OL-21851-01
Possible Cause
MIDlet Upgrade Issues
The phone firmware is unable to uninstall the
older version cleanly to make way for the
new version. The issue happens during
upgrade of the MIDlet if the phone is not
reset after the upgrade.
Authentication Issues
The MIDlet does not find Authentication
Server URL or it does not recognize its
format.
Supported Character Issues
Non-English characters are used on phone
device profile.
CTL File Issues
The CTS was associated with a different
secure Cisco Unified CM at one time and the
CTS preserved the previous Certificate Trust
List (CTL) file.
CTS Unknown Issues
Cisco TelePresence System could be
unknown:
• Cisco Unified CM does not know about
the CTS.
• CTS is not registered because it is
unplugged.
• CTS MAC address is entered incorrectly.
