Hardware compatibility Due to replacement of hardware components there are some constraints running older software on newly manufactured endpoints and Touch 8 devices.

This is due to end of life of some components and introduction of new components that require changes in the software. For a detailed list of compatibility levels and software constraints for the Cisco TelePresence systems please see the appendices in this document: Cisco TelePresence Systems hardware dependencies Cisco TelePresence Touch 8 hardware dependencies There is a lock, which prevents the system from downgrading to unsupported versions on endpoints as well as Touch 8 devices.

If a downgrade attempt fails it may be due to lack of Codec support or lack of Touch 8 support in the old software. New hardware revision of the Cisco TelePresence Codec C40 February , Cisco starts shipping a new hardware revision of the C40 Codec, which is not supported in older software versions except for TC 4. Information on serial number range will come in a later release note. The camera will work as a third party camera, but C-series codec software will not be able to upgrade the camera and it is therefore not recommended for use with C-series codecs.

Show the same participant in full screen mode for the entire call no voice switching between participants. Security warning when system password is not set There will be an on screen warning in the lower right corner indicating that the system password is not set.

The warning will also be displayed on the touch panel. The warning will disappear as soon as the password has been changed. This is a bugfix release. Please note that the encryption indicator padlock will indicate that the connection to the ISDN Link is secure, but does not guarantee the full end-to-end encryption as the ISDN Link does not have any way of determining full end-to-end encryption.

Down speeding in multisite You can now choose the total bandwidth. You set the total bandwidth to 4 mbit. When calling the third participant, all calls will be downspeeded to accomodate all three calls within 4 mbit. MaxTotalTransmitCallRate and receive is total bandwidth usage. If codec does not support p60 there will be no line mentioning p It is also possible to determine if p60 is supported in the main.

Example main. The upgrade will start when the endpoint initiates it. The endpoint itself sends continuous feedback throughout the process. The Bug Search Tool lists both open and resolved caveats. The power LED is up but no remote control and no video is coming from the camera. The time itself is correct. The CA list must be named sipcalist. CSCub Not possible to dial via directory. Logs from arms expect osd seem to be logged with U TC , while ppc log entries are formatted according to local time zone.

CSCub SX20 fan occasionally makes a loud noise. CSCub A stack based buffer overflow vulnerability is present in the facilities handling package extraction. Successful exploitation of this vulnerability can allow an attacker to execute arbitrary code with elevated privileges, and can be leveraged to forge software packages. CSCub It may be possible for an attacker to overwrite arbitrary files on the system, by getting an authenticated administrator to extract a specially crafted package file.

CSCub A locally authenticated administrator may execute arbitrary commands via the pkgextract utility using specially crafted package files. CSCuc The maintenance shell does not always kick in when the unit gets into a cyclic reboot. If system crashed less than 4 minutes ago it will enter maintenance mode rather than going into a reboot. CSCua SX20 date set to causes restart when placing a call.

When it is configured for half it still shows full. CSCtx If the config. CSCua If microphone is muted during a call, the icon turns red, and stays red after the call is disconnected. CSCtz This causes VPE1 to stop responding and system will boot on heartbeat failure. CSCty Random video blackouts in point-to-point calls with packet loss. This is by design in SIP and it will therefore block a video port on the receiving endpoint instead of an audio port.

The endpoint will therefore not be able to make a video call at the same time. The camera will operate as a third party camera. Camera control will work, but software upgrade is not possible. A TC P registered endpoint will not be able to make secure calls. This setting has to be set to off in order for the endpoint to register to VCS.

The reason is that failover is yet not supported. This incompatibility will cause the monitor to wake up from sleep mode even if the codec is still in sleep. A workaround is to use the DVI input of the monitors. This is a security measurement to prevent key logging from the remote control. Depending on the device you connect the camera to, you may not get video using this format. The Cisco C-Series codecs will support these formats. You must use Unix end of line to be able to run multiple commands.

