[. . . ] To avoid this issue, 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 twocodec or three-codec system will cause the center camera on the RPX to momentarily move to the side before returning to its correct position. 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 video, the RPX meeting participants may not notice that the call has been established. To avoid this issue, 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 are 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 either an RPX 400 or 200 receives an incoming call from a single endpoint (VSX or HDX). 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). 7 Feature Audio/Video Calls Description 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. If you share content using a laptop, for best results, set its input resolution to 1024x768 and its refresh rate to 75 Hz. The Eye-10 document camera used in some custom solutions does not support the Freeze function that is available for other document camera models. If you press the Content button on the Touch Panel when no content source (such as a laptop) 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. 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 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. To avoid this issue, manually press the Hang Up button after each audio call is completed. The RPX will not accept incoming audio or video calls when the Hang Up button is off hook. [. . . ] 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. To avoid this issue, reboot the AV2 System Controller when the Hang Up button enters that frozen state. Occasionally, the incorrect video format will be displayed on the Touch Panel Admin screen. If Video Quality=Sharpness, the video format is 1080p30; if Video Quality=Motion, the video format is 720p60. [. . . ]
