Upgrading CTS Codec Firmware
The procedure to upgrade CTS firmware is the same as the firmware upgrade procedure for the
Cisco Unified CM IP phones. See the Configuring the Cisco Unified IP Phone and the
Cisco TelePresence System Enhanced Phone User Interface (MIDlets) chapter of the
Communications Manager Configuration Guide for the Cisco TelePresence System
instructions.
To upgrade CTS firmware, follow these general steps:
Step 1
Download the firmware file from Cisco.com.
Upload the firmware file to the TFTP directory of your Cisco Unified CM TFTP server.
Step 2
Restart the TFTP server.
Step 3
Change the firmware filename for the system(s) that you want to upgrade (either via the Device Defaults
Step 4
page, or on a per system basis) in the Cisco Unified CM Administration interface.
Click the Restart button in Cisco Unified CM for the device(s) that you want to upgrade.
Step 5
OL-13676-05
Possible Cause
DSP failure due to incompatible CTS
software version.
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.
Possible Solutions
CTS devices are backward compatible up to
two CTS Software Releases. You may want to
upgrade your software.
Check Room View on CTS-Man 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 the
Cisco Unified Communications
Manager Configuration Guide for the
Cisco TelePresence System
information.