Most editors have the option to set which format to use. The solution is to connect the cascaded camera as the first camera in the chain so that the camera is detected and upgraded by the codec, or use the Ethernet upgrade method. This is due to a jitter issue. No issues found in OCS R2. When presentation is started, the remote video is being replaced at first output display composite output with the presentation content; the second monitor DVI output also shows the presentation content.

CSCue Touch 8 All 6. CSCty EX90 5. After ending presentation the second monitor will be black. Encrypted calls are not supported in 8. If you use an H. Fixed in TS 2. Such a conversion will make the call drop. Black Screen Codes are supported, but these will not work if the system is behind a firewall. Bug is identified in TX software. Interoperability The main video frame rate will never exceed 15 FPS.

SIP encrypted calls does not work. Sony is unable to start presentation BFCP. Radvision XT 3. Upcoming fix on Radvision side. This is due to end of life of some components and introduction of new components that require support in the software. These methods are presented in the following.

Downgrading to an unsupported software version will fail. The latest software releases are always backward compatible with all hardware versions. The endpoints running TC software will be manufactured with a newer version of the flash memory. For simplicity in this document we will call the first flash version 0 and the second flash version 1. This section contains auxiliary devices that can be used with the TX systems:.

Note Using External Devices with Your Cisco TelePresence System —Cisco cannot guarantee the performance of any external device, so Cisco recommends that you choose good quality external devices to optimize the performance of your TelePresence system.

The Cisco TelePresence system works best when suitable devices are attached using good quality cables and connectors. Cisco does not supply the cable that connects auxiliary devices to the codec. This section describes the display choices you have with your Cisco TelePresence System and includes the following topics:.

Before use, turn off all on-screen display OSD capability for the displays. This prevents the display from showing messages after you stop sharing a presentation. Tip Perform these steps using the remote control that comes with the system, or use the joystick control on the back of the display.

Step 2 Press MENU on the remote, or press the center of the joystick and move the joystick to select the menu option the choice on the left , to bring up the menu for the display. Step 3 Using the up and down arrows, navigate to System in the menu panel. Step 4 Press Enter if using a remote, or press the center of the joystick if using the joystick on the display, to select the System choice.

Step 5 Using the up and down arrows, navigate to General and press either Enter on the remote, or the center of the joystick on the display. Note This choice does not appear initially. Scroll down to see it. Step 8 Press EXIT on the remote, or move the joystick to the previous menu choices, until the menu no longer displays.

Cisco highly recommends the use of commercial or professional-grade displays with your Immersive TelePresence system. Off-the-shelf consumer displays or TV monitors are not recommended, as they typically have shorter life spans and require a remote control to operate. When qualifying a display for use with your TelePresence system, consider the following:. The following WolfVision document cameras have been tested for use with TX systems:.

The following video signal splitters have been tested for use with the CTS systems:. During a point-to-point call, no video appears on remote H. During a H. The remote C40 system can still see the presentation. During an MCU conference between two TX endpoints an a C20 endpoint, when TX shares a presentation and then performs a hold-and-resume, the presentation appears green. Some TMS alerts and prompts appear even while the system is not in a call.

The call is dropped. The Polycom endpoint shares a presentation. The presentation is shown on the TX9x00 for only 3—4 seconds. For complete Cisco TelePresence software compatibility and device interoperability information, go to this page:. This section contains the following caveat information:.

Conditions This issue is present in the following circumstances:. Symptom Directories do not appear on the Touch device of your TelePresence system.

Conditions This condition is seen only when an endpoint running TX software release 6. Workaround There is no workaround. In some cases, performing a Hold, then a Resume on the endpoint fixes the audio problem. Symptom The power button for the document camera is grayed out.

Conditions This condition is seen after you manually power off the camera. The GUI shows three dots below the microphones, whereas the display does not show the dots. Conditions This condition occurs during microphone troubleshooting and does not affect system troubleshooting or the functioning of the microphone, only the appearance of the icons.

No audio can be heard during a video conference. Conditions This condition occurs after an upgrade from 6. Symptom During a point-to-point call between a CTS and a C40, the user shares a presentation, then changes the resolution of the display.

