2 System Controller whenever any of the HDX codecs are
rebooted. The VNOC, Service, and Site Administration teams are advised to reboot (power
up) the AV2 System Controller after the HDX reboots (powers up) as part of the reset
process or when recovering from a power failure. Placing a call without rebooting the AV2
System Controller will cause the Touch Panel to freeze.

Feature Description
Touch
Panel/User
Interface
(continued)
If you reboot the Primary HDX codec while the OTX is in an audio call (with the Help Desk,
for example), the Hang Up button on the Touch Panel will freeze.
To avoid this issue, reboot the AV2 System Controller when the Hang Up button enters that
frozen state.
Occasionally, the incorrect video format information will be displayed on the Touch Panel
Admin screen.
To determine the correct video format:
1. From the web UI, go to Admin Settings > Cameras.
2. Check the Video Quality field for the camera being used. If Video
Quality=Sharpness, the video format is 1080p30; if Video Quality=Motion, the
video format is 720p60.
Alternatively, you can check the Video Format on the web UI Place a Call page.
When initially loading the Crestron Touch Panel and then loading the AV2 System Controller,
a Toolbox Results dialog box may appear at the end of the installation process. Although this
dialog box displays an error message, the installation completed successfully.
If users report that the Touch Panel seems to take an unusually long time to return directory
information, check if there are LDAP entries in the directory that are no longer valid. If there
are such entries, correct them.
