Summary

Any
SIP signaling packets are not tagged with QoS.
87376/CSCtr28267
TC4.X
OCS registration is broken in TC4.x
TC4.x
If you downgrade from TC4.x.x to any software
less then TC4.0.0 and have set the IP stack to
IPv6, the system will be unusable. The stack
will still think it should do IPv6 even though
there is no place to configure this in pre
TC4.0.0 code. The workaround will be to factory
reset the system. Even if the system does not
report any IP address, it will still have an IPv4
address. If you can’t get hold of this address,
you will have use RS-232 to restore the unit or
the procedure of using the power button (for
C20, EX60 and EX90).
89393/CSCtr32417
TC4.x
Dual stack for IPv4/IPv6 does not work as
intended. If you set the device to IPv6, you will
not be able to reach any service by using an
IPv4 address. This will be addressed in an
upcoming release.
87026/CSCtr32389
TC4.0 and above
The composite output will display black frames
when displaying more than two windows. It will
set up the black borders but you will not see
any video.
N/A
TC4.1.0
The Cisco TelePresence Touch screen does
not support up loadable layout families. Hence
you should not use the Cisco TC Console to
upload layouts to a system with the Cisco
Touch screen attached.
N/A
Cisco TelePresence Touch
TC4.1.0/TT2.1.0
The Cisco TelePresence Touch must be
connected to the same subnet as the codec it is
pairing to.
N/A
Cisco TelePresence Touch
TC4.1.0/TT2.1.0
The Cisco TelePresence Touch currently do not
support:
Changing the main source
N/A
TMS 12.6 or below when upgrading to
TC4.0.0 and above
Starting with TC4.0, the security model used by
the system changes which impacts compatibility
with existing installations of TMS. The
incompatibilities will result in:
1) Upgrading endpoints from a version less
than TC4.0 to a version TC4.0 or higher using
existing versions of TMS (12.x or lower) will
appear to have failed in TMS. Additionally, the
endpoint will not get the required release key
updated, so the endpoint will not be able to
make calls until a release key has been entered
into the system.
2) After an endpoint is upgraded to TC4.0 or
2) After an endpoint is upgraded to TC4.0 or
newer, the system will have an incorrect
username or password error message in TMS
and TMS will not be able to communicate with it
properly.