After the resolution change, the presentation could not be seen on the far side. Conditions This problem occurred under the following test conditions:. The CTS shared a presentation at a resolution of x The CTS performed a hold and resume operation. The CTS changes the resolution of the presentation to x After these steps were performed, the presentation was not seen by the C Symptom When a directory with a large number of entries , is searched on the Cisco Touch device, the search results are not consistent.

Conditions This condition occurs when there are a large number of entries in the directory. Symptom One-way video is seen at the start of a call between a Jabber client that has been configured to never start calls with video and a CTS or TX system. Conditions One-way video is seen under the following conditions:. CSCuj Now resolved in 6. CSCul Now resolved in 6. Conditions This condition may occur during a call between Jabber and some Cisco TelePresence systems. Symptom During a multipoint call, a multi-screen immersive system can be appear as a single-screen endpoint because of insufficient system resources insufficient ports.

In this case, the screen will not switch to the active speaker and remains on the center segment, even if no participants are in that segment. Conditions This condition occurs during a multi-point call using a TelePresence Server, and not enough ports were available for all three segments of an immersive system. Workaround Make sure that you allow the correct amount of resources during a multipoint call.

Symptom You experience one-way audio during a conference. Conditions The following conditions cause the issue:. This type of call is known as an interop call. Workaround Hold, and then resume, the conference. Symptom Video flashes or blinks on and off during a conference.

Conditions Users dialing in to a conference using the TelePresence server with a minimum release of 3. Workaround If your TelePresence server is running release 3. Symptom During an MCU conference between two TX endpoints an a C20 endpoint, when TX shares a presentation and then performs a hold-and-resume, the presentation appears green.

Conditions Issue occurs during an MCU conference. Workaround Unshare the presentation on CTS, then share again. Conditions Issue occurs after a CTS running 1. Symptom During a point-to-point call between a TelePresence endpoint and an interop endpoint, a third endpoint calls the interop endpoint, and the three endpoints enter a conference either an MCU or TelePresence conference.

If it is an MCU conference: after entering the conference, the TelePresence endpoint does not see any incoming video, and the shared presentation appears on the center screen. If it is a TelePresence conference: only XGA resolution is supported and all other resolutions are disabled. The conflict disables BFCP server mode. Workaround Press hold and resume on the TelePresence endpoint. Symptom When the administrator uses the TMS administrative interface to delete an active meeting, the TelePresence system exits the meeting but still shows the scheduled meeting and the Join button on the Touch Conditions Issue occurs when an active meeting is canceled by the administrator using the TMS administrative interface.

Workaround Wait for a few seconds until the meeting information and Join button disappear. Symptom Some TMS alerts and prompts appear even while the system is not in a call. Symptom Occasionally, the call duration timer on the Touch 12 device does not update immediately when a call starts.

Symptom The presentation freezes at the remote sites when content is being sent after hours on a call using the TelePresence Server. The presentation was frozen on all 1. CTS running 1. This condition appears whether the presentation display is a monitor or a projector, or is using an external presentation display.

The same condition is seen on systems using CTMS without the TelePresence Server; however this condition is seen after a longer time more than 13 hours. Conditions This condition is seen on CTS endpoints running 1. Workaround Press Hold and Resume to resolve this problem. Workaround If your Cisco TelePresence server is running release 3.

Symptom Security icon on CTS shows non-secure when in a secure conference. Conditions The conference is running on Telepresence Server 3. Symptom During a multipoint call where one participant is a Cisco Unified IP Phone connected via audio add-in, an endpoint shares a presentation. When the IP Phone goes on hold, the presentation on the endpoint that performed the audio add-in appears green or disappears.

Other endpoints can still see the presentation. Conditions One participant on an IP Phone is connected by way of an audio add-in; then, another endpoint shares a presentation. The IP Phone goes on hold. Workaround Perform one of the following actions:. Unshare, then share the presentation by tapping the UnShare option on the Touch Panel, then tapping Share. Disconnect and reconnect the presentation source by unplugging the presentation cable, then plugging it back in.

