will still be On. Most likely this will result in a failing SSL
handshake and a failover to TCP if default transport is set
to Auto by the CUCM. A TCP registered endpoint will not
be able to make secure calls.
Also CUCM provisioning will turn DisableListening on:
xConfiguration SIP DisableListening: On. This setting has
to be set to off in order for the endpoint to register to VCS.

Endpoints registered to
CUCM
Since a CUCM will not issue an “Install/Update LSC
(Locally Significant Certificate)” request to the Endpoint
unless explicitly configured to do so, a factory reset will
effectively hinder the EP from being able to re-register to
the (same) CUCM after the reboot. The only recourse is for
the sysadmins to tick “Install/Update LSC” for the device in
question on the CUCM side.

The Cisco VCS Provisioning (TMS Agent) wizard is
available from the Touch 8 for the C20, C40, C60, C90,
SX20 and all other systems with such a codec inside, yet
only the Cisco CTS EX60/EX90 and Cisco CTS
MX200/MX300 is supported.

CUCM provisioned
endpoints
When an endpoint that is provisioned to CUCM loses
network connectivity and is restored again, it doesn’t re-
provision to a second CUCM subscriber if the previous
CUCM subscriber is not available. The reason is that
failover is yet not supported.

Any
There is a hardware incompatibility between the C-Series
systems and some NEC monitors. So far this is seen with:
NEC LCD4020 and NEC P401. This incompatibility will
cause the monitor to wake up from sleep mode even if the
codec is still in sleep. This happens when the monitor is
connected using HDMI to HDMI. A workaround is to use
the monitors DVI input.

Any
The C series codecs and units with such a codec inside it
do not meet the Cisco password policy. It is highly
recommended to set a password on the unit during install
using the API command: ‘systemtools passwd’
N/A
TC4.x and later
If the ‘admin’ user is deleted, the TMS will not be able to
manage the system. At the same time the ‘admin’ user with
a blank password will be recreated during next reboot if no
other user with admin access exists.
N/A
TC4.x and later
xFeedback register Event/KeyDown masks the keys
pressed on the remote control with a ‘*’. This is a security
measurement to prevent key logging from the remote
control. The ‘*’ can be used to detect that someone has
pressed a button on the remote control.
N/A
Cisco TelePresence
Touch
The Cisco TelePresence Touch 8 must be connected to the
same subnet as the codec it is pairing to.
