Feature Description Audio/Video Calls , 172.16.254.), you may hear a ringing sound for approximately 90 seconds. Until the ringing ceased, you were unable to place another call. When placing a video call, you may have heard the audio from the far - end site before you heard the ring tone or sa w the video. When entering H.323 names on the Admin Settings IP Network screen in the HDX web UI, you can now enter names that contain spaces. For example: My office HDX When entering Gatekeeper + H.323 extensions in Favorites or in the local direc tory, you can now use this simplified format for point - to - point calls: &#xGate;&#xkeep;r I;&#xP Ad; res;&#xs000;Gatekeeper IP Address##Extension for Primary xte;&#xnsio;&#xn200;Codec;Extension2; xte;&#xnsio;&#xn300;xte;&#xnsio;&#xn400;Extension3;Extension4 For example: 172.25.100.200##25567;25568;25569;25570 When using the HDX web UI to creat e a new contact, you can now enter the address using the E164@GatekeeperIP format in the IP Address field. For example: 123456@123.123.123.123 9 Known Issues and Limitations For Users The following table lists the known issues relevant to RPX end users. A ll issues apply to RPX systems with the Polycom Touch Control as well as to RPX systems with the Crestron Touch Panel unless otherwise noted. Feature Description Workaround Audio/Video Calls The RPX will not accept any incoming audio calls when it is al ready in a video call. Place outgoing audio calls instead of receiving incoming audio calls when you are already in a video call. On rare occasions, pressing the audio Speed Dial button once (or the Dial button for manually placed calls) does not dial th e call. If needed, press the audio Speed Dial button or the Dial button twice in order to complete the 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. None If the projectors are in sleep mode when an incoming video call is automatically accepted by the RPX, it may take up to 70 seconds for the projectors to automatically power up. During the 70 seconds that it takes for the projectors to warm up and show far - end vi deo, the RPX meeting participants may not notice that the call has been established. Verify that the projectors are powered up before placing or receiving any video calls. If the projectors are in sleep mode when a video call comes in, any codecs that a re not being used will 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 a RPX 400 on the near end receives an incoming call from an RPX 200 on the far end, or when eith er an RPX 400 or 200 receives an incoming call from a single endpoint (VSX or HDX). None If you hang up an incoming audio call and then immediately place an outgoing audio call, the RPX may not hang up the initial incoming audio call. Wait five seconds between consecutive audio calls. If the RPX 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 RPX is disabled, an incoming call from a two - codec or three - codec system will cause the center camera on the RPX to momentarily move to the side before returning to its correct position. None 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. Hang up the VMR call and then make a new call with the participants that you w ant in that call. 10 Feature Description Workaround Audio/Video Calls (continued) When you place a call to an RMX VMR using the following syntax, the call will not go through: IP##MeetingRoomID. Place the call using this syntax: MeetingRoomID@IP (for example, 255000@172.25.130.21 ). I f you use Meeting Composer™ to add two audio sites to a call and then press Join , only one of the sites may connect. Additionally, if you are already in a call that includes an audio site and you attempt to add another audio site to the call, the new audio site may not connect. Connect to the video sites first using the RMX, and then individually add the audio sites. TIP When an OTX 300 or RPX 400 Series system is in a point - to - point call with a CTS 3000 system, the call speed is limited to 2M per codec and 720p/30 resolution . None When an OTX 300 system is in a CTMS call with an RPX, CTS, or another OTX system, the OTX 300 system may not receive audio from the CTS system. Hang up and dial again. When connecting a Polycom RPX 400 Series system to a Cisco telepresence syst em that has fewer screens (such as a CTS 1300 or CTS 300), the OTX system only sends video from the Primary HDX codec. The RPX system is not currently capable of sending alternate video streams based on the active speaker to a system with fewer screens. N one Content 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 image renders correctly. None For VGA content, a shift of 2 - 3 pixels may be seen lo cally and a shift of up to 5 pixels on the far end. None Document Cameras The Eye - 10 document camera used in some custom solutions does not support the Freeze function that is available for other document camera models. None User Interface: Both Polycom Touch Control and Crestron Touch Panel In an audio call from an RPX to a cellular phone or analog phone, if the remote user disconnects the call first, the Touch Panel continues to show the audio call as in progress. Manually press the Hang Up button afte r each audio call is completed. The RPX will not accept incoming audio or video calls when the Hang Up button is off hook. User Interface: Crestron Touch Panel Only If you press the Content button on the Touch Panel when no content source (such as a lap top) is connected to the RPX with the VGA cable, the Primary HDX codec will generate a hidden message on the Primary wall screen. The message states "PC input resolution and/or refresh rate not supported.” This message will not be visible onscreen because the RPX is programmed to picture mute all wall screens 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. Wait three seconds (during which time the message will t ime out) before placing a video call from the Touch Panel. 