Have a non-host site that is not sharing the presentation add the audio-only participant into the call. Symptom During a point-to-point call between a TX9x00 system and a TX 65 system, a shared presentation may appear pixelated intermittently on the remote endpoint. Conditions This issue occurs during a point-to-point call between a TX9x00 system and a TX 65 system, where one system shares a presentation. Symptom For systems configured for TMS integration, the Join button appears on the Touch 12 ten minutes before the meeting start time, even if no setup buffer was configured.

The button does not work until the meeting start time. Workaround Configure a minute setup buffer using the TMS administration interface, which will allow the button to work. Upon reboot, the button functions correctly for 15 minutes before failing to work again. Symptom During a H. Conditions Issue occurs during an H. Workaround Change the presentation resolution to a higher resolution. Symptom When a TX user annotates a presentation shared from another endpoint, taps Done , and then performs a hold-and-resume, the annotations still appear on the TX Touch 12 device upon resume.

The Polycom endpoint shares a presentation. When the call is resumed, the Polycom endpoint screen is frozen. The TX9x00 displays a message indicating that call reached the maximum number of participants. The call is dropped. After the CTS 1. After the main call is established, an audio-only call is added, which causes the main call to drop.

The presentation is shown on the TX9x00 for only 3—4 seconds. For complete Cisco TelePresence software compatibility and device interoperability information, go to this page:. The following sections contain new features in the Cisco TelePresence System 1. CTS software release 1. You must upgrade to CTS 1. Note These vulnerabilities are not fixed in CTS 1. However, the CTS 1. Cisco has performed regression testing to test the OpenSSL vulnerability for TelePresence calls to and from endpoints running the different software versions.

Table 1 shows the software versions in which the calls between selected endpoints were verified as secure with the updated releases. Releases updated for OpenSSL fixes:. Releases without OpenSSL fixes:. Secure 1. Note Beginning with CTS 1. If your system uses CTS software release 1.

Note If you plan to downgrade from TX 6. If you do not install 1. If you encounter issues with this procedure, contact your Cisco technical support representative. Locate the endpoint that requires a Live Desk number. Step 4 Enter a dial number in the Live Desk Number field.

If a meeting participant has a laptop plugged in for presentation sharing and the document camera turned on, the Cisco Touch device or Cisco TelePresence IP phone now automatically displays the Presentation Privacy Alert when the participant turns off the document camera. The participant selects Everyone to share the presentation from the laptop or No One to keep the presentation hidden.

Several caveats were resolved in CTS release 1. CTS Release 1. The TX requires the following minimum software releases:. Note The TX may ship with Release 1. In that case, you must upgrade to Release 1. For more information, see the following resources on Cisco. The TX9x00 requires the following minimum software releases:.

The CTX Tests tab enables you to perform acoustic tests on a room to determine the acoustic suitability of that room for the installation of a Cisco TelePresence System. There are two tests you can perform, a reverberation test and a noise level test. During the reverberation test, the CTS plays audio chirps and collects the average sound decays for each frequency.

During the noise level test, the CTS collects sound pressure levels and noise criteria for each frequency. This test lets you test each of the three primary microphones left, right, center , and the presentation audio input. When the test is run, any sound picked up by the selected microphone is played on the speakers after a short delay.

The following enhancements are controlled from the Cisco Unified Communications Manager Administration interface:. The Unified CM administration displays the touch device as a single line device rather than a shared line Cisco Unified IP phone device.

This section contains the following caveat information:. The release was updated for compatibility with other TelePresence administration releases being updated to address security vulnerabilities. Symptom When a presentation is shared using the CTS, the presentation cannot be seen by the other conference participant.

On January 27, , a buffer overflow vulnerability in the GNU C library glibc was publicly announced. This vulnerability is related to the various gethostbyname functions included in glibc and affect applications that call these functions. This vulnerability may allow an attacker to obtain sensitive information from an exploited system or, in some instances, perform remote code execution with the privileges of the application being exploited.

