The OTX 300 offers stunning HD video quality for up to 50% less bandwidth using Polycom's H. 264 High Profile compression technology. [. . . ] 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 RPXTM 200 or a single endpoint (such as HDXTM) on the far end. 4 Feature Audio/Video Calls (continued) Description 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 RMXTM 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. 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 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. Touch Panel/User Interface 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 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. 7 Feature Touch Panel/User Interface (continued) Description 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. [. . . ]