11 Feature Description Workaround 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. None User Interface: Crestron Touch Panel Only (continued) 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: 123 456@172.25.130.201), the string will likely be truncated when displayed in the right - hand pane of the Touch Panel. None 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 o n 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 grayed - out. None When Polycom Conferencing for Microsoft Outlook (PCO) is used to schedule multiple meetings and you selec t 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. Select a different meeting from the meeting list. The Touch Panel may indicate that a password is not required for meetings that actually are password - protected. If you try to join the meeting, the Touch Panel will prompt you for the password and you must enter it to join the meeting. None If you use the DTMF dial pad in the Touch Panel Enhanced UI to manually enter a site to call, and then you try to escalate the call from point - to - point to multipoint, the ca lls will not connect correctly. Use the Meeting Composer dial pad to manually enter a site to call. The DTMF dial pad in the Enhanced UI was not intended to be used to manually dial calls and should never be used for this purpose. User Interface: Polyc om Touch Control Only If your system administrator has configured your system to use the calendar feature and you have two or more meetings scheduled at the same time, the Polycom Touch Control will display a meeting reminder for only one of the meetings. None If you are already in a call, you cannot join a meeting using the Polycom Touch Control. Hang up the current call before joining a meeting. When using the Polycom Touch Control, searching within a group in the global directory may not work proper ly. None If you are in a multipoint call and you place an outgoing audio call while the Video/Audio Only toggle button is set to Video , that toggle button will disappear from the Polycom Touch Control screen. When placing an audio call when you are alrea dy in a multipoint call, make sure that the Video/Audio Only toggle button is set to Audio Only . 12 For Administrators The following table lists the known issues relevant to RPX HD administrators. All issues apply to RPX systems with the Polycom Touch Contro l as well as to RPX systems with the Crestron Touch Panel unless otherwise noted. Feature Description Workaround Audio/Video Calls 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 th e 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. Specify multiple addresses in the IP address field (e.g., 76223; 76224;7622 5 ). Alternatively, use the web UI to connect to each codec individually at the desired call speed. 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 t he following conditions exist: 1. The RPX 200 Series or RPX 400 Series is in a single endpoint video call with a VSX or HDX video conferencing system (video ad - hoc dialing). 2. The RPX 400 is in a video call with an RPX 200 Series, a TPX ™ 306M, or a TPX 204M. T o 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 valu e 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. When the R PX is in a call, sending Telnet commands to change the video format may not work properly. Do not use Telnet commands to change the video format when the RPX is in a call. When an RPX calls another RPX in a point - to - point call, the codecs begin to conne ct one at a time. If network resources become limited, not all of the codecs may connect, which may make it appear that one of the projectors is not working properly. If a projector does not work correctly in a call, you should check if the codec connecte d. If it did not connect, reducing the call bandwidth may solve the issue. 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. None Control System When you connect to the codecs through Telnet or through the Crestron Toolbox and use the command prompt, you may see “overflow buf fer” and other error messages when you use the Touch Panel. These errors also appear on the Crestron log. This issue does not affect system performance or functionality. None Microphones If you disconnect the Polycom Ceiling Microphone Arrays and then con nect any microphones other than Ceiling Microphone Arrays, the proper stereo settings may be lost. 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. 13 Feature Description Workaround Software Installation and Upgrades When installing the Polycom Touch Control operating system and software using the USB drive, the software may fail to load or you may see a message listing an incorrect software version. Manually reboot the Polycom Touch Control while the USB device is in the drive. When attempting to unpair the Polycom Touch Control from the System Controller during an upgrade, the Polycom Touch Control may remain paired. Manually reboot the Polycom Touch Control to unp air it. 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 Hom e screen will appear on the displays when the upgrade is complete. None Telepresence Tool 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. User Interface: Both Polycom Touch Control and Crestron Touch Panel If any of the HDX codecs are rebooted without rebooting the AV2 System Controller as well, the HDX UI remains onscreen. Reboot the AV2 Sy stem 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. User Interface: Crestron Touch Panel Only If you add a site from the CMA directory to the speed dial list and then later change the name of t hat site in the CMA, the speed dial entry name that is displayed on the Touch Panel may not be updated. Reboot the codecs and the AV2 System Controller. Alternatively, from the HDX - add the renamed CMA site to the Speed Dial list. If you reboot the Primary HDX codec while the RPX is in an audio call (with the Help Desk, for example), the Hang Up button on the Touch Panel will freeze. Reboot the AV2 System Controller when the Hang Up button enters that frozen state. 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. None 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. With the Crestron Touch Panel, using the suffixes „1‟, „2‟, „3‟, or „4‟ for your audio speed dial name entries may cause the system to incorrectly interpret them as an ITP system, instead of distinct audio speed dial entries. Do not use the suffixes „1‟, „2‟, „3‟, or „4‟ for your audi o speed dial name entries. 14 Feature Description Workaround User Interface: Polycom Touch Control Only If you enter a site name that ends in the number „1‟, „2‟, „3‟, or „4‟ , and then you make a call using the RMX, the RMX will interpret the site as part of an ITP system and will not dis play the site name on the Polycom Touch Control. Do not use site names that end in the numbers „1‟, „2‟, „3‟, or „4‟. When you view the Directory list or the Favorites list on the Polycom Touch Control, the entries do not appear on the screen, although t he rest of the screen appears as normal. Reboot the Polycom Touch Control. If you reboot the Polycom Touch Control and then immediately attempt to use it, the Touch Control may not work properly. Wait 30 seconds after the reboot completes before using th e Polycom Touch Control.