This vulnerability is documented in CVE A Cisco Security Advisory has been published to document this vulnerability at:. This bug has been opened to address the potential impact on this product. Conditions Exposure is not configuration dependent. Workaround None. Upgrade to latest version with fix when available. Symptom The user directory is not shown after an upgrade of Unified CM from 9.

Conditions This condition affects the following systems:. Conditions This issue occurs very rarely during point-to-point calls when one of the endpoints is a Cisco TelePresence System Workaround A reboot of the system can temporarily resolve the issue, but does not prevent the issue from recurring in subsequent calls.

Symptom You experience one-way audio during a conference. Conditions The following conditions cause the issue:. This type of call is known as an interop call. Conditions This condition is seen on a CTS when the video quality is set to p good. Symptom During a conference with a system using a C60 codec, the CTS immersive system does not see the presentation that is shared from the C60 system.

Conditions This caveat occurs under the following conditions:. A C60 system calls the Cisco TelePresence immersive system and shares a presentation. A C60 system adds a new audio participant to the call. After the audio add-in, the immersive system does not see presentation from the C60 system. Symptom Slow login to admin GUI. In some cases, call will drop after 45 to 50 minutes.

This issue was resolved in software releases CTS 1. If the TC user attempts to switch the screen in view by tapping on the corresponding microphone, the TC screen sometimes goes blank. Conditions Issue occurs sometimes, after more than 15 minutes have elapsed in the call. Workaround Perform a hold-and-resume on the TC endpoint. Conditions This issue might occur when multiple admin UI sessions are open simultaneously. Symptom During boot-up, the images that appear on the center display screen do not fade away.

This might cause the images to burn into the plasma screen. Conditions This issue might occur if the system is turned on before the network is connected, or if the system is reset by software or by power and the endpoint cannot reach the network DHCP server. Workaround Assign a static address to the TX endpoint, or upgrade the system software to 1. Symptom When a system running software release 1.

Conditions The system is running software release 1. Conditions When an EX90 endpoint shares a presentation with a CTS endpoint during the first 15 seconds of a call, the presentation does not display. Workaround Share the presentation from the EX90 after the first 15 seconds of the call, or unshare and share presentation after 10 to 20 seconds.

After resuming the call, the CTS shares the same presentation, which does not display on Jabber. Symptom The CTS web UI shows that an audio recording is in progress, even when a recording is not in progress or the system is not in a call. Please wait and try again in two minutes. Symptom A non-secure endpoint joins a secure TelePresence call between two endpoints one of which is a TX9x00 , which triggers a downgrade to non-secure.

Then the TX9x00 endpoint is dropped from the call. Conditions TX9x00 is dropped if the third, non-secure endpoint joins within the first 20 seconds of the call. Workaround The third endpoint can successfully join the call minutes after the call starts. The TX9x00 will not be dropped.

Symptom After performing a nonsecure audio add-in during a secure TelePresence Server call using TLS, the call becomes partially secure and is dropped. Workaround Perform a hold-and-resume on the CTS after the audio add-in is disconnected.

Symptom Remote endpoint of a CTS point-to-point call sees a green screen when trying to view a presentation from the local endpoint. Conditions During a point-to-point call, when the local endpoint shares a presentation, the remote endpoint sees only a green screen. Symptom In a multipoint call where one endpoint is a CTS system, when another endpoint shows a presentation, the CTS sometimes does not see the presentation. Conditions Issue occurs during a multipoint call where one of the endpoints is a CTS system.

In some cases, multiple endpoints do not see the presentation, or the presentation appears intermittently. A dummy value may be used if needed. Symptom The left and right microphones of the CTS system do not work. Conditions While running any software release later than 1. The center microphone does work. Conditions After a CTS endpoint makes several calls in a row, the endpoint begins to function slowly and becomes unresponsive, then crashes.

