Problem   
Your MCU blade is offline. 
Solution   
Open your Media Server administration page. Select Resource Management > MCU. The 
status of the blade should be “online” and “connected.” If it is not, select the desired MCU link. Ensure 
the radio button Online has been selected. 
Possible Cause   
The prefixes from the MCU to the Media Server are not synchronized. 
Solution   
Synchronize the prefixes from MCU to Media Server. 
Possible Cause   
Your call was set up using an audio-only prefix. 
Solution   
Ensure that the call is set up using a video prefix. 
Possible Cause   
The video rate is not set properly. 
Solution   
Make sure the video rate in the administration global settings is set properly. Sign in to the 
Administration Center. Select System Configuration > Meeting Configuration > Global Settings > 
Global Video Mode
. Set the standard rate to 384 kbps maximum. Set the high rate to 2 Mbps maximum. 
Possible Cause   
MTP is enabled on the trunk from the CUCM to the Cisco MeetingPlace application 
server. 
Solution   
Make sure you disable MTP on the trunk from CUCM to the Cisco MeetingPlace application 
server. 
Problem   
A video conference call drops after 20 seconds. There is no video or audio on during that time. 
The SIP B2BUA log from the infocap shows that Cisco Unified Communications Manager send TIAS 
with a negative value, [.INFO] [..MESSAGE] b=TIAS:-1000. This is because the "Video Call 
Bandwidth" field was set to "None" in the Region setting. 
Solution   
Set the correct value for the "Video Call Bandwidth" field.

Poor Video Quality
Problem   
The video has a pixelated image or poor quality.
Possible Cause   
Network issues are causing packet loss between the endpoint and Cisco Unified 
MeetingPlace.
Solution   
Check the network for and correct any packet loss or excessive bandwidth utilization along the 
path between the video endpoint and Cisco Unified MeetingPlace.
Possible Cause   
(
) The input stream is from the Cisco Unified IP Phone 7985. This 
potentially affects all video calls with Cisco Unified MeetingPlace when the Cisco Unified 
MeetingPlace 
 is set to “standard rate” (384kb).
Solution   
In the Administration Center, set the 
 field to High rate.
Solution   
For full compatibility with Cisco Unified MeetingPlace, upgrade the Cisco Unified 
IP Phone 7985 to application load 4.1(7) or later.
