Related Problems
Cisco IP Phone 7970
There are known problems on the Cisco IP Phone 7970 connected to a PC running Cisco VT Advantage.
Problem Description (CSCed91521)
A large number of simultaneous audio/video calls can make the Cisco IP Phone 7970 unresponsive.
Workaround : When video capabilities are enabled for the Cisco IP Phone 7970, reduce the maximum number of calls from the limit of 200 to a maintainable level of 150 on Cisco CallManager.
Refer to CSCed91521 for more information.
Problem Description (CSCee54354)
Start Cisco VT Advantage on a PC connected to the Cisco IP Phone 7970 and make a video call. Disconnect the PC from the Cisco IP Phone 7970 and reconnect it to another phone. Then reconnect the PC to the original Cisco IP Phone 7970 while the original call is still up. The Cisco IP Phone 7970 does not allow a TCP CAST connection from Cisco VT Advantage on the associated PC.
Workaround: Restart the Cisco IP Phone 7970.
Refer to CSCee54354 for more information.
Problem Description (CSCee01878)
The Cisco IP Phone 7970 can become unresponsive when handling a large number of short duration audio/video calls over an extended period of time.
Workaround: Restart the Cisco IP Phone 7970.
Refer to CSCee01878 for more information.
Cisco IP Phone 7960G
There are known problems on the Cisco IP Phone 7960G connected to a PC running Cisco VT Advantage.
Problem Description (CSCee05824)
Sometimes Cisco VT Advantage fails to connect to a Cisco IP Phone 7960G. This might be caused by a loose connection on the Ethernet cable or a loose connection on a docked laptop.
Workaround: Make sure the physical connections between the PC and Cisco IP Phone 7960G are secure. Power cycle the Cisco IP Phone 7960G.
Refer to CSCee05824 for more information.
Problem Description (CSCee49896)
During a point-to-point (2 party) call, the video on both PCs freezes when Cisco CallManager has been restarted.
Workaround: None.
Refer to CSCee49896 for more information.
Cisco CallManager
There is a known problem on Cisco CallManager 4.0(1), Service Release 2.
Problem Description (CSCee36798)
No audio or video if you mute the audio before connecting to a video call on a Cisco IP/VC 3540-MC10A MCU.
Workaround: None.
Refer to CSCee36798 for more information.
General PC
There are some known problems related to PCs.
Problem Description (CSCee29961)
A blue screen might occur when an older version of Cisco Security Agent is running. The driver name is CSA_*.sys ("*" represents many different character possibilities). It is not clear whether the crash only occurs when Cisco VT Advantage is active.
Workaround: Upgrade the Cisco Security Agent to version 4.0.2.624 or later.
Refer to CSCee29961 for more information.
Problem Description (CSCee44874)
A blue screen crash in Windows 2000 has been seen when either inserting or removing a USB device. Note that this also includes docking and undocking from a port replicator. While the dump is occurring, the system will indicate that the error occurred in UHCD.SYS.
Workaround: The Microsoft patch can be found and applied from the Cisco VT Advantage software download page. Refer to the Cisco VT Advantage Readme file for file location and instructions.
Refer to CSCee44874 for more information.
Problem Description
When the Intel NIC driver e100bnt5.sys is not running at a minimum level of 7.1.12, blue screen crashes labelled as NDIS.sys have been observed during testing with and without Cisco VT Advantage installed on the PC.
Workaround: This blue screen crash error can be provoked with or without Cisco VT Advantage installed on the PC. To avoid this crash, it is recommended that users upgrade to the minimal driver level of 7.1.12 from Intel's web site: http://www.intel.com/
Problem Description
Large video packet loss resulting in poor video quality, frozen or no video is present when the "Media Type" settings on a PC are not set to "Auto Select". The default setting may vary based on PC manufacturer. A port mismatch between the Cisco IP Phone and the PC will cause this problem.
Workaround: On PC's running Windows 2000 follow these steps:
1.
2.
3.
4.
5.
Administrators should ensure that users have a 100 Mbps full duplex connection between their phones and PCs.

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