Symptom The brightness of the lights in the CTS system cannot be adjusted. Conditions When TX and CTS are in a call and attempt to share a screen or display a presentation, it does not show up on some third-party display monitors. There are no unresolved caveats in CTS Release 1. Conditions Ghosting effect may occur within first 13 minutes of call, and occurs on a single display. Ghosting effect may be observed on both systems in the call.

Workaround Either downgrade your system to 1. Codec also recovers from a DSP reset while in a TelePresence conference, but does not drop the conference. Workaround Ignore these messages. They do not indicate any problems with your system. When the other conference participant performs a hold and resume operation on its CTS system, the single microphone unmutes. Symptom Cannot get a microphone count for the TX There are no microphone tags in the configuration file.

Symptom Edge of CTS screen sometimes displays repeating pixels. Conditions During a TelePresence conference, some pixels on the border of the TelePresence screen may appear more than once. The CTS does not respond to this trigger. Workaround CTS endpoints can dial in after the TC5 endpoint joins, or redial after getting dropped. Conditions When a p endpoint that is configured for a lower bandwidth calls into a CTMS conference that is running at a higher bandwidth, the entire conference downgrades to p.

Workaround Configure all p endpoints for the same bandwidth. Workaround Either downgrade the system to 1. Conditions This issue occurs during a point-to-point or multipoint TelePresence conference, when a CTS endpoint is added in as audio-only. Symptom Camera focus target does not display properly on screen when setting up a TX 47 system for a round or square table.

Conditions When configuring the TX 47 camera for a round or square table, the camera focus target displays as a dot instead of a target box. Symptom If a presentation is shared from the TX9x00 when the call is connecting, the presentation is not received on the SX20 endpoint. Workaround Unplug the VGA cable and plug it in again. Or wait 2—3 seconds after the call connects to share the presentation.

Conditions Attempted to power off the document camera from the phone. The MIDlet remains in hung state. Functions such as zooming and focusing do not work. Workaround Exit from the option on the phone. Then start the option again. Symptom The utils system presentation command is not available in the CLI.

Conditions The endpoint joins an H. Symptom Presentation audio unavailable with TX is in self-view mode. Conditions If a laptop is connected to the presentation cable, and presentation audio and video is played, if the system is then put into self-view mode, the presentation audio will not be heard. Symptom Video freezes when exiting self-view mode when presentation is being displayed.

Conditions If a laptop is connected and a presentation is being displayed on the main display, and self-view mode is entered and exited, the presentation video display freezes. Workaround Initiate a video call to remove frozen video. Symptom When a Microphone Calibration test is stopped before services restart, all other UI options become unavailable. Conditions When starting a Microphone Calibration test in the Administrative UI, the system stops and restarts services to run the test.

If the Stop button is clicked while these services are restarting, all other troubleshooting options in the UI are made unavailable. Workaround Wait until services have restarted before stopping the test. Symptom On a TX or a TX system, if CUCM is configured for three microphones, but six microphones are connected to the TX, during an audio-only call, the extra microphones are not enabled. Conditions The TX or TX system should act in a similar manner to the CTS , in that during an audio-only call, all connected microphones should be enabled regardless of the CUCM configuration for number of microphones.

You must Apply the settings in the Table Configuration page to save your settings and overwrite the default values on the codec. Conditions In a multipoint call, reverberation is heard on a CTS speaker when a meeting participant in a TX9x00 room turns their head. The participants voice is then picked up by multiple microphones in the TX9x00 room.

This results in reverberation on a CTS system connected to the call. Workaround Meeting participants should speak directly into the microphones. Symptom Running two Reverberation tests in succession may cause the second test to hang. Conditions When performing a Reverberation test, if a second Reverberation test is performed immediately after the initial test, the second test may never stop running and display results.

This issue occurs intermittently. Symptom Additional microphones used for audio-only conferencing are not disabled during video calls. Conditions On a TX or TX system that has additional microphones installed for audio-only conference capability, the extra microphones are not disabled during video calls.

This may cause audio feedback. This issue has been resolved in Release 1.
