Possible Cause
The Cisco TelePresence Recording Server
(CTRS) Studio Mode recording feature is not
working and the room has been
unsubscribed.
One or more of the rooms in a conference
does not support the feature.
Back-to-back calls with Session Border
Controller (SBC) drop when the active
Cisco Unified CM service is stopped or the
server is rebooted.
In a SIP call, Cisco Unified CM does not
recognize H.323 gateways, which support
audio but do not support video (a
Cisco AS5400 for instance). When the
Cisco Unified CM detects this type of
"unknown" box on the receiving end, a 503
server error message is sent and the call does
not connect.
TCP Issues
MIDlet cannot establish TCP connections
with the CTS.
CTS IP Address Issues
Possible incorrect CTS IP address is assigned
to the phone profile authentication server
URL.
Verifying and Troubleshooting the Cisco TelePresence System Configuration
Possible Solutions
Check Room View on CTS Manager to verify
whether a CTS device is capable of supporting
the features in a specific room. Then check
your Cisco Unified CM configuration settings
to configure the device. See
"Configuring Cisco Unified Communications
Manager for the Cisco TelePresence System."
Do not place a call during failover operations.
Ensure that the receiving end of a call supports
audio-visual (AV) streams.
Ensure that the correct CTS IP address is
1.
in the Authentication Server URL for the
phone device in Cisco Unified CM.
2. Click Save.
3. Reset the phone.
