Symptoms: When the VCS sends a SIP INVITE, the P-Asserted-Identity field does not
contain a display name. This results in no caller ID on the far end. Currently the PAI header
will look like this:
P-Asserted-Identity: <sip:name.ex60@ name.local>
Instead, it should look like this:
P-Asserted-Identity: "Full Name" <sip: name.ex60@ name.local>
Conditions: When VCS sends an invite to CUCM (or other 3rd party SIP server), the P-
Asserted-Identity field does not contain a display name while VCS run X7.2 or older software
version.

Symptoms: Logins on the web and CLI can be slow to complete.
Conditions: When remote authentication is enabled, all logins (not just remote users) can be
delayed by many seconds if the LDAP server is slow to respond.
Workaround: None, delays from the LDAP server are outside the control of the VCS.

Symptoms: A crash report is seen on the VCS for the "python" application, with statements
such as "unable to read python frame information".
Workaround: None, however Python processes on the VCS will immediately restart and this
should not disrupt service.

Symptoms: The hard disk on a VCS can become full if the log rotation program fails. This
can lead to unexpected errors such as database and web access issues.
Conditions: This will occur if the log rotation program fails, and the log files grow to fill up
/var/log.
Workaround: Delete the non-rotated log files in /var/log, or move them out of the way to
/mnt/harddisk.

Symptom: Cisco TelePresence Video Communication Server (VCS) may report an early fan
"Hardware Failure" alarm condition that does not impact the server.
Condition: A VCS running a release prior to X7.2.1 will report a hardware failure alarm if a
single fan reports a speed below 7670 RPMs. The impact of this threshold is that fan
fluctuations that do not impact the functionality of the server have led to units being
prematurely replaced.
Starting in X7.2.1, new alarms values based upon extensive testing have been implemented.
Workaround: For systems running with releases prior to X7.2.1, you can safely ignore the
alarm if the VCS displays only one fan alarm message for a single fan. Customers should
monitor such alarms manually.
The VCS includes temperature alarms that are raised if the VCS reaches an unsafe
temperature.
Additional Information: You can log in to the VCS as root and run the "sensors" command
to get more detailed information on system fans and temperature.

Symptoms: A H323/SIP interworked G729 audio call may drop after the first session refresh.
Conditions: Offer/answer in H323/SIP interworked case may not send G729 capability in
SDP re-invite (at session refresh) since G729 can be signaled multiple times in H323 but only
once in SDP.
Workaround: Use SIP only.
